License and Certificate of Compliance Terms, 8872-8892 [2011-3493]

Download as PDF erowe on DSK5CLS3C1PROD with RULES 8872 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations expenses, and $118,850 for office expenses. Budgeted expenses for these items in 2009–2010 were $4,030,500, $725,000, $535,000, and $123,750, respectively. The Board recommended decreasing the assessment rate due to an expected increase in the quantity of assessable walnuts in the 2010–11 marketing year. Prior to arriving at this budget, the Board considered alternative expenditure levels but ultimately decided that the recommended levels were reasonable to properly administer the order. The assessment rate of $0.0174 per kernelweight pound of assessable walnuts was derived by dividing anticipated expenses of $6,812,100 by expected 2010–11 shipments of California walnuts. Merchantable shipments for the year are estimated at 391,500,000 kernelweight pounds, which should provide $6,812,100 in assessment income and allow the Board to cover its expenses. Unexpended funds may be retained in a financial reserve, provided that funds in the financial reserve do not exceed approximately two years’ budgeted expenses. If not retained in a financial reserve, unexpended funds may be used temporarily to defray expenses of the subsequent marketing year, but must be made available to the handlers from whom they were collected within five months after the end of the year, according to § 984.69 of the order. A review of historical information and preliminary information pertaining to the upcoming crop year indicates that the grower price for the 2010–2011 season could range between $1.42 and $1.88 per kernelweight pound of assessable walnuts. Therefore, the estimated assessment revenue for the 2010–2011 season as a percentage of total grower revenue could range between 0.9 and 1.2 percent. This rule continues in effect the action that decreased the assessment obligation imposed on handlers. Assessments are applied uniformly on all handlers, and some of the cost savings may be passed on to growers. The Board’s meeting was widely publicized throughout the California walnut industry, and all interested persons were invited to attend the meeting and participate in Board deliberations on all issues. Like all Board meetings, the June 11, 2010, meeting was a public meeting, and all entities, both large and small, were able to express their views on this issue. This rule imposes no additional reporting or recordkeeping requirements on either small or large California walnut handlers. As with all Federal marketing order programs, reports and VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies. USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule. Comments on the interim rule were required to be received on or before November 15, 2010. No comments were received. Therefore, for the reasons given in the interim rule, we are adopting the interim rule as a final rule, without change. To view the interim rule, go to https://www.regulations.gov/ search/Regs/home.html# documentDetail?R=0900006480b4f686. This action also affirms information contained in the interim rule concerning the Executive Orders 12866 and 12988, the Paperwork Reduction Act (44 U.S.C. Chapter 35), and the E-Gov Act (44 U.S.C. 101). After consideration of all relevant material presented, it is found that finalizing the interim rule, without change, as published in the Federal Register (75 FR 55944, September 15, 2010) will tend to effectuate the declared policy of the Act. AGENCY: is amending its regulations that govern licensing requirements for the independent storage of spent nuclear fuel. These amendments include changes that enhance the effectiveness and efficiency of the licensing process for spent nuclear fuel storage. Specifically, they extend and clarify the term limits for storage cask Certificates of Compliance (CoCs) and independent spent fuel storage installation (ISFSI) specific licenses. The amendments also provide consistency between the general and specific ISFSI license requirements, and allow general licensees subject to these regulations to implement changes authorized by an amended CoC to a cask loaded under the initial CoC or an earlier amended CoC (a ‘‘previously loaded cask’’). DATES: Effective Date: This final rule is effective on May 17, 2011.

Background On April 29, 2002, the Virginia Power and Electric Company (Dominion) submitted an application to renew Special Nuclear Materials (SNM) License SNM–2501 for the Surry ISFSI. SNM–2501 authorizes the storage of spent nuclear fuel in casks at the Surry Nuclear Power Plant. In the renewal application, Dominion requested an exemption from the 20-year license renewal term specified in 10 CFR 72.42(a) and sought approval for a 40year license renewal term. Similarly, on February 27, 2004, Progress Energy Carolinas, Inc. submitted an application for the renewal of H. B. Robinson’s ISFSI license which requested an exemption from the provisions of § 72.42(a), so that the license renewal period for the H. B. Robinson’s ISFSI could be extended from 20 to 40 years. The NRC staff determined the 40-year renewal exemption request to be a policy decision, not a technical one, because the safety evaluation indicated sufficient technical information had been provided in the application to grant the 40-year renewal period. As a result, a Commission paper (SECY–04– 0175) entitled, ‘‘Options for Addressing the Surry Independent Spent Fuel Storage Installation License-Renewal Period Exemption Request,’’ was submitted on September 28, 2004, to request Commission approval of the Surry 40-year renewal exemption request. On November 29, 2004, the Commission issued a Staff Requirements Memorandum (SRM) for SECY–04–0175, which authorized the NRC staff to approve a 40-year license renewal term for the Surry ISFSI, with appropriate license conditions to manage the effects of aging. The SRM further directed the NRC staff to: (1) Initiate a program to review the technical basis for future rulemaking; (2) provide recommendations on the license term for part 72 CoCs for spent nuclear fuel cask storage systems; and (3) apply the Commission-approved PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 8873 guidance for part 72 renewals to future specific license exemption requests without further Commission approval. In response to this direction, the staff submitted a Commission paper (SECY– 06–0152) entitled, ‘‘Title 10 Code of Federal Regulations part 72 License and Certificate of Compliance Terms,’’ on July 7, 2006, to recommend the scope of rulemaking. In an SRM, dated August 14, 2006, the Commission authorized the staff to proceed with rulemaking proposals described in SECY–06–0152. In addition, the Commission specifically directed the staff to address the following points in the rulemaking: (1) Clarify the start of the 20-year term limit for cask designs approved under general license provisions; (2) identify whether the cask vendor or licensee is responsible for applying for the CoC renewals; (3) discuss possible conflicts that could arise for storage cask designs that are granted a license term extension and that have been approved for transport with a different license term; (4) discuss how the cask expiration dates are tracked at each general license site so that it is clearly understood when the CoC for each cask design must be renewed; and (5) clarify the difference between CoC ‘‘approval’’ and ‘‘renewal.’’ As this rulemaking commenced, the NRC staff identified a related issue regarding its approval of Amendment 4 to CoC 72–1026, which revised cask monitoring and surveillance requirements for the BNG Fuel Solutions W–150 storage cask. Subsequent to the approval, the certificate holder requested guidance from the NRC on the implementation of the changes authorized by the CoC amendment to previously loaded casks. In addition to this request, the NRC staff became aware of the belief among some general licensees that changes authorized by CoC amendments can be applied to previously loaded casks without prior NRC approval, if an analysis under § 72.48 is performed. The NRC staff determined that under the current regulations, changes authorized by CoC amendments cannot be applied to previously loaded casks without express NRC approval, if such change results in a change to the terms or conditions of the CoC under which the cask was loaded. A previously loaded cask is bound by the terms and conditions (including the technical specifications) of the CoC applicable to that cask when the licensee loaded the cask. Therefore, under the current regulations, general licensees that want to apply changes approved by a CoC amendment to a previously loaded cask must request an exemption from the E:\FR\FM\16FER1.SGM 16FER1 8874 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations NRC if these changes alter the terms or conditions of the CoC under which that cask was loaded. In the SRM for COMSECY–07–0032, dated December 12, 2007, the Commission stated that it did not object to the staff expanding the scope of the proposed rulemaking to include the following two issues: (1) To extend the terms of specific ISFSI licenses, for both initial and renewal terms, to not to exceed 40 years; and (2) to allow a general licensee to apply changes for a CoC amendment to a previously loaded cask without express NRC approval, while still ensuring that this action protects public health and safety. In the August 14, 2006, SRM for SECY–06–0152, the Commission directed the NRC staff to be as transparent as possible in developing the proposed rule package, including making draft text available for comment to stakeholders, and holding public meetings, if necessary, before formal submission of the proposed rule to the Commission. In response, the NRC staff held public meetings on November 7, 2006, and February 29, 2008, to discuss the technical basis of the rulemaking with stakeholders. In addition, on August 4, 2008, the NRC staff made preliminary draft rule text available for comment to stakeholders on Regulations.gov (Docket ID NRC–2008– 0361). The only external stakeholders that submitted comments were the Nuclear Energy Institute and Florida Power and Light. The comments generally supported the rulemaking. The ‘‘Discussion’’ section of this document includes NRC responses to significant stakeholder comments. The NRC published the proposed rule, ‘‘License and Certificate of Compliance Terms’’ in the Federal Register on September 15, 2009 (74 FR 47126), for public comment. The NRC received five comment letters on the proposed rule. These comments and the NRC responses are discussed in Section III of this document, ‘‘Summary and Analysis of Public Comments on the Proposed Rule.’’ II. Discussion erowe on DSK5CLS3C1PROD with RULES A. What action is the NRC taking, and why? The NRC is revising part 72 requirements for specific and general ISFSI licensees and part 72 requirements pertaining to CoCs to enhance the effectiveness and efficiency of the licensing process. For specific ISFSI licenses, the Commission is codifying a technical approach consistent with that applied in granting the 40-year exemptions for the VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 Surry and H. B. Robinson specific ISFSI license renewals, so that all specific ISFSI licensees will have the flexibility to request initial and renewal terms not to exceed 40 years while ensuring safe and secure storage of spent nuclear fuel. For CoCs, the Commission is also allowing the flexibility for CoC applicants and CoC holders to request, respectively, initial terms and renewal terms not to exceed 40 years. The response to Question ‘‘C’’ of this section discusses the technical basis for this change. Under this change, applicants and CoC holders will be required to demonstrate that design and operational programs are suitable for the requested term. The NRC staff has developed a standard review plan (SRP) for renewal applications. The final rule amendments also clarify the term (length) of the general license, particularly as the general license term relates to CoC renewals (see the response to Question ‘‘I’’ of this section for further detail). For both specific licenses and CoCs, the final rule adds a requirement that renewal applicants must provide TLAAs and a description of an AMP (see the responses to Questions ‘‘F’’, ‘‘G’’, and ‘‘H’’) to ensure that storage casks will perform as designed under extended license terms. The NRC is replacing the term ‘‘reapproval,’’ which is used to describe the process of extending the CoC terms, to ‘‘renewal’’ for consistency with specific license terminology. Question ‘‘E’’ of this section discusses the rationale for this change. The final rule will also allow general licensees to implement changes authorized by a CoC amendment to a previously loaded cask, provided that the loaded cask then conforms to the CoC amendment codified by the NRC in § 72.214 and thus, continues to ensure the safe and secure storage of spent nuclear fuel. Question ‘‘N’’ of this section discusses the rationale for this change. B. Whom does this action affect? The final rule will affect part 72 specific and general licensees and CoC holders and applicants for a CoC. C. Why is the NRC increasing initial terms and renewal terms for specific ISFSI licenses from not to exceed 20 years to not to exceed 40 years? The NRC is amending § 72.42 to increase the initial terms and renewal terms for specific ISFSI licenses from not to exceed 20 years to not to exceed 40 years. This increase is consistent with the NRC staff’s findings regarding the safety of spent nuclear fuel storage, as documented in the renewal PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 exemptions issued to the Surry and H. B. Robinson ISFSIs. During the review for the Surry and H. B. Robinson renewal applications, the NRC staff evaluated the technical data resulting from an NRC-supported research program at the Idaho National Laboratory (INL), formerly Idaho National Engineering and Environmental Laboratory, and also considered experience with spent fuel storage casks used at Surry. Under the INL research program, INL opened a storage cask after the fuel had been stored for approximately 15 years. At Surry, several casks were also opened after less than 15 years of storage as a result of some faulty weather covers, which were corrected. Summaries of the findings regarding the condition of the fuel and cask components follow: (1) Cladding creep is a timedependent change in the dimension of the cladding resulting from high temperature and stress. It was considered as a potential degradation mechanism during storage. Confirmatory inspection of the spent fuel stored at INL verified that no cladding creep had occurred. The spent fuel in storage at Surry also supports this finding. The NRC staff expects very little to no fuel degradation at the end of an extended licensing period. The established limits for cladding temperature during storage accompanied by a continually decreasing level of cladding stress and temperature, further remove creep as a degradation mechanism. Assessment of these factors indicates that cladding creep will not be an issue during a 40 year term. (2) The NRC staff also expects limited degradation of other internal components because there are no significant corrosive influences in the inert environment, either for the fuel or for other components. The INL inspection verified that there was no indication of corrosion for any internal canister components. The NRC staff has also concluded that radiation levels are too low to significantly alter the properties of the metals for any storage canister components. (3) The other external components of the storage systems (which are exposed to weathering effects) would already be covered by an inspection and corrective action program, or routine maintenance, to ensure that any degradation will be identified and assessed for its importance to safety, and will be addressed through corrective actions to ensure continued safe operation of the storage system. Based on these findings, the Commission concludes that, with E:\FR\FM\16FER1.SGM 16FER1 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations appropriate aging management and maintenance programs, license terms not to exceed 40 years are reasonable and protect public health and safety. D. Can applicants apply for an initial term or renewal term greater than 40 years? This final rule amends § 72.42 by extending the term allowed for specific ISFSI licenses from not to exceed 20 years to not to exceed 40 years. This extension applies to both the initial terms and renewal terms. Any request for a term greater than 40 years would be processed as an exemption under § 72.7. The NRC does not plan to ordinarily grant license term requests for greater than 40 years. As discussed in Question ‘‘C’’ of this section, the NRC believes that terms that do not exceed 40 years are reasonable and provide adequate protection of public health and safety, if the applicant demonstrates to the NRC appropriate aging management and maintenance programs. If an applicant requests a specific license term greater than 40 years, that applicant would have to provide information on the long-term material degradation of spent fuel storage casks, as well as associated aging management activities, to justify safe operation during such an extended period, and the NRC would need to evaluate this information. erowe on DSK5CLS3C1PROD with RULES E. Why is the NRC changing the word ‘‘reapproval’’ to ‘‘renewal’’? The NRC is changing the word ‘‘reapproval’’ to ‘‘renewal’’ in the final rule to be consistent with the terminology used in other license requirements under part 72. Currently, § 72.240 uses ‘‘reapproval’’ to describe the process of extending the terms of CoCs. However, this terminology differs from other sections in part 72. For example, § 72.42 uses the word ‘‘renewal’’ to define the process for extending the term of specific ISFSI licenses, and § 72.212(a)(3) uses ‘‘renewals’’ to define the process for the continued use of storage casks of a particular design under a general license. Although ‘‘reapproval’’ and ‘‘renewal’’ are similar words, they are subject to different regulatory interpretations. ‘‘Renewal’’ typically implies a process whereby the term of an existing license or CoC is extended. As such, a renewal reaffirms the original design basis, perhaps with some modifications. ‘‘Reapproval,’’ on the other hand, implies a process to reevaluate the original design basis in accordance with current review standards, which may be different from VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 the standards in place when the cask design was initially certified. In addition, the Statements of Consideration (SOC) for the final rule (55 FR 29184; July 18, 1990) that added the general license provisions to part 72 stated that ‘‘the procedure for reapproval of cask designs was not intended to repeat all the analyses required for the original approval.’’ The referenced SOC also reported that, ‘‘the Commission believes that the staff should review spent fuel storage cask designs periodically to consider any new information, either generic to spent fuel storage or specific cask designs, that may have arisen since issuance of the Certificate of Compliance.’’ Clearly, measures would need to be taken if the ‘‘new information’’ involves safety concerns. These measures would depend on the nature of the safety concerns and the cask design. Requests for Additional Information (RAIs) may be generated during the renewal process to prompt applicants for CoC renewals to address such safety concerns. The NRC recognizes that a cask design certified years ago may not meet the latest standards, yet that design may be fully acceptable to continue to store spent fuel already loaded into casks of that design. If the cask design were subject to a reapproval process, and as such, to current standards, there is the possibility that certain components of the original design would not meet the current standards. Under this scenario, general licensees would be forced to remove the cask from service and repackage the spent fuel. Obviously, there are significant safety considerations if spent fuel were to be repackaged. When considering repackaging, safety considerations associated with the repackaging operation should be weighed against any safety concerns with leaving the spent fuel in its existing storage container. Although the NRC continuously updates its review standards, no compelling safety concerns have been identified to date that warrant the removal of spent fuel from a cask design that does not meet the latest review standards. Thus, the NRC concludes that the review of extending the term of a currently approved cask design is more in the nature of a renewal, because it is based on the cask design standards in effect at the time the CoC was approved, rather than a reapproval, which is based on the current standards. By replacing the word ‘‘reapproval’’ with the word ‘‘renewal,’’ the final rule revisions will remove ambiguity from the process for extending the terms of CoCs. PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 8875 F. Why is the NRC adding a definition for the term ‘‘time-limited aging analyses’’ (TLAAs)? Stakeholders asked for a definition of TLAAs when they reviewed the initial guidance document for the Surry and H. B. Robinson specific ISFSI license renewals. TLAA is a process to assess systems, structures, and components (SSCs) important to safety which have a time-dependent operating life. This final rule adds a definition of TLAA to the part 72 definitions section, § 72.3, and makes revisions to §§ 72.42(a)(1) and 72.240(c)(2), respectively, because TLAAs will be required for the renewal of a specific license and for the renewal of a spent fuel storage cask CoC. G. What is an ‘‘aging management program’’ (AMP)? An AMP is a program for addressing aging effects that may include prevention, mitigation, condition monitoring, and performance monitoring. The final rule adds a definition of AMP to the part 72 definitions section, § 72.3, because SSCs must be evaluated to demonstrate that aging effects will not compromise the SSCs’ intended functions during the renewal period. H. Why is the NRC requiring an AMP? The NRC is amending §§ 72.42 and 72.240 to require that applicants for specific license and CoC renewals describe a program, in their applications, for the management of issues associated with aging that could adversely affect SSCs. In this regard, degradation of the SSCs at an ISFSI, such as degradation due to corrosion and radiation, are time-dependent mechanisms and are expected to be addressed in renewal applications. AMP requirements will ensure that SSCs will perform as designers intended during the renewal period. AMP requirements will be reflected in the terms, conditions and technical specifications of the renewed CoC and thus made applicable to the general licensee per § 72.212(b). For specific licensees, AMP requirements will be reflected in the terms and conditions of the renewed specific license. I. Why is the NRC changing the 20-year general license term for cask designs approved for use under the general license provisions? When would a general license term begin and end? The final rule changes the 20-year general license term limit for the storage of spent fuel in casks fabricated under a CoC to be consistent with the revisions to CoC initial and renewal terms (which E:\FR\FM\16FER1.SGM 16FER1 erowe on DSK5CLS3C1PROD with RULES 8876 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations establish a CoC term not to exceed 40 years). Under § 72.210, a general license for the storage of spent fuel in an ISFSI at power reactor sites is issued to those persons authorized to possess or operate nuclear power reactors under 10 CFR parts 50 or 52. The general license is limited to that spent fuel which the general licensee is authorized to possess at the site under the part 50 or 52 license for the site. The general license is further limited to storage of spent fuel in casks approved and fabricated under the provisions of subpart L of part 72; the approved cask designs are listed in § 72.214. Currently, the general licensee’s authority to use a particular cask design under an approved CoC terminates 20 years after the date that the general licensee first uses the particular cask to store spent fuel, unless the cask’s CoC is renewed, in which case the general license terminates 20 years after the CoC renewal date. In the event the cask’s CoC were to expire, any loaded spent fuel storage casks of that design will need to be removed from service after a storage period not to exceed 20 years. This final rule amends §§ 72.3 and 72.212(a)(3) to clarify the term of the general license and to match the term of the general license to the term of the applicable CoC. The final rule also amends § 72.3 by adding a definition for the phrase ‘‘the term certified by the cask’s Certificate of Compliance,’’ which is defined to mean, for a CoC that is not renewed, the period of time commencing with the CoC effective date and ending with the CoC expiration date, and for a renewed CoC, the period of time commencing with the most recent CoC renewal date and ending with the CoC expiration date. The final rule amends § 72.212(a)(3) to clarify that the term of the general license runs through any renewal periods, unless otherwise specified in the CoC. In addition, the final rule also amends § 72.212(a)(3) to clarify that the general license term for those casks placed into service during the final renewal term of a CoC (i.e., during the CoC term immediately preceding the expiration of the CoC), or similarly, during the term of a CoC that is not renewed, begins when the cask is first used (i.e., when the cask is loaded with spent fuel) and expires after a storage period not to exceed the length of ‘‘the term certified by the cask’s Certificate of Compliance.’’ The following scenarios are provided as illustrative examples: Scenario 1: The CoC has a term of 20 years. The general licensee places a cask into service at the end of the 19th year VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 of the CoC term. The CoC is not renewed and expires at the end of the 20th year; that is 1 year after the general licensee loaded the cask. The term of a general license for a cask shall be for a storage period not to exceed the term certified by the cask’s CoC (i.e., for a CoC that is not renewed, the period of time commencing with the CoC effective date and ending with the CoC expiration date). Thus, in this scenario, the general license commences upon loading at the end of the 19th year and runs for 20 years (terminating 19 years after the date of the CoC expiration, giving a storage period of 20 years). Scenario 2: The initial CoC has a term of 20 years. The CoC is renewed (by rulemaking amending the appropriate entry in § 72.214) for 40 years. The general licensee places a cask into service at the end of the 39th year of the renewal term. The CoC is not renewed a second time and as such, expires 40 years after the effective date of the renewal amendment to § 72.214 (here, 1 year after the general licensee loaded the cask). The term of a general license for a cask shall be for a storage period not to exceed the term certified by the cask’s CoC (i.e., for a renewed CoC, that is the period of time commencing with the most recent CoC renewal date and ending with the CoC expiration date). Thus, in this scenario, the term of the general license for the cask would commence upon loading and terminate 40 years after loading (in this case, 39 years after expiration of the CoC, giving a storage period of 40 years). Scenario 3: The initial CoC has a term of 20 years. The CoC is then renewed for 40 years. The general licensee places a cask into service at the end of the 39th year of the renewal term. The CoC is then renewed a second time for an additional 40 years. In this case, the general license would run through the second renewal period. Thus, the general license for that cask would commence upon loading and terminate at the expiration of the CoC (giving a storage period of 41 years). Scenario 4: The initial CoC has a term of 20 years. The CoC is then renewed for 40 years. The general licensee places a cask into service at the end of the 39th year of the renewal term. The CoC is then renewed two more times, each additional CoC renewal term being for a 40-year period. In this case, the general license would run through both renewal periods. Thus, the general license for that cask would commence upon loading and terminate at the expiration of the CoC (giving a storage period of 81 years). Scenario 5: The initial CoC has a term of 20 years. The CoC is then renewed for PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 40 years. The CoC is then renewed a second and final time, but only for a 30 year period. The general licensee places a cask into service at the end of the 29th year of the final renewal term. In this scenario, the general license for that cask would be for a storage period not to exceed the term certified by the cask’s CoC (for a renewed CoC, that is the period of time commencing with the most recent CoC renewal date and ending with the CoC expiration date). Thus, in this scenario, the general license for this cask would commence upon loading and terminate 30 years after loading (in this case, 29 years after expiration of the CoC, giving a storage period of 30 years). In short, the general license term for any given cask will be, at a minimum, for a storage period not to exceed ‘‘the term certified by the cask’s CoC’’ (as that term is defined in § 72.3). The rationale for extending the general license through any CoC renewal term is twofold. First, the extension of the general license through a CoC renewal term is premised upon the licensee implementing all appropriate aging management requirements. Second, the NRC concluded that the occupational risks of taking a cask out of service and repackaging the spent fuel into another storage cask exceed the risks of leaving the spent fuel in the original cask. J. Are there possible conflicts that could arise for storage cask designs that are granted a term extension that are also approved for a different term limit as a transportation package? The Commission raised this issue in its SRM for SECY–06–0152, dated August 14, 2006. The NRC staff does not foresee any possible conflicts. The current regulations in part 72 encourage, but do not require, storage cask designs to have a compatible, approved transportation cask. So called ‘‘dual use’’ systems must be separately certified under the requirements in 10 CFR part 71 (transportation) and part 72 (storage). Typically, the only common item between these systems is the inner canister, which holds the spent fuel contents. Part 71 certificates for transportation packages are issued for a 5-year term whereas part 72 CoCs are issued for much longer periods (under the current regulations, all approved CoCs have 20-year terms; under this final rule, the CoC term is extended to a not to exceed 40-year term). For each transportation cask certified under 10 CFR part 71, the CoC specifies ‘‘approved contents.’’ The description of the approved contents for a spent fuel transportation package defines the acceptable fuel types and E:\FR\FM\16FER1.SGM 16FER1 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations characteristics and, typically, it is the condition of the fuel, not its age, that determines its acceptability. Spent fuel stored in casks, even for extended terms, is not expected to experience any significant degradation that would affect its acceptability to be shipped in a suitable transportation cask. The part 72 general design criteria require fuel retrievability (§ 72.122(l)) and for CoC applications, the design of the storage cask should consider, to the extent practicable, compatibility with removal of the stored spent fuel from a reactor site, transportation, and ultimate disposition by the Department of Energy (§ 72.236(m)). Based upon the NRCsupported INL research program and the Surry and H. B. Robinson ISFSI renewal applications, the NRC staff has concluded that typical spent fuel can be safely stored in casks without appreciable degradation. If the condition of spent fuel, or its storage canister, was believed to have degraded during extended storage such that it no longer met the criteria for approved contents, a licensee would have other alternatives for transport of that spent fuel. A new or modified approved transportation cask might be used, or the fuel might be repackaged, to place it in an acceptable configuration. erowe on DSK5CLS3C1PROD with RULES K. How does the NRC track cask expiration dates? Section 72.212(b)(2) of the final rule will require general licensees to register use of each cask with the Commission no later than 30 days after using that cask to store spent fuel. To register casks, licensees must submit their name and address, reactor license and docket numbers, the name and title of a person responsible for providing additional information concerning spent fuel storage under the general license, the cask certificate number, the amendment number, if applicable, cask model number, and the cask identification number. With this information, the Commission will know the loading and expiration dates of each cask. This information will also enable the NRC to schedule any necessary inspections and will permit the NRC to maintain an independent record of use for each cask. L. Who is responsible for applying for CoC renewals? The final rule retains the structure of the current rule, which emphasizes that the certificate holder (the cask vendor) applies for cask renewal. If the certificate holder chooses not to apply for the renewal of a particular cask design or is no longer in business, a licensee, a licensee’s representative, or VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 another certificate holder may apply for renewal in its place. If the applicant for CoC renewal seeks to fabricate this cask design, it must satisfy the applicable requirements of part 72, including establishment and maintenance of the requisite quality assurance (QA) program (general licensees may rely upon previously established part 50 or 71 QA programs if they meet the requirements of §§ 72.140 and 72.174). M. Does the NRC have a definition for ‘‘terms, conditions, and specifications’’ as they relate to the CoC? The NRC does not include a definition for ‘‘terms, conditions, and specifications’’ in the final rule because these words are generic in nature, and are used in other parts of the NRC’s regulations without definition. N. Can a licensee apply CoC amendments to previously loaded casks? This final rule amends § 72.212(b) to clarify that general licensees may apply changes authorized by a CoC amendment to a previously loaded cask provided that the licensee demonstrates, through a written evaluation, that the cask meets the terms and conditions of the subject CoC amendment (i.e., the loaded cask must conform to the CoC amendment codified by the NRC in § 72.214). O. May a general licensee implement only some of the authorized changes in a CoC amendment without prior NRC approval? If a general licensee elects to apply the changes authorized by a CoC amendment to a previously loaded cask, then the cask, after the changes have been applied, must conform to the terms and conditions (including the technical specifications) of the CoC amendment. Partial or selective application of some of the authorized changes, but not others, requires prior NRC approval (in this case, the general licensee would apply for an exemption). The basis for allowing licensees to apply the changes authorized by a CoC amendment to a previously loaded cask without prior approval from the NRC is that the cask will remain in an analyzed condition if, after the changes have been applied, it conforms to the terms and conditions of the CoC amendment. The NRC has previously stated, ‘‘a spent fuel storage cask will be relied on to provide safe confinement of radioactive material independent of a nuclear power reactor’s site, so long as conditions of the Certificate of Compliance are met’’ (54 FR 19381; May 5, 1989). However, partial or selective application of a CoC PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 8877 amendment’s changes could result in a cask that would be in an unanalyzed condition. In a related issue, the NRC agrees with an industry comment raised in response to the publication of the draft preliminary rule text (73 FR 45173; August 4, 2008). The draft preliminary rule text required that a general licensee ensure that once the changes authorized by a CoC amendment had been applied to a previously loaded cask, that the cask then ‘‘fully conforms’’ to the terms and conditions of the CoC amendment. The industry comment raised the concern that the phrase ‘‘fully conforms’’ was overly restrictive and requiring conformance with all the changes authorized by a CoC amendment would not be feasible or logical in certain instances, namely, in those cases where the amended CoC requirements do not apply to that particular general licensee site or ISFSI (e.g., requirements for pressurized water reactors (PWR) fuel at a boiling water reactor (BWR) plant). In light of this comment, the final rule language now requires that the cask, once CoC amendment changes have been applied, ‘‘conforms’’ to the terms and conditions of the CoC amendment. Thus, CoC amendment requirements for PWR fuel need not be met at a BWR plant. Similarly, if the CoC amendment includes changes to the Technical Specifications for loading, general licensees may have difficulty demonstrating that the previously loaded cask complies with the new loading requirements. As revised by this final rule, § 72.212(b)(5) will require general licensees to perform written evaluations prior to applying the changes authorized by an amended CoC to a previously loaded cask. If the evaluation indicates that the loading conditions under the initial or older CoC amendment would not affect the ability of the previously loaded cask to meet the storage or unloading requirements of the newer CoC amendment, then the cask would be considered as conforming with the terms and conditions of the newer CoC amendment without having to meet the new loading requirements. P. Do later CoC amendments encompass earlier CoC amendments? No, later CoC amendments do not encompass earlier amendments unless the language of the later CoC amendment expressly indicates otherwise. Generally, when the NRC reviews an amendment to a CoC, the NRC staff considers the changes associated with the amendment request only and limits its review to the E:\FR\FM\16FER1.SGM 16FER1 8878 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations bounding conditions of the analysis. Specific changes associated with earlier CoC amendments for previously loaded casks are not considered during the review process for a later amendment. Thus, depending on the nature of the changes, later amendments do not necessarily encompass earlier amendments and sometimes may be inconsistent with earlier amendments. erowe on DSK5CLS3C1PROD with RULES Q. Why can’t general licensees use the § 72.48 process to apply CoC amendment changes to previously loaded casks? The principal requirement of § 72.48 regarding changes to cask designs is that the desired changes do not result in a change in the terms, conditions, or specifications incorporated in the CoC. A previously loaded cask is bound by the terms, conditions, and technical specifications of the CoC applicable to that cask at the time the licensee loaded the cask. Thus, under § 72.48, a licensee may only make those cask design changes that do not result in a change to the terms, conditions, or specifications of the CoC under which the cask was loaded. The final rule will not amend § 72.48, but will amend § 72.212 by authorizing a general licensee to apply the changes authorized by a CoC amendment to a previously loaded cask, provided that after the changes have been applied, the cask conforms to the terms and conditions, including the technical specifications, of the CoC amendment. R. If a general licensee selects and purchases a cask fabricated under an earlier CoC amendment, but does not load the cask, can the general licensee adopt the most recent CoC amendment for the empty cask before loading it? Adoption of the most recent CoC amendment depends on the nature of the changes between the CoC amendment under which the cask system was fabricated and the most recent amendment. CoC amendments are routinely requested by cask manufacturers or vendors (also referred to as the certificate holders) to account for advances in cask design and technology. Some amendments will be associated with cask hardware changes. A cask system that was purchased under an older amendment may or may not be able to be modified to a cask system that meets the most recent amendment. As revised by this final rule, § 72.212(b)(5) will require that general licensees perform written evaluations demonstrating that the cask, once loaded with spent fuel, will conform to the terms, conditions and specifications of a CoC or an amended CoC listed in VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 § 72.214. In the case of an unloaded cask fabricated under the initial or earlier CoC amendment, the cask cannot be loaded under a later CoC amendment if the § 72.212(b)(5) evaluation shows that the cask, once loaded, will fail to meet the terms, conditions and specifications of the later CoC amendment. If the evaluation demonstrates that the terms, conditions and specifications of the later CoC amendment are met, then the cask can be loaded under the later CoC amendment. S. What are the NRC’s plans for providing guidance and examples of aging analyses and AMPs to licensees? The NRC has developed NUREG–1927 ‘‘Standard Review Plan for Renewal of Independent Spent Fuel Storage Installation Licenses and Dry Cask Storage System Certificates of Compliance.’’ This SRP provides guidance to the NRC staff in reviewing licensees’ programs for managing the effects of aging on spent fuel storage casks or ISFSI sites. Aging analyses and AMPs are two components of an overall program for managing the effects of aging. Because applicants will need to submit a TLAA and a description of their program to manage the effects of aging when applying for renewal of either CoCs or specific licenses under the final rule, this SRP will also assist potential applicants in identifying parameters to be included in a renewal application and measures necessary to ensure that the cask or ISFSI can be operated during the renewal period without undue risk to the public health and safety. The SRP will be published following the publication of this final rule. T. Could the NRC maintain the current paragraph designations of § 72.212(b)? The NRC understands the burden arising from changing the paragraph designations of a regulation. However, the NRC is rearranging the provisions of § 72.212(b) to better organize regulatory requirements. For example, the final rule will group recordkeeping requirements at the end of § 72.212(b) rather than dispersing them among other requirements, as is currently the case. The NRC’s intent for rearranging § 72.212(b) is to make this provision more user-friendly. These changes are documented in Table 1 located in Section IV (Item 4) of this document (Discussion of Final Amendments by Section under the discussion pertaining to § 72.212). PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 U. When are licensees required to submit cask registration letters? Under final § 72.212(b)(2), general licensees must submit a cask registration letter no later than 30 days after using that cask to store spent fuel. One registration letter may be submitted for a campaign that loads more than one cask, provided that the letter lists the cask certificate number, the amendment number, the cask model number, and the cask identification number of each cask covered by the campaign. In addition, under final § 72.212(b)(4), general licensees must submit a cask registration letter no later than 30 days after applying the changes authorized by an amended CoC to a previously loaded cask. One registration letter may be submitted for a campaign that applies CoC amendment changes to more than one cask, provided that the letter lists the cask certificate number, the amendment number to which the cask will conform, the cask model number, and the cask identification number of each cask covered by the campaign. V. If a CoC is not renewed, how long would general licensees have to remove casks of that design from service? For those cask storage systems for which renewals are not planned, general licensees should plan ahead to remove these cask storage systems from service at or before the termination of the general license (see the response to Question ‘‘I’’ above). Because users are most aware of the general cask schedule and the number of casks to be removed from service at their sites, users are in the best position to develop a reasonable schedule for the removal. W. When the NRC renews a CoC, are all amendments to that CoC simultaneously renewed as well? Section 72.214 lists one expiration date for each CoC. Amendments under a CoC may have different effective dates; however, they share the same certificate number and docket number. Therefore, when the NRC renews a CoC, all amendments to that CoC are renewed as well. X. If a general licensee applies for the renewal of a given CoC (assuming the certificate holder went out of business or chose not to apply for the renewal of a given CoC), and if the NRC approves the renewal of that CoC, is the renewed CoC available only to that general licensee or is it available to all general licensees? CoCs are generic designs and approved by rulemaking. The renewed CoC will be available to all persons who hold a general license under § 72.210. E:\FR\FM\16FER1.SGM 16FER1 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations Y. Can the requirements regarding TLAAs for CoC renewals be based upon a ‘‘current licensing basis’’ (CLB) patterned after 10 CFR part 54? The NRC does not believe that the part 54 CLB is the appropriate basis for TLAAs in support of CoC renewals. The NRC does not believe that it is appropriate for the CLB to be applied to cask CoC renewals, which are generic. The CLB is typically the set of NRC requirements applicable to a specific plant and a specific licensee’s written commitments for ensuring compliance with and operation within applicable NRC requirements, including the plant specific design basis (including all modifications and additions to regulatory commitments over the life of the license) that are docketed and in effect. Z. What is the status of the draft NRC Regulatory Issue Summary (RIS) 2007– 26 which was issued on January 14, 2008 (73 FR 2281)? The NRC decided not to finalize the draft RIS 2007–26 because § 72.212(b) provides a path forward for implementation of later CoC amendments to previously loaded casks. An Enforcement Guidance Memorandum (EGM), dated September 15, 2009, was issued in conjunction with the publication of the proposed rule to provide guidance to NRC inspectors for exercising enforcement discretion concerning deficiencies related to implementing changes, authorized by CoC amendments to previously loaded casks, that occurred prior to issuance of the EGM. erowe on DSK5CLS3C1PROD with RULES III. Summary and Analysis of Public Comments on the Proposed Rule This section presents a summary of the public comments received on the proposed rule and supporting documents, the NRC’s response to the comments, and changes made in the final rule and supporting documents as a result of these comments. The NRC received five comment letters on the proposed rule. These comments came from the Nuclear Energy Institute, the U.S. Department of Energy, Exelon Nuclear, Decommissioning Plant Coalition, and the Prairie Island Indian Community. Three of the commenters supported the new regulation, while two of the commenters expressed concern about the proposed regulation. The commenters opposed to the proposed regulation were primarily concerned about the increased license term extension from 20 to 40 years for specific ISFSI licensees. One of these VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 commenters also had questions about the environmental review process. The other commenters provided comments on different topics within the proposed rule, including the proposed CoC terms, the CoC renewal process, the CoC amendment process, TLAAs, and spent fuel storage in general. These commenters made observations about these topics and recommended areas within the proposed rule where the NRC could make improvements. Two commenters suggested revisions to the proposed rule language and the SOC. Copies of the public comments are available for review in the NRC Public Document Room, 11555 Rockville Pike, Rockville, MD 20852–2738. A review of the comments and the NRC responses follow: General Support Comment 1 A commenter agreed with the proposed amendments and stated that they are in the public interest and are consistent with scientific evidence. The commenter also noted that the proposed regulation would reduce the costs incurred by licensees and the NRC as a result of preparing and reviewing applications and exemption requests. The commenter stated that the proposed rule would provide the NRC and regulated entities with greater regulatory certainty. Response The NRC agrees with the comment. General Opposition Comment 2 A commenter suggested that the proposed revisions would negatively and directly impact their community and expressed opposition to extending specific ISFSI licenses by 40 years. The commenter also indicated that the proposed rule, along with the ‘‘scrapping’’ of Yucca Mountain, would lead to permanent spent fuel storage at nuclear power reactor sites. In addition, the commenter urged that the 20-year initial and renewal terms should remain unchanged. The commenter suggested that a 20-year term better protects the public because the casks are monitored more frequently. Response The NRC acknowledges the concerns raised by the commenter. The Commission believes there is reasonable assurance that spent fuel can be stored safely and without significant environmental impacts at ISFSIs during the extended license terms authorized by the final rule. This reasonable PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 8879 assurance is partly based on the technical data gained from an NRC supported research program and field data. Details are discussed in the response to Question ‘‘C’’ of the ‘‘Discussion’’ section of this document. Furthermore, this final rule would require all licensees to identify timedependent degradations of the ISFSI SSCs when they apply for license renewal. If any aging issues which could adversely affect SSCs are identified, the final rule requires the license renewal applicant to describe an AMP in its license renewal application. The AMP will address the prevention and mitigation of aging effects. The NRC staff will evaluate the AMP and will only approve the renewal application if the AMP is deemed adequate. An AMP would require licensees to monitor the casks and take other measures to ensure public health and safety. AMP requirements will be reflected in the terms and conditions of the renewed specific license, which are enforceable by NRC. The NRC will monitor the licensee’s compliance with the terms and conditions of the license through the NRC’s inspection program. The NRC concluded that, with appropriate aging management and maintenance programs, a license term up to 40 years is reasonable and provides adequate protection of public health and safety. Comment 3 A commenter stated that the proposed rule, ‘‘like the proposed revision of the Waste Confidence Rule,’’ validated the commenter’s earlier concerns raised during the initial licensing process for the ISFSI located near its Tribal boundary and ‘‘exposes the false assurances that the ISFSI is an interim or temporary solution.’’ The commenter added that the Commission’s position is to ‘‘simply streamline approvals for extending the term that spent fuel can be stored at either onsite or offsite ISFSIs.’’ The commenter suggested that ‘‘regulatory requirements should be further enhanced rather than relaxed.’’ Response The NRC has not made any regulatory or policy decision which states that the storage of spent fuel at ISFSIs obviates the need for a permanent repository of spent fuel and other high-level waste. The establishment of such a repository is a national policy decision and is beyond the scope of this rulemaking. The extension of specific license terms in § 72.42 does not relax any regulatory requirements. The rationale for extending the terms for specific ISFSI licenses, for both initial terms and E:\FR\FM\16FER1.SGM 16FER1 8880 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations renewals, is set forth in the responses to Questions ‘‘C’’, ‘‘D’’, and ‘‘F–H’’, in Section II of this document. The rule requires that any applicant for license renewal demonstrate the safety of the continued storage of spent fuel for the requested term through TLAAs and the establishment of an AMP. If the applicant demonstrates to the NRC appropriate aging management and maintenance programs, then the NRC has concluded that a renewal term up to 40 years is reasonable and provides adequate protection of public health and safety. CoC Terms and Renewal Process Comment 4 A commenter stated that the term ‘‘unloaded cask’’ in the fifth paragraph of Section II, ‘‘Discussion,’’ Question ‘‘E’’, of the proposed rule is unclear. The commenter asked whether the term ‘‘unloaded cask’’ is limited to a cask that has never been loaded or if it also includes a cask that has been used but subsequently unloaded of stored fuel. The commenter added that the review of a generic CoC renewal should not depend on whether or not a particular cask is unloaded. The commenter requested that the NRC delete the final sentence of the fifth paragraph of Section II, ‘‘Discussion,’’ Question ‘‘E.’’ Response In the context of the response to Question ‘‘E’’, the NRC considered the term ‘‘unloaded cask’’ to be either a cask that has never been loaded or one that was loaded and then subsequently unloaded. In any event, the NRC agrees with the comment. When a CoC is renewed by the NRC, it is the cask design that is being renewed. It does not matter whether the cask is loaded or not. Therefore, clarifying changes have been made to the response to Question ‘‘E’’, including the deletion of the sentence which contains the term ‘‘unloaded cask.’’ erowe on DSK5CLS3C1PROD with RULES Comment 5 Two commenters requested that NRC clarify Section II, ‘‘Discussion,’’ Questions ‘‘I’’ and ‘‘V’’ and Section III, ‘‘Discussion of Proposed Amendments by Section,’’ Item 4 and § 72.212(a)(3) of the proposed rule. These sections of the SOC and § 72.212(a)(3) address the relationship between the term of a general license, the CoC term and renewal, and the date an individual cask is loaded. One of the commenters stated that ‘‘[i]ndustry believes that each individual cask should be permitted to be operated for the full design life of the cask, VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 including the full renewal period.’’ The commenter stated that aging management requirements would be implemented during the renewal period. This commenter then provided two examples: the first, ‘‘a cask loaded under an active CoC with a 20-year initial term and not renewed should be permitted to be operated under a general license for 20 years from the date of initial use, no matter when that cask is placed into service;’’ and the second, ‘‘a cask loaded under an active CoC with a 20-year initial term and renewed for 40 years should be permitted to be operated under a general license for 60 years from the date of initial use, no matter when that cask is placed into service.’’ The commenter then asserted that each cask is fabricated to meet a specific design life and that the ‘‘successful renewal of the CoC extends that design life provided all design and maintenance parameters that were part of the renewal approval are met.’’ The commenter further asserts that the design life ‘‘does not begin for each individual cask until the cask is loaded, i.e., the cask is experiencing the conditions contemplated in design.’’ The commenter concluded that ‘‘forcing casks to be taken out of service at an arbitrary date would result in unnecessary fuel repackaging and occupational radiation exposition with no commensurate public health and safety benefit.’’ The second commenter made a similar comment, stating that the ‘‘cask life should be solely based on the qualification of the cask, and not on the CoC expiration date.’’ The commenter then suggested that ‘‘the NRC consider evaluating the lifespan of the fuel storage system based on date of loading (i.e., activation of the system) of the cask system in compliance with all applicable terms, conditions, and specification, and not based on other external factors.’’ Response The NRC agrees, in part, and disagrees, in part, with the comments. The part 72 regulations do not define the term ‘‘design life.’’ Rather, the part 72 regulatory scheme is based on licenses, specific and general, and the terms of those licenses. The general license term is premised upon the CoC in effect at the time the cask was placed into service (i.e., loaded with spent fuel and deployed onto the ISFSI pad). As explained in the response to Question ‘‘I’’ of Section II, the general license term, for loaded casks, will run through any consecutive CoC renewal terms as the occupational risk of unloading a cask and repackaging the spent fuel into PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 another storage cask exceeds the risk of keeping the spent fuel in the original cask. The NRC agrees with the first commenter’s statement regarding the implementation of aging management requirements during the renewal period. The NRC further agrees with the first commenter’s first example regarding a cask fabricated under a 20-year CoC term, which is not renewed. Under both the current regulation and the regulation as revised by this final rule, the general license term for such a cask would be 20 years, regardless of when during the 20-year CoC term the cask is placed into service. Of course, after the CoC expires, casks of that design could no longer be placed into service. The NRC disagrees with the second example and the commenter’s rationale to support that example. The commenter states ‘‘a cask loaded under an active CoC with a 20-year initial term and renewed for 40 years should be permitted to be operated under a general license for 60 years from the date of initial use, no matter when that cask is placed into service’’ (emphasis added). The NRC does not agree that successful renewals of the CoC cumulatively extend the general license term for that cask (the commenter uses the term ‘‘design life,’’ which the NRC assumes to be the equivalent of the general license term desired by the commenter). The commenter uses the example of a CoC that has an initial term of 20 years followed by a renewal term of 40 years. The commenter then asserts that the design life of the cask would be 60 years. Thus, under this reasoning, a cask placed into service the day before the renewed CoC expires could be in service for 60 years. Essentially, the commenter appears to be asserting that the regulatory scheme should allow cumulative terms, such that each successive renewal of the CoC adds to the design life of the cask, and thus, to the term of the general license. The intent of the amendments implemented by the final rule is that the use of a cask is determined by the general license term, which in turn is determined by the term specified in the applicable CoC in effect at the time the cask is placed into service; the general license term is not determined by adding all the successive CoC renewal terms to the initial CoC term. The term of the general license for any cask placed into service during a CoC renewal term is based upon the length of the renewal term (renewal date to expiration). Thus, if a CoC is renewed for 40 years and a cask fabricated under that CoC is placed into service during the 39th year of the renewal term, the E:\FR\FM\16FER1.SGM 16FER1 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations erowe on DSK5CLS3C1PROD with RULES general license for that cask would be 40 years. According to the commenter, if the initial term of the CoC was 20 years, and the CoC was then renewed twice, each time for 40 years, then a cask placed into service on the last day of the second renewal period would have a general license of 100 years (essentially, 100 years beyond the CoC expiration date). It is not the intent of the NRC to allow for such extended, cumulative license terms.1 Such an interpretation of the regulatory scheme implemented by this final rule is well beyond the regulatory norm and is not aligned with the stated purpose of this rulemaking, which was to extend specific license terms from not to exceed 20 years to not to exceed 40 years and then to make the terms of CoCs and general licenses equal with those of specific licenses. The NRC disagrees with the second commenter, who stated that ‘‘cask life should be solely based on the qualification of the cask, and not on the CoC expiration date.’’ In this regard, the NRC will allow for casks already in service, i.e., those already loaded prior to any given CoC renewal, to remain in service through any future renewal periods, given that the occupational hazards associated with unloading a cask and repackaging the spent fuel into another storage cask exceed the risks of leaving that fuel in the original cask. However, this is not the same as allowing an unloaded cask (i.e., either a new cask or one formerly loaded and then subsequently unloaded) to be placed into service for a cumulative term that is equal to the length of the initial term and all renewal terms. The intent of this final rule is that the general license term for any cask placed into service shall not be longer than the term certified by the then effective CoC, unless that CoC is renewed after that cask has been placed into service, in which case, the general license will terminate at the expiration of the CoC (i.e., at the end of the final CoC renewal term). Please see the response to Question ‘‘I’’ of this document for additional details, including examples of various general license scenarios. In response to these comments, this final rule amends § 72.212(a)(3) to include clarifying language regarding general license terms and similarly, 1 As background, see the response to Question 21 in the July 18, 1990 (55 FR 29186), final rule that promulgated subparts K and L of part 72. In particular, the NRC stated that ‘‘the 20-year storage period will also apply to new casks put into use after a Certificate of Compliance is reapproved.’’ Clearly, there was no intent that the storage period for a cask placed into service during the renewal term was to be for a term that was equal to the initial term plus the renewal term. VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 adds a definition of the phrase ‘‘the term certified by the cask’s Certificate of Compliance’’ to the part 72 definitions section, § 72.3. Comment 6 A commenter requested that the NRC clarify the QA program requirements for general licensees that seek to fabricate casks (as discussed in Section II, ‘‘Discussion,’’ Question ‘‘L’’ of the proposed rule). The commenter asked whether a general licensee that seeks to fabricate a cask under its part 50 QA program may apply its part 50 QA program as long as it governs part 72 activities. Response Section 72.140 sets forth the requirements of a part 72 QA program. Under § 72.140(d), a QA program previously approved by the Commission as satisfying the requirements of Appendix B to part 50 or subpart H of part 71 will be accepted as satisfying the requirements of § 72.140(b), provided that the general licensee or other applicant meets the recordkeeping requirements of § 72.174. In filing the description of the QA program required by § 72.140(c), a general licensee who seeks to fabricate casks under a renewed CoC must notify the NRC, in accordance with § 72.4, of its intent to apply its previously-approved QA program to part 72 activities. The notification shall identify the previously-approved QA program by date of submittal to the Commission, docket number, and date of Commission approval. Comment 7 A commenter suggested that the word ‘‘terms’’ in the phrase ‘‘terms, conditions, and specifications’’ may be confused with the word ‘‘term’’ as in the ‘‘term certified in the cask CoC.’’ The commenter requested that the NRC revise Section III, ‘‘Discussion of Proposed Amendments by Section,’’ Item 4 to address this issue. The commenter requested that the NRC add a definition to § 72.3 for the phrase ‘‘term certified by the cask’s Certificate of Compliance.’’ Response The NRC agrees that clarification is needed. The NRC added the following definition to § 72.3: ‘‘Term certified by the cask’s Certificate of Compliance, for the purposes of this part, means, for an initial CoC, the period of time commencing with the CoC effective date and ending with the CoC expiration date, and for a renewed CoC, the period of time commencing with the most PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 8881 recent CoC renewal date and ending with the CoC expiration date.’’ Comment 8 One commenter asked if a ‘‘cask user or user’s representative’’ renews a CoC, then would that user or user’s representative become the CoC holder and, as a result, obtain all CoC holder responsibilities. In particular, the commenter questioned whether the user or user’s representative would assume responsibility for cask Final Safety Analysis Report (FSAR) updating and reporting requirements under § 72.48. Response In the SOC for the July 18, 1990, final rule which promulgated subparts K and L of part 72, the NRC stated its expectation that the cask vendor, if still in business and fabricating the subject cask design, would apply for cask renewal (55 FR 29184; July 18, 1990). If the certificate holder is no longer in business or chooses not to apply for the renewal of a particular cask design, then a cask user or user’s representative (i.e., the licensee or licensee’s representative) could apply to renew a CoC. If approved by the NRC, the cask user or representative would then become the CoC holder. In this capacity, the cask user or representative absorbs all CoC holder responsibilities, such as cask FSAR updating and reporting requirements under § 72.48. CoC Amendment Process Comment 9 A commenter objected to a sentence in the first paragraph of Section II, ‘‘Discussion,’’ Question ‘‘O’’ that stated, ‘‘However, partial or selective application of a CoC amendment’s changes would result in a cask that would be in an unanalyzed condition.’’ The commenter asserted that this sentence was a ‘‘significant overstatement’’ as not all partial or selective application of a CoC amendment’s changes would result in the cask being in an unanalyzed condition. The commenter requested that the sentence be deleted or that the first instance of ‘‘would’’ be replaced with the word ‘‘could.’’ Response The NRC agrees with the comment that, depending on the nature of changes in the amendment, partial or selective application of a CoC amendment’s changes may not always result in the cask being in an unanalyzed condition. To minimize the possibility of the cask being in an unanalyzed condition, however, the general licensee is required to apply for E:\FR\FM\16FER1.SGM 16FER1 8882 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations an exemption in those cases where the general licensee seeks such a partial or selective application of the changes authorized by a later CoC amendment to a previously loaded cask. The NRC has revised the sentence in Section II, ‘‘Discussion,’’ Question ‘‘O’’ of this document as follows: ‘‘However, partial or selective application of a CoC amendment’s changes could result in a cask that would be in an unanalyzed condition.’’ Comment 10 A commenter suggested that the NRC should consider including in CoC amendments language addressing whether or not the CoC amendment encompasses all requirements of the initial CoC and previous amendments. The commenter asserted that such CoC amendment language would ‘‘significantly simplify’’ the adoption process for general licensees, ‘‘especially in cases where only the contents have changed and no cask hardware modifications are involved.’’ erowe on DSK5CLS3C1PROD with RULES Response The approach suggested by the commenter is not within the scope of this rulemaking because the commenter’s recommended language would be placed within the text of the CoC amendment, not the NRC regulations. Moreover, the NRC has considered a process that requires the application of every part 72 CoC amendment to include a basis which proposes the applicability of the proposed amendment to previously loaded casks. The NRC staff’s acceptance of the proposed applicability and its basis would then be documented in the CoC amendment and in the accompanying Safety Evaluation Report (SER). However, the NRC staff has concluded that conducting the requisite analyses to evaluate each prior CoC amendment in relation to the new amendment would impose more burdens on both the NRC and applicants as compared to the process in the final rule. Comment 11 With respect to Section II, ‘‘Discussion,’’ Question ‘‘W’’ of the proposed rule, a commenter asked whether, after the renewal of a CoC, subsequent amendments to that CoC continue the existing amendment numbering or if the numbering for these amendments ‘‘start over’’ as the first amendment against the renewed CoC. Response After a CoC is renewed, subsequent amendments to that CoC will continue VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 with the existing numbering. For example, if there are seven amendments under a CoC before renewal, the next amendment, under the same CoC after renewal, will be Amendment No. 8. Comment 12 A commenter provided comments as requested under Section II, ‘‘Discussion,’’ Question ‘‘AA’’ of the proposed rule. Question ‘‘AA’’ is not included in the SOC of this final rule because it was intended only to solicit comments on the particular items identified. Question ‘‘AA’’ solicited public comment on whether or not the evaluation required by proposed § 72.212(b)(5) should be reviewed and approved by the NRC. The commenter does not support NRC review of ‘‘evaluations performed pursuant to § 72.212(b)(5) to apply a later CoC amendment to previously loaded casks.’’ The commenter suggested that NRC review of these evaluations would be ‘‘inappropriate and contrary to the concept of a general licensee.’’ The commenter stated that the NRC approves CoC amendments and that § 72.212 evaluations, and revisions to these evaluations, ‘‘are reviewed by NRC under the inspection program, at NRC’s discretion.’’ Response The NRC agrees with the comment. The amendments implemented by this final rule do not require any prior NRC review or approval of the evaluations conducted by a general licensee pursuant to § 72.212(b)(5). After a general licensee has made the findings required by § 72.212(b)(5)(i)–(iii), it may apply the changes authorized by a later CoC amendment to a previously loaded cask. Of course, the NRC may review these evaluations through the NRC inspection program. Comment 13 A commenter described the proposed language in § 72.212(b)(7) that states, ‘‘and revise it to add a requirement to evaluate any changes to the site parameters determination and analyses required by § 72.212(b)(6),’’ as unnecessary and requested that the language of § 72.212(b)(7) be simplified. The commenter recommended that the NRC revise § 72.212(b)(7) from ‘‘paragraph (b)(5) of this section’’ to ‘‘paragraphs (b)(5) and (b)(6) of this section.’’ Response The NRC agrees with the comment that § 72.212(b)(7) could be clarified by modifying the first sentence. Therefore, PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 the NRC revised the first sentence of § 72.212(b)(7) as follows: ‘‘Evaluate any changes to the written evaluations required by paragraphs (b)(5) and (b)(6) of this section using the requirements of § 72.48(c).’’ Comment 14 A commenter stated that the proposed 30-day timeframes for licensees to notify the NRC of the initial use of a cask and the application of a later CoC amendment to a previously loaded cask will cause the licensee an ‘‘unnecessary administrative burden.’’ Specifically, the commenter argued that the proposed rule language would require licensees to send two separate notifications into the NRC: (1) For new casks, licensees would need to notify the NRC within 30 days of deployment; and (2) for previously loaded casks, licensees would need to notify the NRC within 30 days of applying the changes authorized by a CoC amendment to a previously loaded cask. The commenter noted that applying the changes authorized by a CoC amendment to previously loaded casks is usually part of a larger campaign that includes deploying new casks. The commenter stated that allowing ‘‘120 days for both notifications would allow general licensees to combine these two notifications into one, in most cases.’’ Response The NRC does not agree that the requirement to prepare two letters, one covering loading the new casks, and the second covering the application of the changes authorized by a later CoC amendment to previously loaded casks, is particularly burdensome. The NRC staff has concluded that the 30-day timeframe is a reasonable requirement. The NRC acknowledges that applying the changes authorized by a later CoC amendment to previously loaded casks may be connected to a cask loading campaign. If the general licensee is loading new casks fabricated under a given CoC amendment and the changes authorized by that CoC amendment are also applied to previously loaded casks at the same time as explained by the commenter, one registration letter may be sufficient for that whole campaign, provided that the letter lists the cask certificate number, the appropriate CoC amendment number, the cask model number, and the cask identification number of each cask, both new and previously loaded. The commenter states that the § 72.212(b)(5) report, which would cover both the loading of the new casks and the implementation of the changes to the previously loaded casks, would E:\FR\FM\16FER1.SGM 16FER1 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations be prepared well in advance of the loading campaign. Sections 72.212(b)(2) and (4), however, require the registration of the use of new casks and the application of changes authorized by a later CoC amendment to previously loaded casks, no later than 30 days after the action—not 30 days after the completion of the § 72.212(b)(5) report. Thus, even if the § 72.212(b)(5) evaluation report was completed well in advance of the campaign, the general licensee could time its actions such that changes to the previously loaded casks would be implemented at or near the same time that the new casks are deployed; and as such, have both parts of the campaign covered in one letter. In the event that the general licensee cannot time the loading of the new casks with the implementation of the changes authorized by the latter CoC amendment so as to have both actions covered by one 30-day letter, the licensee will be required to prepare two letters. Comment 15 A commenter requested that the NRC remove the word ‘‘all’’ from the first sentence of § 72.212(b)(4) to be consistent with the discussion provided in Section II, Question ‘‘O’’ of the proposed rule. Response The NRC agrees with the comment that, in order to be consistent, the word ‘‘all’’ should be removed in the first sentence of § 72.212(b)(4). The NRC revised § 72.212(b)(4) accordingly. erowe on DSK5CLS3C1PROD with RULES Comment 16 A commenter stated that § 72.212(b)(4) is unclear with regard to when the 30-day ‘‘clock’’ starts for licensees to notify the NRC. The commenter added that § 72.212(b)(4) is inconsistent with the wording used in § 72.212(b)(2). The commenter suggested the following language to replace the first sentence in § 72.212(b)(4): ‘‘Register each cask with the Nuclear Regulatory Commission no later than 30 days after applying the changes authorized by an amended CoC to a cask loaded under the initial or an earlier amended CoC.’’ Response The NRC disagrees with the comment. The 30-day clock starts after the application of changes authorized by the CoC amendment to the previously loaded cask (a cask loaded under the initial CoC or an earlier CoC amendment). The language suggested by the commenter is not sufficient because there is no direct nexus between the VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 phrase ‘‘each cask’’ with the phrase ‘‘the changes authorized by an amended CoC to a cask loaded under the initial or an earlier amended CoC.’’ The NRC concludes that the regulatory language of § 72.212(b)(4) is clear and will not be revised other than the deletion of the word ‘‘all’’ from the first sentence (as described in the response to Comment No. 15). Comment 17 A commenter stated that the proposed wording of § 72.212(b)(7) is unnecessarily complex and recommended the following language: ‘‘Changes to the written evaluations required by § 72.212(b)(5) of this section shall be reviewed in accordance with § 72.48(c), as applicable.’’ As an alternative, the commenter recommended that the NRC change the first word of this section of the proposed rule from ‘‘evaluate’’ to ‘‘review.’’ The commenter suggested this revision because some general licensees could interpret the word ‘‘evaluate’’ as requiring a full § 72.48 evaluation, regardless of the nature of the change to the document. Response The NRC disagrees with the comment. In response to Comment 13 the NRC revised § 72.212(b)(7) to read as follows: ‘‘Evaluate any changes to the written evaluations required by paragraphs (b)(5) and (b)(6) of this section using the requirements of § 72.48(c).’’ Both the language of the proposed rule and the above revised language follow the same logic and pattern as the regulatory language in effect before this final rule’s effective date (§ 72.212(b)(2)(ii) (2009)). The intent of this amendment was only to renumber the provision from § 72.212(b)(2)(ii) to § 72.212(b)(7) and make related clarifying changes (such as the reference to § 72.212(b)(6)). It is not the NRC’s intent to change the substantive meaning of this provision, and as such, the NRC does not agree with changing the word ‘‘evaluate’’ to ‘‘review.’’ Comment 18 A commenter stated that the addition of the phrase ‘‘and, for those casks to which the licensee has applied the changes of an amended CoC, the amended CoC’’ to § 72.212(b)(11) is unnecessary. The commenter suggested the following language instead: ‘‘Maintain a copy of the CoC and each amended CoC(s) applicable to casks loaded and deployed at the ISFSI, and the documents referenced in such Certificates for each cask model used for PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 8883 the storage of spent fuel until use of the cask model is discontinued.’’ Response The NRC disagrees with the comment because CoC amendments may have a different design basis from the initial CoC as well as each other. Consequently, it is necessary for general licensees to maintain the initial CoC (along with documents referenced in the initial CoC) for those casks operating under the terms and conditions of the initial CoC and for those casks operating under the terms and conditions of a given CoC amendment, to maintain that CoC amendment (along with documents referenced in the amended CoC). Comment 19 A commenter stated that the rule applies to facilities that have one or more operating reactors. The commenter expressed concern that the proposed regulation would create unneeded burdens for permanently shut-down reactor sites. The commenter suggested that the NRC modify the proposed language in § 72.212(b) to address this issue, but did not provide alternative language. Specifically, the commenter raised concerns about the application of changes authorized by a later CoC amendment to a cask loaded under the initial CoC amendment or an earlier CoC amendment thereto (a ‘‘previously loaded cask’’). Response Part 72 does not draw a distinction between an operating facility and a decommissioned facility. The part 72 regulations make a distinction between specific licenses and general licenses. Under § 72.210, a holder of a part 50 or 52 power reactor license holds a part 72 general license. Section 72.212 sets forth the conditions of a general license. If a decommissioned facility does not have an active part 50 or 52 license, it would then not have a part 72 general license; most likely, the facility would be operating under a specific part 72 license. The application of changes authorized by a CoC amendment to a previously loaded cask is not applicable to a specific license ISFSI, as those provisions of the final rule only apply to general licenses. In the case of a decommissioned facility that does operate under a part 50 or 52 license, and thus, has a part 72 general license, this rule would apply to the same extent as it would for any other part 50 or part 52 licensee. In this regard, there is no reason to treat a generally licensed ISFSI at a decommissioned site any differently E:\FR\FM\16FER1.SGM 16FER1 8884 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations than a generally licensed ISFSI at an active part 50 or 52 facility. The commenter may have assumed that this rule requires general licensees to apply the changes authorized by a CoC amendment to any previously loaded casks within the licensee’s control. This is not correct. Under this final rule, the application of the changes authorized by a CoC amendment to a previously loaded cask is at the discretion of the general licensee; unless otherwise directed by the NRC, the general licensee can choose to continue to use the cask in accordance with the CoC under which the cask was loaded. Time-Limited Aging Analyses and Aging Management Programs Comment 20 A commenter asked the NRC to clarify when aging management requirements apply to casks, such as a cask placed into service during the renewal term of a CoC. Response Aging management requirements only apply after the cask is in service for the length of time equal to the term certified by the cask’s initial CoC. For example, if the term of the initial CoC is 20 years, and a cask is placed into service at the end of the 19th year, then the general licensee would need to begin implementing the appropriate aging management requirements at the end of the 39th year, assuming the CoC was renewed. The appropriate time to initiate the aging management requirements will be identified in the NRC approval of a CoC renewal application. Specifically, the aging management requirements will be made conditions or specifications of the CoC and thus applicable to general licensees per § 72.212(b). The response to Question ‘‘H’’ in Section II was revised in light of this comment. erowe on DSK5CLS3C1PROD with RULES Comment 21 A commenter stated that the TLAAs for CoC renewals should be based on the CLB for the cask. The commenter described the CLB for the cask as the ‘‘original regulatory framework (i.e., the regulations, review guidance, and the associated SER(s)) under which the cask design, including amendments, was approved, plus any mandated or voluntary changes applied thereafter, as tracked by the CoC holder and discussed in the cask FSAR.’’ The commenter requested that the NRC clarify that at the time of renewal, the TLAAs do not have to adopt the latest regulatory framework unless that is part of the cask’s CLB. VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 Response The amendments to this final rule do not include a definition for CLB. The cask designs approved, both initially and for renewal, under the provisions of subpart L of part 72 are generic in nature. The CLB is appropriate for site specific licensing actions, not generic cask designs. The certificate holder must submit the TLAA when it applies for renewal of a given CoC (for a CoC renewal that encompasses CoC amendments that each may have different design basis, the certificate holder will have to address how the TLAA applies to each CoC amendment covered by the CoC). The TLAA is an implicit part of any new storage canister evaluation even though it is not explicitly identified in the existing regulations. This may be illustrated by consideration of operationally induced degradation. Specifically, applicants must consider operationally induced degradation and its effects as part of the new design engineering process. Such an evaluation becomes part of the applicants’ demonstration that a new cask design will perform as specified throughout its initial license period. For a renewal, the applicant bears the same burden of showing that the materials of construction (or components) will perform as required during the extended operational period. This extended operational life may not have been addressed in the original design consideration. Consequently, TLAAs (and other issues) were explicitly identified in the proposed regulations. The evaluation effort for renewal shifts its focus from material selection, as would be the case for a new design certification, to existing material condition/degradation assessment. The NRC staff determined that this subtle but important distinction be clearly identified. Comment 22 A commenter requested that the NRC clarify what is meant by the term ‘‘site aging issues,’’ as stated in Section II, ‘‘Discussion,’’ Question ‘‘AA’’ of the proposed rule. The commenter stated that CoC holders should identify the cask design features that are subject to age-related degradation and address them in a bounding manner for use of a cask beyond the initial CoC term. The commenter suggested that cask users review the CoC holder’s aging analysis and perform their own analyses to supplement or supersede the CoC holder’s generic analysis. PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 Response To clarify the NRC’s intent, the statement in the response to Section II, ‘‘Discussion,’’ Question ‘‘AA’’ of the proposed rule should have read: ‘‘Site specific aging issues’’ rather than ‘‘site aging issues.’’ The NRC asked whether the requirement for an AMP for CoC renewals should fully address possible aging issues related to a general licensee’s specific site (e.g., different environmental conditions). The NRC agrees with the comment that CoC holders should identify the cask design features that are subject to age-related degradation and address them in a bounding manner for use of a cask beyond the initial CoC term. The NRC further agrees that general licensees should review the CoC holder’s aging analysis and perform their own analyses to supplement or impose upon themselves a more restrictive analysis, but they cannot supersede the CoC holder’s analysis. Therefore, the general licensees’ analyses would address possible aging issues at their sites. Question ‘‘AA’’ is not included in the SOC of this final rule because it was intended only to solicit comments on the particular items identified. Comment 23 A commenter stated that AMP requirements, aging analyses, and other technical documents should be evaluated for a 20-year license renewal term instead of the proposed 40-year license renewal term. Response The basis for the NRC to increase specific ISFSI license terms from not to exceed 20 years to not to exceed 40 years is discussed in Question ‘‘C’’ of the ‘‘Discussion’’ section of the proposed rule. The NRC staff concluded that, with appropriate aging management and maintenance programs, license terms up to 40 years are reasonable and provide adequate protection of public health and safety. General Comments Regarding Spent Fuel Storage Comment 24 A commenter disagreed with the proposed rule’s allowance for unlimited specific license renewals. The commenter expressed concern that the ‘‘indefinite nature of the length of time’’ the NRC describes for storage at an ISFSI could create a ‘‘national landscape of ISFSIs’’ at decommissioned sites. The commenter added that indefinite storage of fuel at ISFSIs is in conflict with ‘‘the Commission’s long held policy that it E:\FR\FM\16FER1.SGM 16FER1 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations ‘does not intend to support storage of spent fuel for an indefinitely long period.’ ’’ The commenter also suggested that the NRC clearly state this policy in the Supplemental Information of the final rule document so that the ‘‘Commission’s intent is clear and consistent across its regulatory landscape, including its Waste Confidence decision.’’ The commenter stated that since 1998, the ‘‘federal government has had the obligation, by contract, to remove spent fuel and greater than class C waste from’’ nuclear power plant sites. The commenter urged the NRC to maintain its expectation ‘‘that these sites and future like sites not proliferate and linger as de facto longterm storage facilities.’’ Response Please see the response to Comment 3. Comment 25 A commenter agreed with the NRC that, with appropriate aging management and maintenance programs, 40-year licenses ‘‘are reasonable and protect public health and safety and the environment.’’ Environmental Review erowe on DSK5CLS3C1PROD with RULES Comment 26 A commenter stated that it is unclear how the requirements of the National Environmental Policy Act (NEPA) will be met. The commenter asked if licensees are required to submit an environmental report with their 40-year license renewal. The commenter concluded that license renewals should include a public environmental review process, such as a draft environmental assessment posted for public comment. Response The NRC implements its obligations under NEPA through its regulations in 10 CFR part 51. When a licensee applies for the renewal of a specific ISFSI license, the licensee is required to submit an environmental report under § 51.60(b)(1)(iii). Under §§ 51.26, 51.27, 51.28, 51.29, 51.73 and 51.74, if the NRC prepares an environmental impact statement (EIS), the most comprehensive of the NEPA analyses, public participation would be required (the above provisions concern publication of a notice of intent, scoping, a request for comments on the draft EIS, and distribution of the draft EIS). If the NRC staff does not prepare an EIS, as determined by NRC staff’s 15:27 Feb 15, 2011 Jkt 223001 Miscellaneous Items and Rule Language Revisions Comment 27 A commenter stated that, contrary to the first sentence of Section II, ‘‘Discussion,’’ Question ‘‘K’’ of the proposed rule, the current regulations do not require general licensees to maintain or submit a cask loading schedule to the NRC. The commenter requested that the NRC delete this language or revise the wording. Response Response The NRC acknowledges the commenter’s support for the not to exceed 40-year license terms. VerDate Mar<15>2010 environmental assessment (EA), it will issue a finding of no significant impact (FONSI). The NRC may issue the FONSI in draft form, which will include a request for public comments (§ 51.33). Issuing a draft FONSI is discretionary with the NRC. After a FONSI is finalized, it must be published in the Federal Register (§ 51.35). The intent of the response to Question ‘‘K’’ of the proposed rule was to inform readers that general licensees keep track of loading and expiration dates of each loaded cask. The NRC understands, however, that this is not an express regulatory requirement. As such, the NRC has rephrased Question ‘‘K’’ to ask how the NRC tracks cask expiration dates and has made clarifying changes to the response to Question ‘‘K.’’ The registration letters required by the regulations, as amended by this final rule, provide the NRC with the requisite information to track cask expiration dates. Comment 28 A commenter suggested that in Section II, ‘‘Discussion,’’ Question ‘‘T’’ of the proposed rule, the regulation should include a provision to permit licensees with existing § 72.212 reports to maintain the current regulatory numbering system and not have to revise these reports to reflect the redesignated sections within the proposed regulation. Response The NRC disagrees with the comment that a provision be added to the regulations. There is no requirement to revise past § 72.212 reports to reflect the redesignation of provisions in § 72.212(b) resulting from the amendments of this final rule. Past § 72.212 reports can remain formatted to the regulation that was in effect at the time the report was written. Section 72.212 reports written after the effective date of this final rule must conform to the redesignations in the final rule. PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 8885 Comment 29 A commenter stated that the phrase ‘‘no later than 30 days after using (loading) that cask’’ in Section II, ‘‘Discussion,’’ Question ‘‘U’’ of the proposed rule and § 72.212(b)(2) is too vague. The commenter suggested replacing the above language with the following: ‘‘placing the cask in storage at the ISFSI’’ to clearly establish a start date. Response In response to the commenter, the NRC is not going to change the rule text; this rule language has been in effect since 1990 without any controversy. Rather, the NRC is clarifying its response to Question ‘‘U’’ of this document by removing the term ‘‘loading’’ from the response. It is the NRC’s position that the 30-day clock starts when the loaded cask has been deployed in the ISFSI. Comment 30 A commenter stated that the phrase ‘‘casks of that design’’ as used in § 72.212(a)(3) is unclear. The commenter recommended that the phrase be clarified or revised to be consistent with the language used earlier in the section, ‘‘cask[s] fabricated under a Certificate of Compliance.’’ The commenter added that if the same meaning is not intended, then the NRC should define the two phrases in § 72.3. Response The NRC agrees with the comment that the terminology in § 72.212(a)(3) is not consistent; the NRC intended for the meaning to be the same in both instances. The NRC has revised § 72.212(a)(3) and it no longer contains the phrase ‘‘casks of that design.’’ Comment 31 A commenter asked whether ‘‘cask user or user’s representative,’’ as used in § 72.212(a)(3), is equivalent to the term ‘‘any licensee,’’ as used in § 72.240(a). The commenter concluded that if these terms are equivalent, then the NRC should use the same term in both sections of the rule. Response The final rule makes several revisions to § 72.212(a)(3), including deletion of the language referring to ‘‘any cask user or user’s representative.’’ The NRC staff concluded that this language was redundant of the language in § 72.240(a). This final rule also revises § 72.240(a) to allow a licensee, a licensee’s representative, or another certificate holder to apply for a cask renewal in the event that the original E:\FR\FM\16FER1.SGM 16FER1 8886 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations certificate holder is either no longer in business or chooses not to apply for renewal of the cask. Comment 32 A commenter requested that in § 72.212(b)(8), the NRC change ‘‘§ 50.59(c)(2)’’ to ‘‘§ 50.59(c).’’ The commenter suggested that the review of cask storage activities may require a full evaluation under § 50.59, which includes § 50.59(c)(1). Response The NRC agrees with the comment. Section 72.212(b)(8) has been changed accordingly. Comment 33 A commenter asked whether the phrase ‘‘a new protected area’’ in section § 72.212(b)(9)(iii) only applies to an ISFSI located outside a nuclear power plant’s protected area. The commenter requested that the NRC clarify this phrase. Response The phrase ‘‘a new protected area’’ in § 72.212(b)(9)(iii) applies only to an ISFSI that is physically separate from a reactor’s protected area. As a further point of clarification, all references to ‘‘new protected area(s)’’ in § 72.212(b)(9) apply only to an ISFSI physically separate from a reactor’s protected area. The NRC notes that the phrase ‘‘new protected area’’ has been part of the regulatory language after the rule was promulgated in 1990. The intent of this final rule is only to renumber § 72.212(b)(5)(iii) to § 72.212(b)(9)(iii). As additional background, the March 27, 2009, power reactor security rule (74 FR 13926, 13970) revised § 72.212(b)(5)(iii) to update the cross reference to the applicable part 73 section and add the word ‘‘personnel’’ before the word ‘‘searches.’’ Comment 34 A commenter stated that § 72.212(b)(12) uses the terms ‘‘cask supplier’’ and ‘‘cask vendor.’’ The commenter suggested that these terms are inconsistent with the term ‘‘CoC holder,’’ which the NRC uses elsewhere in the proposed rule. The commenter concluded that the terminology should be consistent throughout the rule. Response The NRC agrees with the comment that the terminology should be consistent. Therefore, the NRC has replaced the terms ‘‘cask supplier’’ and ‘‘cask vendor’’ in § 72.212(b)(12) with the term ‘‘CoC holder.’’ IV. Discussion of Final Amendments by Section 1. Section 72.3, Definitions The final rule adds definitions for ‘‘Aging management program,’’ ‘‘Term certified by the cask’s Certificate of Compliance,’’ and ‘‘Time-limited aging analyses.’’ 2. Section 72.24, Contents of application; Technical information The amendment to § 72.24(c) requires applicants seeking initial specific licenses or specific licensees seeking renewals to demonstrate in sufficient detail that the design of the ISFSI or monitored retrievable storage installation (MRS) is capable of performing the intended functions for the term requested in the application. 3. Section 72.42, Duration of license; renewal The amendment to § 72.42(a) extends the term for both an initial specific license and a license renewal from a term of not to exceed 20 years to a term not to exceed 40 years. The final rule also adds a requirement that specific licensees seeking renewals submit a TLAA and a description of the AMP. Any license renewal application will be required to include an analysis that considers the effects of aging on SSCs important to safety for the requested renewal term. The amendment to § 72.42(b) requires license renewal applications to include design bases information as documented in the most recently updated FSAR, as required by § 72.70. 4. Section 72.212, Conditions of general license issued under § 72.210 The final rule makes several changes to § 72.212. The final rule revises § 72.212(a)(3) to clarify the term of the general license and to match the term of the general license to the term of the applicable CoC. The final rule amendment also clarifies that the term of the general license runs through any renewal periods, unless otherwise specified in the CoC. In addition, the final rule also amends § 72.212(a)(3) to clarify the general license term for those casks placed into service during the final renewal term of a CoC or during the term of a CoC that was not renewed. The final rule amendment also states that, upon expiration of the general license, all casks subject to that general license must be removed from service. The final rule amends § 72.212(b) by redesignating and reorganizing the provisions of that section. The following table cross references the amended regulations with the regulations in effect immediately prior to the effective date of this final rule. Use of ‘‘modified’’ in Table 1 refers to a section whose content has been modified. Remaining table entries are either new provisions or provisions that have been redesignated but whose content is unchanged.

The final rule redesignates current § 72.212(b)(1)(i) as § 72.212(b)(1) and makes minor editorial changes to this provision. The final rule redesignates current § 72.212(b)(1)(ii) as § 72.212(b)(2) and further revises the provision to add a requirement that general licensees, when registering a cask no later than 30 days after loading, include the CoC amendment number, if applicable. The final rule adds a new provision, § 72.212(b)(3), that requires general licensees to ensure that each cask used by the general licensee conforms to the terms, conditions, and specifications of a CoC or an amended CoC listed in § 72.214. Partial or selective application of the terms, conditions, and specifications of a CoC or an amended CoC, without prior NRC approval, may result in a cask that is in an unanalyzed condition and is therefore, prohibited. The final rule adds a new provision, § 72.212(b)(4), that requires general licensees to register those previously loaded casks no later than 30 days after applying the changes authorized by an amended CoC. The final rule revises § 72.212(b)(2)(i) by requiring general licensees to prepare written evaluations before applying the changes authorized by an amended CoC to a previously loaded cask. Thus, the revised rule requires a written evaluation before loading the cask with spent fuel and an additional written evaluation before any changes authorized by a CoC amendment are applied to a previously loaded cask. The final rule redesignates current § 72.212(b)(2)(i) as § 72.212(b)(5). The final rule revises § 72.212(b)(2)(i) to state that the written evaluation must establish that the cask, once loaded with spent fuel or after changes authorized by an amended CoC have been applied, will conform to the terms, conditions, and specifications of a CoC or amended CoC listed in § 72.214, and redesignates current § 72.212(b)(2)(i)(A) as § 72.212(b)(5)(i). The final rule VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 redesignates current §§ 72.212(b)(2)(i)(B) and (C) as §§ 72.212(b)(5)(ii) and (iii), respectively. The final rule redesignates current § 72.212(b)(3) as § 72.212(b)(6) and revises this provision to add a reference to an amended CoC and to update the cross-reference to paragraph (b)(5). The final rule redesignates current § 72.212(b)(2)(ii) as § 72.212(b)(7) and revises this provision to add a requirement to evaluate any changes to the site parameters determination and analyses required by § 72.212(b)(6), using the requirements of § 72.48. The final rule redesignates current § 72.212(b)(4) as § 72.212(b)(8). The final rule revises current § 72.212(b)(5) to reflect changes made by the final rulemakings dated October 24, 2008, and March 27, 2009, and redesignates current §§ 72.212(b)(5) and (b)(6) as §§ 72.212(b)(9) and (b)(10), respectively (see ‘‘Note on October 24, 2008, and March 27, 2009, Final Rule Revisions to § 72.212(b)(5), and Redesignation of § 72.212(b)(5) to § 72.212(b)(9)’’ at the end of this Section IV, below). The final rule redesignates current § 72.212(b)(7) as § 72.212(b)(11) and revises this provision to add references to an amended CoC. The final rule also adds language to clarify that a licensee must comply with the technical specifications of the CoC, in addition to the terms and conditions of the CoC. Further, the revised language requires the licensee to comply with the terms, conditions, and specifications of the amended CoC for those casks to which the licensee has applied the changes of an amended CoC. The revised language further provides that licensees must also comply with the requirements of any AMP put into effect as a condition of the NRC approving a CoC renewal application. The final rule redesignates current §§ 72.212(b)(8)(i), (b)(9), and (b)(10) as §§ 72.212(b)(12), (b)(13), and (b)(14), respectively.

Section 72.230, Procedures for spent fuel storage cask submittals The final rule revises § 72.230(b) by adding language that establishes the term for a period not to exceed 40 years. The final rule further amends § 72.230(b) by replacing the words ‘‘for a period of at least 20 years’’ with ‘‘the term proposed in the application.’’ 6. Section 72.236, Specific requirements for spent fuel storage cask approval and fabrication The final rule revises § 72.236(g) by adding language that requires spent fuel storage casks to be designed to store spent fuel safely for the term proposed in the application, eliminating the current language that requires the cask design to store spent fuel safely for a minimum of 20 years. 7. Section 72.238, Issuance of an NRC Certificate of Compliance The final rule revises § 72.238 by adding language that establishes the term for a CoC to be ‘‘not to exceed 40 years.’’ 8. Section 72.240, Conditions for spent fuel storage cask renewal The final rule revises the heading of § 72.240 and the language of §§ 72.240(a), (b), and (d) by replacing the word ‘‘reapproval’’ with ‘‘renewal.’’ The final rule further revises § 72.240(a) to establish that the CoC renewal term shall be ‘‘not to exceed 40 years.’’ The final rule also revises § 72.240(a) to clarify that in the event that a certificate holder does not apply for a CoC renewal, any general licensee that uses this cask model under the general license issued under § 72.210, any licensee’s representative, or another E:\FR\FM\16FER1.SGM 16FER1 erowe on DSK5CLS3C1PROD with RULES 8888 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations certificate holder may apply for renewal of the CoC. The final rule adds a new § 72.240(c) to require the safety analysis report accompanying the renewal application to include design bases information as documented in the most recently updated FSAR, a TLAA of SSCs important to safety, and a description of the program for management of issues associated with aging that could adversely affect structures, systems, and components important to safety. The final rule redesignates § 72.240(c) as § 72.240(d) and revises this provision to add a requirement that any CoC renewal application must demonstrate compliance with the QA provisions of subpart G of part 72. The final rule also revises the last sentence of the provision to improve its readability. The final rule adds a new § 72.240(e) that states the NRC may, as part of the approval of a CoC renewal application, revise the terms, conditions, and specifications of the CoC to require that the licensee implement an AMP. Note on October 24, 2008, and March 27, 2009, Final Rule Revisions to § 72.212(b)(5), and Redesignation of § 72.212(b)(5) to § 72.212(b)(9): This final rule redesignates § 72.212(b)(5) as § 72.212(b)(9). On October 24, 2008 (73 FR 63545, 63573), the NRC issued a final rule, ‘‘Protection of Safeguards Information,’’ that revised § 72.212 by adding a new § 72.212(b)(5)(v) and redesignated the existing § 72.212(b)(5)(v) as § 72.212(b)(5)(vi). The new § 72.212(b)(5)(v) added language requiring a general licensee to ‘‘protect Safeguards Information against unauthorized disclosure in accordance with the requirements of § 73.21 and the requirements of § 73.22 or § 73.23 of this chapter, as applicable.’’ The redesignated § 72.212(b)(5)(vi) was otherwise unchanged and continued to require ‘‘for the purpose of this general license, the licensee is exempt from §§ 73.55(h)(4)(iii)(A) and 73.55(h)(5) of this chapter.’’ These two cross referenced paragraphs dealt with reactor security requirements to (1) neutralize threats by interposing armed security personnel between the adversaries and reactor vital areas and (2) use force to prevent or impede attempted acts of theft of special nuclear material or radiological sabotage; and the NRC has historically not applied these requirements to ISFSI general licensees. On March 27, 2009 (74 FR 13925, 13970), the NRC published a final rule, ‘‘Power Reactor Security Requirements,’’ which included a conforming change to the security requirements contained in § 72.212(b)(5)(ii)–(v). The changes to VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 § 72.212(b)(5)(ii)–(v) in the March 2009 final rule were intended to clarify these regulations to better use plain language and to update the exemption cross references to the reactor security regulations contained in § 73.55, due to the extensive revision of § 73.55. In the March 2009 final rule, the NRC revised § 72.212(b)(5)(v) to update the exemption language to read ‘‘[f]or the purpose of this general license, the licensee is exempt from requirements to interdict and neutralize threats in § 73.55 of this chapter.’’ However, the amendatory language in the 2009 final rule (74 FR 13970, Item 8) which read ‘‘[i]n § 72.212, paragraphs (b)(5)(ii), (b)(5)(iii), (b)(5)(iv), and (b)(5)(v) are revised to read as follows:’’ should instead have read ‘‘[i]n § 72.212, paragraphs (b)(5)(ii), (b)(5)(iii), (b)(5)(iv), and (b)(5)(vi) are revised to read as follows:’’ (emphasis added). Consequently, the NRC staff in developing the March 2009 final rule both (1) unintentionally eliminated language that had been added by the Commission in the October 2008 final rule that required general ISFSI licensees to protect Safeguards Information; and (2) unintentionally retained the incorrect exemption language in § 72.212(b)(5)(vi) (referring to §§ 73.55(h)(4)(iii)(A) and 73.55(h)(5)). The provision designated as § 72.212(b)(5)(v) by the March 2009 final rule was intended to replace § 72.212(b)(5)(vi), but did not accomplish that because of the above described mistake in the amendatory language. Accordingly, to correct these errors, this final rule removes § 72.212(b)(5)(vi) (which was put in place by the October 24, 2008, final rule) and reinstates the provision added by the October 24, 2008, rule and then deleted by the March 27, 2009, rule, as a new § 72.212(b)(9)(vi). The remaining provisions of § 72.212(b)(5) are redesignated from § 72.212(b)(5)(i)–(v) to § 72.212(b)(9)(i)–(v). V. Criminal Penalties For the purpose of Section 223 of the Atomic Energy Act (AEA), the Commission is amending 10 CFR part 72 under one or more of Sections 161b, 161i, or 161o of the AEA. Willful violations of the rule would be subject to criminal enforcement. VI. Agreement State Compatibility Under the ‘‘Policy Statement on Adequacy and Compatibility of Agreement State Programs’’ approved by the Commission on June 30, 1997, and published in the Federal Register (62 FR 46517; September 3, 1997), this rule PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 is classified as Compatibility Category ‘‘NRC.’’ Compatibility is not required for Category ‘‘NRC’’ regulations. The NRC program elements in this category are those that relate directly to areas of regulation reserved to the NRC by the AEA, as amended, or the provisions of Title 10 of the CFR. Although an Agreement State may not adopt program elements reserved to NRC, it may wish to inform its licensees of certain requirements via a mechanism that is consistent with the particular State’s administrative procedure laws but does not confer regulatory authority on the State. VII. Voluntary Consensus Standards The National Technology Transfer Act of 1995 (Pub. L. 104–113) requires that Federal agencies use technical standards that are developed or adopted by voluntary consensus standards bodies unless using such a standard is inconsistent with applicable law or otherwise impractical. In this final rule, the NRC is clarifying the terms for spent fuel storage cask designs, or CoCs, and ISFSI licenses. In addition, the final action also allows part 72 general licensees to implement changes authorized by an amended CoC to a cask loaded under the initial CoC or an earlier amended CoC (a ‘‘previously loaded cask’’). This action does not constitute the establishment of a standard that establishes generally applicable requirements. For this reason, the NRC concludes that the Act does not apply to this final rule. VIII. Finding of No Significant Environmental Impact: Availability The Commission has determined under the National Environmental Policy Act of 1969, as amended, and the Commission’s regulations in subpart A of 10 CFR part 51, not to prepare an environmental impact statement for this final rule because the Commission has concluded on the basis of an environmental assessment that this final rule would not be a major Federal action significantly affecting the quality of the human environment. The NRC has prepared an environmental assessment and, on the basis of this environmental assessment, has made a finding of no significant impact. The amendments are procedural in nature whereby extended license and CoC terms and the implementation of CoC amendments to previously loaded casks could be achieved by exemptions under the current regulations. They will not have a significant incremental effect on the environment. Therefore, the NRC has determined that an environmental E:\FR\FM\16FER1.SGM 16FER1 Federal Register / Vol. 76, No. 32 / Wednesday, February 16, 2011 / Rules and Regulations impact statement is not necessary for this rulemaking. The determination of this environmental assessment is that there will be no significant impact to the public from this action. This conclusion was published in the environmental assessment that was made available for comment for 75 days after publication of the proposed rule at the NRC Public Document Room, Room O1–F21, 11555 Rockville Pike, Rockville, MD 20852. No comments were received on the content of the environmental assessment. The environmental assessment is also available in ADAMS, accession number ML100710441. IX. Paperwork Reduction Act Statement This rule contains new or amended information collection requirements that are subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). These requirements were approved by the Office of Management and Budget, control number 3150–0132. The burden to the public for these information collections is estimated to average ¥0.33 hours per response (or a reduction of approximately 1 hour for every three responses). Send comments on any aspect of these information collections, including suggestions for reducing the burden, to the Information Services Branch (T–5 F52), U.S. Nuclear Regulatory Commission, Washington, DC 20555– 0001, or by Internet electronic mail to Infocollects.Resource@NRC.gov and to the Desk Officer, Christine Kymn, Office of Information and Regulatory Affairs, NEOB–10202, (3150–0132), Office of Management and Budget, Washington, DC 20503. You may also e-mail comments to Christine_J_Kymn@omb.eop.gov or comment by telephone at 202–395– 4638. erowe on DSK5CLS3C1PROD with RULES Public Protection Notification The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid OMB control number. X. Regulatory Analysis The Commission has prepared a regulatory analysis on this regulation. The analysis examines the costs and benefits of the alternatives considered by the Commission. The analysis is available in the NRC Public Document Room, Room O1–F21, 11555 Rockville Pike, Rockville, MD 20852, and in VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 ADAMS, Accession Number ML100710139. As part of the proposed rule, the NRC sought public comments on the draft regulatory analysis. The NRC did not receive any comments that addressed the regulatory analysis. XI. Regulatory Flexibility Certification Under the Regulatory Flexibility Act of 1980 (5 U.S.C. 605(b)), the Commission certifies that this rule does not have a significant economic impact on a substantial number of small entities. The majority of companies that own these plants do not fall within the scope of the definition of ‘‘small entities’’ set forth in the Regulatory Flexibility Act or the size standards established by the NRC (10 CFR 2.810). XII. Backfit Analysis The NRC has determined that the backfit rule (§§ 50.109, 72.62, and the finality provisions of 10 CFR part 52) does not apply to this final rule because these amendments do not involve any provisions that would impose backfits as defined in 10 CFR chapter I. These amendments do not require the addition, elimination, or modification of structures, systems, or components of an ISFSI or of the procedures or organization required to operate an ISFSI. Therefore, a backfit analysis is not required. XIII. Congressional Review Act Under the Congressional Review Act of 1996, the NRC has determined that this action is not a major rule and has verified this determination with the Office of Information and Regulatory Affairs of OMB.

SUPPLEMENTARY INFORMATION: DEPARTMENT OF TRANSPORTATION Background Federal Aviation Administration The FAA periodically issues temporary regulations in 14 CFR called Special Federal Aviation Regulations (SFARs). These SFARs are typically necessary for a finite period of time, and usually specify an expiration date within the regulatory text. Additionally, certain subparts have specified expiration dates within the regulatory text. Currently, 14 CFR contains several SFARs, subparts, and sections that have become unnecessary or have expiration dates that have passed. To maintain an accurate body of regulations, we are removing and/or amending SFAR Nos. 36, 80, 92–5, 93, 98, 101–1; Subparts J and M of part 21; Subpart B of part 93; §§ 91.146(b), 121.360, 135.153, 183.61(a)(1), 183.63, and corresponding references.

Under the Administrative Procedure Act, an agency doesn’t have to issue a notice of proposed rulemaking when the agency for good cause finds that public notice and procedure are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ See 5 U.S.C. 553(b). Because this technical amendment simply removes obsolete regulations and references, we find that publishing the changes for public notice and comment is unnecessary. VerDate Mar<15>2010 15:27 Feb 15, 2011 Jkt 223001 The Administrative Procedure Act also states that an agency must publish a substantive rule not less than 30 days before its effective date, except as otherwise provided by the agency for good cause. See 5 U.S.C. 553(d). We find that this technical amendment imposes no additional burden or requirement on the regulated industry, and is not substantive in nature.

License and Certificate of Compliance Terms

AGENCY: Nuclear Regulatory Commission.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission)
is amending its regulations that govern licensing requirements for the
independent storage of spent nuclear fuel. These amendments include
changes that enhance the effectiveness and efficiency of the licensing
process for spent nuclear fuel storage. Specifically, they extend and
clarify the term limits for storage cask Certificates of Compliance
(CoCs) and independent spent fuel storage installation (ISFSI) specific
licenses. The amendments also provide consistency between the general
and specific ISFSI license requirements, and allow general licensees
subject to these regulations to implement changes authorized by an
amended CoC to a cask loaded under the initial CoC or an earlier
amended CoC (a ``previously loaded cask'').

DATES: Effective Date: This final rule is effective on May 17, 2011.

I. Background

On April 29, 2002, the Virginia Power and Electric Company
(Dominion) submitted an application to renew Special Nuclear Materials
(SNM) License SNM-2501 for the Surry ISFSI. SNM-2501 authorizes the
storage of spent nuclear fuel in casks at the Surry Nuclear Power
Plant. In the renewal application, Dominion requested an exemption from
the 20-year license renewal term specified in 10 CFR 72.42(a) and
sought approval for a 40-year license renewal term. Similarly, on
February 27, 2004, Progress Energy Carolinas, Inc. submitted an
application for the renewal of H. B. Robinson's ISFSI license which
requested an exemption from the provisions of Sec. 72.42(a), so that
the license renewal period for the H. B. Robinson's ISFSI could be
extended from 20 to 40 years.
The NRC staff determined the 40-year renewal exemption request to
be a policy decision, not a technical one, because the safety
evaluation indicated sufficient technical information had been provided
in the application to grant the 40-year renewal period. As a result, a
Commission paper (SECY-04-0175) entitled, ``Options for Addressing the
Surry Independent Spent Fuel Storage Installation License-Renewal
Period Exemption Request,'' was submitted on September 28, 2004, to
request Commission approval of the Surry 40-year renewal exemption
request.
On November 29, 2004, the Commission issued a Staff Requirements
Memorandum (SRM) for SECY-04-0175, which authorized the NRC staff to
approve a 40-year license renewal term for the Surry ISFSI, with
appropriate license conditions to manage the effects of aging. The SRM
further directed the NRC staff to: (1) Initiate a program to review the
technical basis for future rulemaking; (2) provide recommendations on
the license term for part 72 CoCs for spent nuclear fuel cask storage
systems; and (3) apply the Commission-approved guidance for part 72
renewals to future specific license exemption requests without further
Commission approval. In response to this direction, the staff submitted
a Commission paper (SECY-06-0152) entitled, ``Title 10 Code of Federal
Regulations part 72 License and Certificate of Compliance Terms,'' on
July 7, 2006, to recommend the scope of rulemaking.
In an SRM, dated August 14, 2006, the Commission authorized the
staff to proceed with rulemaking proposals described in SECY-06-0152.
In addition, the Commission specifically directed the staff to address
the following points in the rulemaking: (1) Clarify the start of the
20-year term limit for cask designs approved under general license
provisions; (2) identify whether the cask vendor or licensee is
responsible for applying for the CoC renewals; (3) discuss possible
conflicts that could arise for storage cask designs that are granted a
license term extension and that have been approved for transport with a
different license term; (4) discuss how the cask expiration dates are
tracked at each general license site so that it is clearly understood
when the CoC for each cask design must be renewed; and (5) clarify the
difference between CoC ``approval'' and ``renewal.''
As this rulemaking commenced, the NRC staff identified a related
issue regarding its approval of Amendment 4 to CoC 72-1026, which
revised cask monitoring and surveillance requirements for the BNG Fuel
Solutions W-150 storage cask. Subsequent to the approval, the
certificate holder requested guidance from the NRC on the
implementation of the changes authorized by the CoC amendment to
previously loaded casks. In addition to this request, the NRC staff
became aware of the belief among some general licensees that changes
authorized by CoC amendments can be applied to previously loaded casks
without prior NRC approval, if an analysis under Sec. 72.48 is
performed.
The NRC staff determined that under the current regulations,
changes authorized by CoC amendments cannot be applied to previously
loaded casks without express NRC approval, if such change results in a
change to the terms or conditions of the CoC under which the cask was
loaded. A previously loaded cask is bound by the terms and conditions
(including the technical specifications) of the CoC applicable to that
cask when the licensee loaded the cask. Therefore, under the current
regulations, general licensees that want to apply changes approved by a
CoC amendment to a previously loaded cask must request an exemption
from the

[[Page 8874]]

NRC if these changes alter the terms or conditions of the CoC under
which that cask was loaded.
In the SRM for COMSECY-07-0032, dated December 12, 2007, the
Commission stated that it did not object to the staff expanding the
scope of the proposed rulemaking to include the following two issues:
(1) To extend the terms of specific ISFSI licenses, for both initial
and renewal terms, to not to exceed 40 years; and (2) to allow a
general licensee to apply changes for a CoC amendment to a previously
loaded cask without express NRC approval, while still ensuring that
this action protects public health and safety.
In the August 14, 2006, SRM for SECY-06-0152, the Commission
directed the NRC staff to be as transparent as possible in developing
the proposed rule package, including making draft text available for
comment to stakeholders, and holding public meetings, if necessary,
before formal submission of the proposed rule to the Commission. In
response, the NRC staff held public meetings on November 7, 2006, and
February 29, 2008, to discuss the technical basis of the rulemaking
with stakeholders. In addition, on August 4, 2008, the NRC staff made
preliminary draft rule text available for comment to stakeholders on
Regulations.gov (Docket ID NRC-2008-0361). The only external
stakeholders that submitted comments were the Nuclear Energy Institute
and Florida Power and Light. The comments generally supported the
rulemaking. The ``Discussion'' section of this document includes NRC
responses to significant stakeholder comments.
The NRC published the proposed rule, ``License and Certificate of
Compliance Terms'' in the Federal Register on September 15, 2009 (74 FR
47126), for public comment. The NRC received five comment letters on
the proposed rule. These comments and the NRC responses are discussed
in Section III of this document, ``Summary and Analysis of Public
Comments on the Proposed Rule.''

II. Discussion

A. What action is the NRC taking, and why?

The NRC is revising part 72 requirements for specific and general
ISFSI licensees and part 72 requirements pertaining to CoCs to enhance
the effectiveness and efficiency of the licensing process.
For specific ISFSI licenses, the Commission is codifying a
technical approach consistent with that applied in granting the 40-year
exemptions for the Surry and H. B. Robinson specific ISFSI license
renewals, so that all specific ISFSI licensees will have the
flexibility to request initial and renewal terms not to exceed 40 years
while ensuring safe and secure storage of spent nuclear fuel.
For CoCs, the Commission is also allowing the flexibility for CoC
applicants and CoC holders to request, respectively, initial terms and
renewal terms not to exceed 40 years. The response to Question ``C'' of
this section discusses the technical basis for this change. Under this
change, applicants and CoC holders will be required to demonstrate that
design and operational programs are suitable for the requested term.
The NRC staff has developed a standard review plan (SRP) for renewal
applications. The final rule amendments also clarify the term (length)
of the general license, particularly as the general license term
relates to CoC renewals (see the response to Question ``I'' of this
section for further detail).
For both specific licenses and CoCs, the final rule adds a
requirement that renewal applicants must provide TLAAs and a
description of an AMP (see the responses to Questions ``F'', ``G'', and
``H'') to ensure that storage casks will perform as designed under
extended license terms.
The NRC is replacing the term ``reapproval,'' which is used to
describe the process of extending the CoC terms, to ``renewal'' for
consistency with specific license terminology. Question ``E'' of this
section discusses the rationale for this change.
The final rule will also allow general licensees to implement
changes authorized by a CoC amendment to a previously loaded cask,
provided that the loaded cask then conforms to the CoC amendment
codified by the NRC in Sec. 72.214 and thus, continues to ensure the
safe and secure storage of spent nuclear fuel. Question ``N'' of this
section discusses the rationale for this change.

B. Whom does this action affect?

The final rule will affect part 72 specific and general licensees
and CoC holders and applicants for a CoC.

C. Why is the NRC increasing initial terms and renewal terms for
specific ISFSI licenses from not to exceed 20 years to not to exceed 40
years?

The NRC is amending Sec. 72.42 to increase the initial terms and
renewal terms for specific ISFSI licenses from not to exceed 20 years
to not to exceed 40 years. This increase is consistent with the NRC
staff's findings regarding the safety of spent nuclear fuel storage, as
documented in the renewal exemptions issued to the Surry and H. B.
Robinson ISFSIs. During the review for the Surry and H. B. Robinson
renewal applications, the NRC staff evaluated the technical data
resulting from an NRC-supported research program at the Idaho National
Laboratory (INL), formerly Idaho National Engineering and Environmental
Laboratory, and also considered experience with spent fuel storage
casks used at Surry. Under the INL research program, INL opened a
storage cask after the fuel had been stored for approximately 15 years.
At Surry, several casks were also opened after less than 15 years of
storage as a result of some faulty weather covers, which were
corrected. Summaries of the findings regarding the condition of the
fuel and cask components follow:
(1) Cladding creep is a time-dependent change in the dimension of
the cladding resulting from high temperature and stress. It was
considered as a potential degradation mechanism during storage.
Confirmatory inspection of the spent fuel stored at INL verified that
no cladding creep had occurred. The spent fuel in storage at Surry also
supports this finding. The NRC staff expects very little to no fuel
degradation at the end of an extended licensing period. The established
limits for cladding temperature during storage accompanied by a
continually decreasing level of cladding stress and temperature,
further remove creep as a degradation mechanism. Assessment of these
factors indicates that cladding creep will not be an issue during a 40
year term.
(2) The NRC staff also expects limited degradation of other
internal components because there are no significant corrosive
influences in the inert environment, either for the fuel or for other
components. The INL inspection verified that there was no indication of
corrosion for any internal canister components. The NRC staff has also
concluded that radiation levels are too low to significantly alter the
properties of the metals for any storage canister components.
(3) The other external components of the storage systems (which are
exposed to weathering effects) would already be covered by an
inspection and corrective action program, or routine maintenance, to
ensure that any degradation will be identified and assessed for its
importance to safety, and will be addressed through corrective actions
to ensure continued safe operation of the storage system.
Based on these findings, the Commission concludes that, with

[[Page 8875]]

appropriate aging management and maintenance programs, license terms
not to exceed 40 years are reasonable and protect public health and
safety.

D. Can applicants apply for an initial term or renewal term greater
than 40 years?

This final rule amends Sec. 72.42 by extending the term allowed
for specific ISFSI licenses from not to exceed 20 years to not to
exceed 40 years. This extension applies to both the initial terms and
renewal terms. Any request for a term greater than 40 years would be
processed as an exemption under Sec. 72.7. The NRC does not plan to
ordinarily grant license term requests for greater than 40 years. As
discussed in Question ``C'' of this section, the NRC believes that
terms that do not exceed 40 years are reasonable and provide adequate
protection of public health and safety, if the applicant demonstrates
to the NRC appropriate aging management and maintenance programs.
If an applicant requests a specific license term greater than 40
years, that applicant would have to provide information on the long-
term material degradation of spent fuel storage casks, as well as
associated aging management activities, to justify safe operation
during such an extended period, and the NRC would need to evaluate this
information.

E. Why is the NRC changing the word ``reapproval'' to ``renewal''?

The NRC is changing the word ``reapproval'' to ``renewal'' in the
final rule to be consistent with the terminology used in other license
requirements under part 72. Currently, Sec. 72.240 uses ``reapproval''
to describe the process of extending the terms of CoCs. However, this
terminology differs from other sections in part 72. For example, Sec.
72.42 uses the word ``renewal'' to define the process for extending the
term of specific ISFSI licenses, and Sec. 72.212(a)(3) uses
``renewals'' to define the process for the continued use of storage
casks of a particular design under a general license. Although
``reapproval'' and ``renewal'' are similar words, they are subject to
different regulatory interpretations. ``Renewal'' typically implies a
process whereby the term of an existing license or CoC is extended. As
such, a renewal reaffirms the original design basis, perhaps with some
modifications. ``Reapproval,'' on the other hand, implies a process to
reevaluate the original design basis in accordance with current review
standards, which may be different from the standards in place when the
cask design was initially certified.
In addition, the Statements of Consideration (SOC) for the final
rule (55 FR 29184; July 18, 1990) that added the general license
provisions to part 72 stated that ``the procedure for reapproval of
cask designs was not intended to repeat all the analyses required for
the original approval.'' The referenced SOC also reported that, ``the
Commission believes that the staff should review spent fuel storage
cask designs periodically to consider any new information, either
generic to spent fuel storage or specific cask designs, that may have
arisen since issuance of the Certificate of Compliance.'' Clearly,
measures would need to be taken if the ``new information'' involves
safety concerns. These measures would depend on the nature of the
safety concerns and the cask design. Requests for Additional
Information (RAIs) may be generated during the renewal process to
prompt applicants for CoC renewals to address such safety concerns.
The NRC recognizes that a cask design certified years ago may not
meet the latest standards, yet that design may be fully acceptable to
continue to store spent fuel already loaded into casks of that design.
If the cask design were subject to a reapproval process, and as such,
to current standards, there is the possibility that certain components
of the original design would not meet the current standards. Under this
scenario, general licensees would be forced to remove the cask from
service and repackage the spent fuel. Obviously, there are significant
safety considerations if spent fuel were to be repackaged. When
considering repackaging, safety considerations associated with the
repackaging operation should be weighed against any safety concerns
with leaving the spent fuel in its existing storage container. Although
the NRC continuously updates its review standards, no compelling safety
concerns have been identified to date that warrant the removal of spent
fuel from a cask design that does not meet the latest review standards.
Thus, the NRC concludes that the review of extending the term of a
currently approved cask design is more in the nature of a renewal,
because it is based on the cask design standards in effect at the time
the CoC was approved, rather than a reapproval, which is based on the
current standards. By replacing the word ``reapproval'' with the word
``renewal,'' the final rule revisions will remove ambiguity from the
process for extending the terms of CoCs.

F. Why is the NRC adding a definition for the term ``time-limited aging
analyses'' (TLAAs)?

Stakeholders asked for a definition of TLAAs when they reviewed the
initial guidance document for the Surry and H. B. Robinson specific
ISFSI license renewals. TLAA is a process to assess systems,
structures, and components (SSCs) important to safety which have a
time-dependent operating life. This final rule adds a definition of
TLAA to the part 72 definitions section, Sec. 72.3, and makes
revisions to Sec. Sec. 72.42(a)(1) and 72.240(c)(2), respectively,
because TLAAs will be required for the renewal of a specific license
and for the renewal of a spent fuel storage cask CoC.

G. What is an ``aging management program'' (AMP)?

An AMP is a program for addressing aging effects that may include
prevention, mitigation, condition monitoring, and performance
monitoring. The final rule adds a definition of AMP to the part 72
definitions section, Sec. 72.3, because SSCs must be evaluated to
demonstrate that aging effects will not compromise the SSCs' intended
functions during the renewal period.

H. Why is the NRC requiring an AMP?

The NRC is amending Sec. Sec. 72.42 and 72.240 to require that
applicants for specific license and CoC renewals describe a program, in
their applications, for the management of issues associated with aging
that could adversely affect SSCs. In this regard, degradation of the
SSCs at an ISFSI, such as degradation due to corrosion and radiation,
are time-dependent mechanisms and are expected to be addressed in
renewal applications. AMP requirements will ensure that SSCs will
perform as designers intended during the renewal period. AMP
requirements will be reflected in the terms, conditions and technical
specifications of the renewed CoC and thus made applicable to the
general licensee per Sec. 72.212(b). For specific licensees, AMP
requirements will be reflected in the terms and conditions of the
renewed specific license.

I. Why is the NRC changing the 20-year general license term for cask
designs approved for use under the general license provisions? When
would a general license term begin and end?

The final rule changes the 20-year general license term limit for
the storage of spent fuel in casks fabricated under a CoC to be
consistent with the revisions to CoC initial and renewal terms (which

[[Page 8876]]

establish a CoC term not to exceed 40 years).
Under Sec. 72.210, a general license for the storage of spent fuel
in an ISFSI at power reactor sites is issued to those persons
authorized to possess or operate nuclear power reactors under 10 CFR
parts 50 or 52. The general license is limited to that spent fuel which
the general licensee is authorized to possess at the site under the
part 50 or 52 license for the site. The general license is further
limited to storage of spent fuel in casks approved and fabricated under
the provisions of subpart L of part 72; the approved cask designs are
listed in Sec. 72.214. Currently, the general licensee's authority to
use a particular cask design under an approved CoC terminates 20 years
after the date that the general licensee first uses the particular cask
to store spent fuel, unless the cask's CoC is renewed, in which case
the general license terminates 20 years after the CoC renewal date. In
the event the cask's CoC were to expire, any loaded spent fuel storage
casks of that design will need to be removed from service after a
storage period not to exceed 20 years.
This final rule amends Sec. Sec. 72.3 and 72.212(a)(3) to clarify
the term of the general license and to match the term of the general
license to the term of the applicable CoC. The final rule also amends
Sec. 72.3 by adding a definition for the phrase ``the term certified
by the cask's Certificate of Compliance,'' which is defined to mean,
for a CoC that is not renewed, the period of time commencing with the
CoC effective date and ending with the CoC expiration date, and for a
renewed CoC, the period of time commencing with the most recent CoC
renewal date and ending with the CoC expiration date.
The final rule amends Sec. 72.212(a)(3) to clarify that the term
of the general license runs through any renewal periods, unless
otherwise specified in the CoC. In addition, the final rule also amends
Sec. 72.212(a)(3) to clarify that the general license term for those
casks placed into service during the final renewal term of a CoC (i.e.,
during the CoC term immediately preceding the expiration of the CoC),
or similarly, during the term of a CoC that is not renewed, begins when
the cask is first used (i.e., when the cask is loaded with spent fuel)
and expires after a storage period not to exceed the length of ``the
term certified by the cask's Certificate of Compliance.''
The following scenarios are provided as illustrative examples:
Scenario 1: The CoC has a term of 20 years. The general licensee
places a cask into service at the end of the 19th year of the CoC term.
The CoC is not renewed and expires at the end of the 20th year; that is
1 year after the general licensee loaded the cask. The term of a
general license for a cask shall be for a storage period not to exceed
the term certified by the cask's CoC (i.e., for a CoC that is not
renewed, the period of time commencing with the CoC effective date and
ending with the CoC expiration date). Thus, in this scenario, the
general license commences upon loading at the end of the 19th year and
runs for 20 years (terminating 19 years after the date of the CoC
expiration, giving a storage period of 20 years).
Scenario 2: The initial CoC has a term of 20 years. The CoC is
renewed (by rulemaking amending the appropriate entry in Sec. 72.214)
for 40 years. The general licensee places a cask into service at the
end of the 39th year of the renewal term. The CoC is not renewed a
second time and as such, expires 40 years after the effective date of
the renewal amendment to Sec. 72.214 (here, 1 year after the general
licensee loaded the cask). The term of a general license for a cask
shall be for a storage period not to exceed the term certified by the
cask's CoC (i.e., for a renewed CoC, that is the period of time
commencing with the most recent CoC renewal date and ending with the
CoC expiration date). Thus, in this scenario, the term of the general
license for the cask would commence upon loading and terminate 40 years
after loading (in this case, 39 years after expiration of the CoC,
giving a storage period of 40 years).
Scenario 3: The initial CoC has a term of 20 years. The CoC is then
renewed for 40 years. The general licensee places a cask into service
at the end of the 39th year of the renewal term. The CoC is then
renewed a second time for an additional 40 years. In this case, the
general license would run through the second renewal period. Thus, the
general license for that cask would commence upon loading and terminate
at the expiration of the CoC (giving a storage period of 41 years).
Scenario 4: The initial CoC has a term of 20 years. The CoC is then
renewed for 40 years. The general licensee places a cask into service
at the end of the 39th year of the renewal term. The CoC is then
renewed two more times, each additional CoC renewal term being for a
40-year period. In this case, the general license would run through
both renewal periods. Thus, the general license for that cask would
commence upon loading and terminate at the expiration of the CoC
(giving a storage period of 81 years).
Scenario 5: The initial CoC has a term of 20 years. The CoC is then
renewed for 40 years. The CoC is then renewed a second and final time,
but only for a 30 year period. The general licensee places a cask into
service at the end of the 29th year of the final renewal term. In this
scenario, the general license for that cask would be for a storage
period not to exceed the term certified by the cask's CoC (for a
renewed CoC, that is the period of time commencing with the most recent
CoC renewal date and ending with the CoC expiration date). Thus, in
this scenario, the general license for this cask would commence upon
loading and terminate 30 years after loading (in this case, 29 years
after expiration of the CoC, giving a storage period of 30 years).
In short, the general license term for any given cask will be, at a
minimum, for a storage period not to exceed ``the term certified by the
cask's CoC'' (as that term is defined in Sec. 72.3). The rationale for
extending the general license through any CoC renewal term is two-fold.
First, the extension of the general license through a CoC renewal term
is premised upon the licensee implementing all appropriate aging
management requirements. Second, the NRC concluded that the
occupational risks of taking a cask out of service and repackaging the
spent fuel into another storage cask exceed the risks of leaving the
spent fuel in the original cask.

J. Are there possible conflicts that could arise for storage cask
designs that are granted a term extension that are also approved for a
different term limit as a transportation package?

The Commission raised this issue in its SRM for SECY-06-0152, dated
August 14, 2006. The NRC staff does not foresee any possible conflicts.
The current regulations in part 72 encourage, but do not require,
storage cask designs to have a compatible, approved transportation
cask. So called ``dual use'' systems must be separately certified under
the requirements in 10 CFR part 71 (transportation) and part 72
(storage). Typically, the only common item between these systems is the
inner canister, which holds the spent fuel contents.
Part 71 certificates for transportation packages are issued for a
5-year term whereas part 72 CoCs are issued for much longer periods
(under the current regulations, all approved CoCs have 20-year terms;
under this final rule, the CoC term is extended to a not to exceed 40-
year term). For each transportation cask certified under 10 CFR part
71, the CoC specifies ``approved contents.'' The description of the
approved contents for a spent fuel transportation package defines the
acceptable fuel types and

[[Page 8877]]

characteristics and, typically, it is the condition of the fuel, not
its age, that determines its acceptability. Spent fuel stored in casks,
even for extended terms, is not expected to experience any significant
degradation that would affect its acceptability to be shipped in a
suitable transportation cask. The part 72 general design criteria
require fuel retrievability (Sec. 72.122(l)) and for CoC applications,
the design of the storage cask should consider, to the extent
practicable, compatibility with removal of the stored spent fuel from a
reactor site, transportation, and ultimate disposition by the
Department of Energy (Sec. 72.236(m)). Based upon the NRC-supported
INL research program and the Surry and H. B. Robinson ISFSI renewal
applications, the NRC staff has concluded that typical spent fuel can
be safely stored in casks without appreciable degradation.
If the condition of spent fuel, or its storage canister, was
believed to have degraded during extended storage such that it no
longer met the criteria for approved contents, a licensee would have
other alternatives for transport of that spent fuel. A new or modified
approved transportation cask might be used, or the fuel might be
repackaged, to place it in an acceptable configuration.

K. How does the NRC track cask expiration dates?

Section 72.212(b)(2) of the final rule will require general
licensees to register use of each cask with the Commission no later
than 30 days after using that cask to store spent fuel. To register
casks, licensees must submit their name and address, reactor license
and docket numbers, the name and title of a person responsible for
providing additional information concerning spent fuel storage under
the general license, the cask certificate number, the amendment number,
if applicable, cask model number, and the cask identification number.
With this information, the Commission will know the loading and
expiration dates of each cask. This information will also enable the
NRC to schedule any necessary inspections and will permit the NRC to
maintain an independent record of use for each cask.

L. Who is responsible for applying for CoC renewals?

The final rule retains the structure of the current rule, which
emphasizes that the certificate holder (the cask vendor) applies for
cask renewal. If the certificate holder chooses not to apply for the
renewal of a particular cask design or is no longer in business, a
licensee, a licensee's representative, or another certificate holder
may apply for renewal in its place. If the applicant for CoC renewal
seeks to fabricate this cask design, it must satisfy the applicable
requirements of part 72, including establishment and maintenance of the
requisite quality assurance (QA) program (general licensees may rely
upon previously established part 50 or 71 QA programs if they meet the
requirements of Sec. Sec. 72.140 and 72.174).

M. Does the NRC have a definition for ``terms, conditions, and
specifications'' as they relate to the CoC?

The NRC does not include a definition for ``terms, conditions, and
specifications'' in the final rule because these words are generic in
nature, and are used in other parts of the NRC's regulations without
definition.

N. Can a licensee apply CoC amendments to previously loaded casks?

This final rule amends Sec. 72.212(b) to clarify that general
licensees may apply changes authorized by a CoC amendment to a
previously loaded cask provided that the licensee demonstrates, through
a written evaluation, that the cask meets the terms and conditions of
the subject CoC amendment (i.e., the loaded cask must conform to the
CoC amendment codified by the NRC in Sec. 72.214).

O. May a general licensee implement only some of the authorized changes
in a CoC amendment without prior NRC approval?

If a general licensee elects to apply the changes authorized by a
CoC amendment to a previously loaded cask, then the cask, after the
changes have been applied, must conform to the terms and conditions
(including the technical specifications) of the CoC amendment. Partial
or selective application of some of the authorized changes, but not
others, requires prior NRC approval (in this case, the general licensee
would apply for an exemption). The basis for allowing licensees to
apply the changes authorized by a CoC amendment to a previously loaded
cask without prior approval from the NRC is that the cask will remain
in an analyzed condition if, after the changes have been applied, it
conforms to the terms and conditions of the CoC amendment. The NRC has
previously stated, ``a spent fuel storage cask will be relied on to
provide safe confinement of radioactive material independent of a
nuclear power reactor's site, so long as conditions of the Certificate
of Compliance are met'' (54 FR 19381; May 5, 1989). However, partial or
selective application of a CoC amendment's changes could result in a
cask that would be in an unanalyzed condition.
In a related issue, the NRC agrees with an industry comment raised
in response to the publication of the draft preliminary rule text (73
FR 45173; August 4, 2008). The draft preliminary rule text required
that a general licensee ensure that once the changes authorized by a
CoC amendment had been applied to a previously loaded cask, that the
cask then ``fully conforms'' to the terms and conditions of the CoC
amendment. The industry comment raised the concern that the phrase
``fully conforms'' was overly restrictive and requiring conformance
with all the changes authorized by a CoC amendment would not be
feasible or logical in certain instances, namely, in those cases where
the amended CoC requirements do not apply to that particular general
licensee site or ISFSI (e.g., requirements for pressurized water
reactors (PWR) fuel at a boiling water reactor (BWR) plant).
In light of this comment, the final rule language now requires that
the cask, once CoC amendment changes have been applied, ``conforms'' to
the terms and conditions of the CoC amendment. Thus, CoC amendment
requirements for PWR fuel need not be met at a BWR plant.
Similarly, if the CoC amendment includes changes to the Technical
Specifications for loading, general licensees may have difficulty
demonstrating that the previously loaded cask complies with the new
loading requirements. As revised by this final rule, Sec. 72.212(b)(5)
will require general licensees to perform written evaluations prior to
applying the changes authorized by an amended CoC to a previously
loaded cask. If the evaluation indicates that the loading conditions
under the initial or older CoC amendment would not affect the ability
of the previously loaded cask to meet the storage or unloading
requirements of the newer CoC amendment, then the cask would be
considered as conforming with the terms and conditions of the newer CoC
amendment without having to meet the new loading requirements.

P. Do later CoC amendments encompass earlier CoC amendments?

No, later CoC amendments do not encompass earlier amendments unless
the language of the later CoC amendment expressly indicates otherwise.
Generally, when the NRC reviews an amendment to a CoC, the NRC staff
considers the changes associated with the amendment request only and
limits its review to the

[[Page 8878]]

bounding conditions of the analysis. Specific changes associated with
earlier CoC amendments for previously loaded casks are not considered
during the review process for a later amendment. Thus, depending on the
nature of the changes, later amendments do not necessarily encompass
earlier amendments and sometimes may be inconsistent with earlier
amendments.

Q. Why can't general licensees use the Sec. 72.48 process to apply CoC
amendment changes to previously loaded casks?

The principal requirement of Sec. 72.48 regarding changes to cask
designs is that the desired changes do not result in a change in the
terms, conditions, or specifications incorporated in the CoC. A
previously loaded cask is bound by the terms, conditions, and technical
specifications of the CoC applicable to that cask at the time the
licensee loaded the cask. Thus, under Sec. 72.48, a licensee may only
make those cask design changes that do not result in a change to the
terms, conditions, or specifications of the CoC under which the cask
was loaded. The final rule will not amend Sec. 72.48, but will amend
Sec. 72.212 by authorizing a general licensee to apply the changes
authorized by a CoC amendment to a previously loaded cask, provided
that after the changes have been applied, the cask conforms to the
terms and conditions, including the technical specifications, of the
CoC amendment.

R. If a general licensee selects and purchases a cask fabricated under
an earlier CoC amendment, but does not load the cask, can the general
licensee adopt the most recent CoC amendment for the empty cask before
loading it?

Adoption of the most recent CoC amendment depends on the nature of
the changes between the CoC amendment under which the cask system was
fabricated and the most recent amendment. CoC amendments are routinely
requested by cask manufacturers or vendors (also referred to as the
certificate holders) to account for advances in cask design and
technology. Some amendments will be associated with cask hardware
changes. A cask system that was purchased under an older amendment may
or may not be able to be modified to a cask system that meets the most
recent amendment.
As revised by this final rule, Sec. 72.212(b)(5) will require that
general licensees perform written evaluations demonstrating that the
cask, once loaded with spent fuel, will conform to the terms,
conditions and specifications of a CoC or an amended CoC listed in
Sec. 72.214. In the case of an unloaded cask fabricated under the
initial or earlier CoC amendment, the cask cannot be loaded under a
later CoC amendment if the Sec. 72.212(b)(5) evaluation shows that the
cask, once loaded, will fail to meet the terms, conditions and
specifications of the later CoC amendment. If the evaluation
demonstrates that the terms, conditions and specifications of the later
CoC amendment are met, then the cask can be loaded under the later CoC
amendment.

S. What are the NRC's plans for providing guidance and examples of
aging analyses and AMPs to licensees?

The NRC has developed NUREG-1927 ``Standard Review Plan for Renewal
of Independent Spent Fuel Storage Installation Licenses and Dry Cask
Storage System Certificates of Compliance.'' This SRP provides guidance
to the NRC staff in reviewing licensees' programs for managing the
effects of aging on spent fuel storage casks or ISFSI sites. Aging
analyses and AMPs are two components of an overall program for managing
the effects of aging. Because applicants will need to submit a TLAA and
a description of their program to manage the effects of aging when
applying for renewal of either CoCs or specific licenses under the
final rule, this SRP will also assist potential applicants in
identifying parameters to be included in a renewal application and
measures necessary to ensure that the cask or ISFSI can be operated
during the renewal period without undue risk to the public health and
safety. The SRP will be published following the publication of this
final rule.

T. Could the NRC maintain the current paragraph designations of Sec.
72.212(b)?

The NRC understands the burden arising from changing the paragraph
designations of a regulation. However, the NRC is rearranging the
provisions of Sec. 72.212(b) to better organize regulatory
requirements. For example, the final rule will group recordkeeping
requirements at the end of Sec. 72.212(b) rather than dispersing them
among other requirements, as is currently the case. The NRC's intent
for rearranging Sec. 72.212(b) is to make this provision more user-
friendly. These changes are documented in Table 1 located in Section IV
(Item 4) of this document (Discussion of Final Amendments by Section
under the discussion pertaining to Sec. 72.212).

U. When are licensees required to submit cask registration letters?

Under final Sec. 72.212(b)(2), general licensees must submit a
cask registration letter no later than 30 days after using that cask to
store spent fuel. One registration letter may be submitted for a
campaign that loads more than one cask, provided that the letter lists
the cask certificate number, the amendment number, the cask model
number, and the cask identification number of each cask covered by the
campaign.
In addition, under final Sec. 72.212(b)(4), general licensees must
submit a cask registration letter no later than 30 days after applying
the changes authorized by an amended CoC to a previously loaded cask.
One registration letter may be submitted for a campaign that applies
CoC amendment changes to more than one cask, provided that the letter
lists the cask certificate number, the amendment number to which the
cask will conform, the cask model number, and the cask identification
number of each cask covered by the campaign.

V. If a CoC is not renewed, how long would general licensees have to
remove casks of that design from service?

For those cask storage systems for which renewals are not planned,
general licensees should plan ahead to remove these cask storage
systems from service at or before the termination of the general
license (see the response to Question ``I'' above). Because users are
most aware of the general cask schedule and the number of casks to be
removed from service at their sites, users are in the best position to
develop a reasonable schedule for the removal.

W. When the NRC renews a CoC, are all amendments to that CoC
simultaneously renewed as well?

Section 72.214 lists one expiration date for each CoC. Amendments
under a CoC may have different effective dates; however, they share the
same certificate number and docket number. Therefore, when the NRC
renews a CoC, all amendments to that CoC are renewed as well.

X. If a general licensee applies for the renewal of a given CoC
(assuming the certificate holder went out of business or chose not to
apply for the renewal of a given CoC), and if the NRC approves the
renewal of that CoC, is the renewed CoC available only to that general
licensee or is it available to all general licensees?

CoCs are generic designs and approved by rulemaking. The renewed
CoC will be available to all persons who hold a general license under
Sec. 72.210.

[[Page 8879]]

Y. Can the requirements regarding TLAAs for CoC renewals be based upon
a ``current licensing basis'' (CLB) patterned after 10 CFR part 54?

The NRC does not believe that the part 54 CLB is the appropriate
basis for TLAAs in support of CoC renewals. The NRC does not believe
that it is appropriate for the CLB to be applied to cask CoC renewals,
which are generic. The CLB is typically the set of NRC requirements
applicable to a specific plant and a specific licensee's written
commitments for ensuring compliance with and operation within
applicable NRC requirements, including the plant specific design basis
(including all modifications and additions to regulatory commitments
over the life of the license) that are docketed and in effect.

Z. What is the status of the draft NRC Regulatory Issue Summary (RIS)
2007-26 which was issued on January 14, 2008 (73 FR 2281)?

The NRC decided not to finalize the draft RIS 2007-26 because Sec.
72.212(b) provides a path forward for implementation of later CoC
amendments to previously loaded casks. An Enforcement Guidance
Memorandum (EGM), dated September 15, 2009, was issued in conjunction
with the publication of the proposed rule to provide guidance to NRC
inspectors for exercising enforcement discretion concerning
deficiencies related to implementing changes, authorized by CoC
amendments to previously loaded casks, that occurred prior to issuance
of the EGM.

III. Summary and Analysis of Public Comments on the Proposed Rule

This section presents a summary of the public comments received on
the proposed rule and supporting documents, the NRC's response to the
comments, and changes made in the final rule and supporting documents
as a result of these comments.
The NRC received five comment letters on the proposed rule. These
comments came from the Nuclear Energy Institute, the U.S. Department of
Energy, Exelon Nuclear, Decommissioning Plant Coalition, and the
Prairie Island Indian Community. Three of the commenters supported the
new regulation, while two of the commenters expressed concern about the
proposed regulation. The commenters opposed to the proposed regulation
were primarily concerned about the increased license term extension
from 20 to 40 years for specific ISFSI licensees. One of these
commenters also had questions about the environmental review process.
The other commenters provided comments on different topics within the
proposed rule, including the proposed CoC terms, the CoC renewal
process, the CoC amendment process, TLAAs, and spent fuel storage in
general. These commenters made observations about these topics and
recommended areas within the proposed rule where the NRC could make
improvements. Two commenters suggested revisions to the proposed rule
language and the SOC.
Copies of the public comments are available for review in the NRC
Public Document Room, 11555 Rockville Pike, Rockville, MD 20852-2738. A
review of the comments and the NRC responses follow:

General Support

Comment 1
A commenter agreed with the proposed amendments and stated that
they are in the public interest and are consistent with scientific
evidence. The commenter also noted that the proposed regulation would
reduce the costs incurred by licensees and the NRC as a result of
preparing and reviewing applications and exemption requests. The
commenter stated that the proposed rule would provide the NRC and
regulated entities with greater regulatory certainty.
Response
The NRC agrees with the comment.

General Opposition

Comment 2
A commenter suggested that the proposed revisions would negatively
and directly impact their community and expressed opposition to
extending specific ISFSI licenses by 40 years. The commenter also
indicated that the proposed rule, along with the ``scrapping'' of Yucca
Mountain, would lead to permanent spent fuel storage at nuclear power
reactor sites. In addition, the commenter urged that the 20-year
initial and renewal terms should remain unchanged. The commenter
suggested that a 20-year term better protects the public because the
casks are monitored more frequently.
Response
The NRC acknowledges the concerns raised by the commenter. The
Commission believes there is reasonable assurance that spent fuel can
be stored safely and without significant environmental impacts at
ISFSIs during the extended license terms authorized by the final rule.
This reasonable assurance is partly based on the technical data gained
from an NRC supported research program and field data. Details are
discussed in the response to Question ``C'' of the ``Discussion''
section of this document. Furthermore, this final rule would require
all licensees to identify time-dependent degradations of the ISFSI SSCs
when they apply for license renewal. If any aging issues which could
adversely affect SSCs are identified, the final rule requires the
license renewal applicant to describe an AMP in its license renewal
application. The AMP will address the prevention and mitigation of
aging effects. The NRC staff will evaluate the AMP and will only
approve the renewal application if the AMP is deemed adequate.
An AMP would require licensees to monitor the casks and take other
measures to ensure public health and safety. AMP requirements will be
reflected in the terms and conditions of the renewed specific license,
which are enforceable by NRC. The NRC will monitor the licensee's
compliance with the terms and conditions of the license through the
NRC's inspection program. The NRC concluded that, with appropriate
aging management and maintenance programs, a license term up to 40
years is reasonable and provides adequate protection of public health
and safety.
Comment 3
A commenter stated that the proposed rule, ``like the proposed
revision of the Waste Confidence Rule,'' validated the commenter's
earlier concerns raised during the initial licensing process for the
ISFSI located near its Tribal boundary and ``exposes the false
assurances that the ISFSI is an interim or temporary solution.'' The
commenter added that the Commission's position is to ``simply
streamline approvals for extending the term that spent fuel can be
stored at either onsite or offsite ISFSIs.'' The commenter suggested
that ``regulatory requirements should be further enhanced rather than
relaxed.''
Response
The NRC has not made any regulatory or policy decision which states
that the storage of spent fuel at ISFSIs obviates the need for a
permanent repository of spent fuel and other high-level waste. The
establishment of such a repository is a national policy decision and is
beyond the scope of this rulemaking.
The extension of specific license terms in Sec. 72.42 does not
relax any regulatory requirements. The rationale for extending the
terms for specific ISFSI licenses, for both initial terms and

[[Page 8880]]

renewals, is set forth in the responses to Questions ``C'', ``D'', and
``F-H'', in Section II of this document. The rule requires that any
applicant for license renewal demonstrate the safety of the continued
storage of spent fuel for the requested term through TLAAs and the
establishment of an AMP. If the applicant demonstrates to the NRC
appropriate aging management and maintenance programs, then the NRC has
concluded that a renewal term up to 40 years is reasonable and provides
adequate protection of public health and safety.

CoC Terms and Renewal Process

Comment 4
A commenter stated that the term ``unloaded cask'' in the fifth
paragraph of Section II, ``Discussion,'' Question ``E'', of the
proposed rule is unclear. The commenter asked whether the term
``unloaded cask'' is limited to a cask that has never been loaded or if
it also includes a cask that has been used but subsequently unloaded of
stored fuel. The commenter added that the review of a generic CoC
renewal should not depend on whether or not a particular cask is
unloaded. The commenter requested that the NRC delete the final
sentence of the fifth paragraph of Section II, ``Discussion,'' Question
``E.''
Response
In the context of the response to Question ``E'', the NRC
considered the term ``unloaded cask'' to be either a cask that has
never been loaded or one that was loaded and then subsequently
unloaded. In any event, the NRC agrees with the comment. When a CoC is
renewed by the NRC, it is the cask design that is being renewed. It
does not matter whether the cask is loaded or not. Therefore,
clarifying changes have been made to the response to Question ``E'',
including the deletion of the sentence which contains the term
``unloaded cask.''
Comment 5
Two commenters requested that NRC clarify Section II,
``Discussion,'' Questions ``I'' and ``V'' and Section III, ``Discussion
of Proposed Amendments by Section,'' Item 4 and Sec. 72.212(a)(3) of
the proposed rule. These sections of the SOC and Sec. 72.212(a)(3)
address the relationship between the term of a general license, the CoC
term and renewal, and the date an individual cask is loaded.
One of the commenters stated that ``[i]ndustry believes that each
individual cask should be permitted to be operated for the full design
life of the cask, including the full renewal period.'' The commenter
stated that aging management requirements would be implemented during
the renewal period. This commenter then provided two examples: the
first, ``a cask loaded under an active CoC with a 20-year initial term
and not renewed should be permitted to be operated under a general
license for 20 years from the date of initial use, no matter when that
cask is placed into service;'' and the second, ``a cask loaded under an
active CoC with a 20-year initial term and renewed for 40 years should
be permitted to be operated under a general license for 60 years from
the date of initial use, no matter when that cask is placed into
service.''
The commenter then asserted that each cask is fabricated to meet a
specific design life and that the ``successful renewal of the CoC
extends that design life provided all design and maintenance parameters
that were part of the renewal approval are met.'' The commenter further
asserts that the design life ``does not begin for each individual cask
until the cask is loaded, i.e., the cask is experiencing the conditions
contemplated in design.'' The commenter concluded that ``forcing casks
to be taken out of service at an arbitrary date would result in
unnecessary fuel repackaging and occupational radiation exposition with
no commensurate public health and safety benefit.''
The second commenter made a similar comment, stating that the
``cask life should be solely based on the qualification of the cask,
and not on the CoC expiration date.'' The commenter then suggested that
``the NRC consider evaluating the lifespan of the fuel storage system
based on date of loading (i.e., activation of the system) of the cask
system in compliance with all applicable terms, conditions, and
specification, and not based on other external factors.''
Response
The NRC agrees, in part, and disagrees, in part, with the comments.
The part 72 regulations do not define the term ``design life.'' Rather,
the part 72 regulatory scheme is based on licenses, specific and
general, and the terms of those licenses. The general license term is
premised upon the CoC in effect at the time the cask was placed into
service (i.e., loaded with spent fuel and deployed onto the ISFSI pad).
As explained in the response to Question ``I'' of Section II, the
general license term, for loaded casks, will run through any
consecutive CoC renewal terms as the occupational risk of unloading a
cask and repackaging the spent fuel into another storage cask exceeds
the risk of keeping the spent fuel in the original cask.
The NRC agrees with the first commenter's statement regarding the
implementation of aging management requirements during the renewal
period. The NRC further agrees with the first commenter's first example
regarding a cask fabricated under a 20-year CoC term, which is not
renewed. Under both the current regulation and the regulation as
revised by this final rule, the general license term for such a cask
would be 20 years, regardless of when during the 20-year CoC term the
cask is placed into service. Of course, after the CoC expires, casks of
that design could no longer be placed into service.
The NRC disagrees with the second example and the commenter's
rationale to support that example. The commenter states ``a cask loaded
under an active CoC with a 20-year initial term and renewed for 40
years should be permitted to be operated under a general license for 60
years from the date of initial use, no matter when that cask is placed
into service'' (emphasis added). The NRC does not agree that successful
renewals of the CoC cumulatively extend the general license term for
that cask (the commenter uses the term ``design life,'' which the NRC
assumes to be the equivalent of the general license term desired by the
commenter). The commenter uses the example of a CoC that has an initial
term of 20 years followed by a renewal term of 40 years. The commenter
then asserts that the design life of the cask would be 60 years. Thus,
under this reasoning, a cask placed into service the day before the
renewed CoC expires could be in service for 60 years. Essentially, the
commenter appears to be asserting that the regulatory scheme should
allow cumulative terms, such that each successive renewal of the CoC
adds to the design life of the cask, and thus, to the term of the
general license.
The intent of the amendments implemented by the final rule is that
the use of a cask is determined by the general license term, which in
turn is determined by the term specified in the applicable CoC in
effect at the time the cask is placed into service; the general license
term is not determined by adding all the successive CoC renewal terms
to the initial CoC term. The term of the general license for any cask
placed into service during a CoC renewal term is based upon the length
of the renewal term (renewal date to expiration). Thus, if a CoC is
renewed for 40 years and a cask fabricated under that CoC is placed
into service during the 39th year of the renewal term, the

[[Page 8881]]

general license for that cask would be 40 years.
According to the commenter, if the initial term of the CoC was 20
years, and the CoC was then renewed twice, each time for 40 years, then
a cask placed into service on the last day of the second renewal period
would have a general license of 100 years (essentially, 100 years
beyond the CoC expiration date). It is not the intent of the NRC to
allow for such extended, cumulative license terms.\1\ Such an
interpretation of the regulatory scheme implemented by this final rule
is well beyond the regulatory norm and is not aligned with the stated
purpose of this rulemaking, which was to extend specific license terms
from not to exceed 20 years to not to exceed 40 years and then to make
the terms of CoCs and general licenses equal with those of specific
licenses.
---------------------------------------------------------------------------

\1\ As background, see the response to Question 21 in the July
18, 1990 (55 FR 29186), final rule that promulgated subparts K and L
of part 72. In particular, the NRC stated that ``the 20-year storage
period will also apply to new casks put into use after a Certificate
of Compliance is reapproved.'' Clearly, there was no intent that the
storage period for a cask placed into service during the renewal
term was to be for a term that was equal to the initial term plus
the renewal term.
---------------------------------------------------------------------------

The NRC disagrees with the second commenter, who stated that ``cask
life should be solely based on the qualification of the cask, and not
on the CoC expiration date.'' In this regard, the NRC will allow for
casks already in service, i.e., those already loaded prior to any given
CoC renewal, to remain in service through any future renewal periods,
given that the occupational hazards associated with unloading a cask
and repackaging the spent fuel into another storage cask exceed the
risks of leaving that fuel in the original cask. However, this is not
the same as allowing an unloaded cask (i.e., either a new cask or one
formerly loaded and then subsequently unloaded) to be placed into
service for a cumulative term that is equal to the length of the
initial te
