Introduction The Nuclear Regulatory Commission (NRC or Commission) is considering issuance of a one-time exemption to Virginia Electric and Power Company (Dominion or licensee) pursuant to 10 CFR 72.7 from the requirements of 10 CFR 72.212(b)(3) and the portion of 72.212(b)(11) which requires compliance with the terms, conditions, and specifications of the CoC. Dominion submitted its exemption request by letter dated July 21, 2011, as supplemented September 28, 2011. Dominion has loaded spent nuclear fuel into Transnuclear, Inc. (TN) NUHOMS® HD Storage System (HD–32PTH) dry storage casks, under the Certificate of Compliance (CoC or Certificate) No. 1030, Amendment No. 0. The licensee inadvertently reversed the upper and lower zones while preparing the dry shielded canister (DSC) loading maps. This resulted in five fuel assemblies being loaded into four DSCs with decay heat greater than the levels specified in the CoC. Dominion requests a one-time exemption to the 10 CFR Part 72 requirements to continue storage of the affected DSCs with serial numbers DOM–32PTH–001–C, –002–C, –003–C, and –009–C in their current condition at the Independent Spent Fuel Storage Installation (ISFSI) associated with the operation of Dominion’s nuclear power reactors, Surry Power Station Units 1 and 2, located in Surry County, Virginia. II. Environmental Assessment (EA) Identification of Proposed Action: The CoC is the NRC approved design for each dry storage cask system. The proposed action would grant Dominion a one-time exemption from the requirements of 10 CFR 72.212(b)(3) and from the portion of 72.212(b)(11) that states the licensee shall comply with the terms, conditions, and specifications of the CoC, to the extent necessary to enable Dominion to continue storage of the four DSCs in their current condition at the ISFSI associated with Surry Power Station Units 1 and 2. These regulations specifically require storage of spent nuclear fuel under a general license in dry storage casks approved under the provisions of 10 CFR part 72, and compliance with the terms and conditions set forth in the CoC for each dry spent fuel storage cask used by an ISFSI general licensee. The TN NUHOMS® HD dry cask storage system CoC provides requirements, conditions and operating limits in Attachment A, Technical Specifications (TS). The TS restrict the decay heat in lower Zone ‘‘1a’’ locations PO 00000 Frm 00088 Fmt 4703 Sfmt 4703 to ≤ 1.05 kW and the upper Zone ‘‘1b’’ locations to ≤ 0.8 kW. The applicant inadvertently reversed the upper and lower zones while preparing the DSC loading maps. This resulted in five fuel assemblies being loaded into four DSCs (serial numbers DOM–32PTH–001–C, –002–C, –003–C, and –009–C) with decay heat greater than specified in the CoC. The maximum decay heat of the misloaded fuel assemblies at the time of loading was 0.806 kW, which exceeded the Zone ‘‘1b’’ limit mentioned above by six watts. Currently, the five affected fuel assemblies have been in storage for a minimum of 2.5 years and have decayed to meet the required decay heat limits of the CoC. The proposed action would grant Dominion a one-time exemption from the requirements of 10 CFR 72.212(b)(3) and the portion of 72.212(b)(11) which requires compliance with the terms, conditions, and specifications of a CoC, in order to allow continued storage of the four affected DSCs in their current condition. This exemption approval is only valid for DSCs with serial numbers DOM–32PTH–001–C, –002–C, –003–C, and –009–C, at the Surry Power Station ISFSI. Need for the Proposed Action: Dominion requested this exemption in order to continue storage of four asloaded DSCs containing five fuel assemblies which exceeded the CoC decay heat limits at the time of loading. Dominion, with the assistance of TN, has provided an evaluation and thermal analysis which shows that the affected DSCs remain bounded by the system’s design basis limits and that the continued storage of the fuel in the asloaded configuration is safe. Dominion has considered an alternative to the proposed action, which would correct the condition by reloading the affected DSCs to be in compliance with CoC No. 1030. This would involve retrieving each of the DSCs from their Horizontal Storage Modules (HSM), unloading the spent fuel assemblies from the DSC, performing inspections of various DSC components, reloading the spent fuel assemblies into the used DSC or a new DSC (if there was damage noted on the used DSC) in accordance with CoC No. 1030, performing the DSC closing procedures, and transferring the DSC back to the ISFSI for re-insertion into the HSM. Dominion estimates this alternative action of loading and unloading operations would increase personnel exposures by 250 mRem per affected DSC. In addition, Dominion states the alternative to the proposed action would generate radioactive contaminated E:\FR\FM\04APN1.SGM 04APN1 emcdonald on DSK29S0YB1PROD with NOTICES Federal Register / Vol. 77, No. 65 / Wednesday, April 4, 2012 / Notices material and waste during loading and unloading operations and disposal of the used DSCs if the DSCs were damaged during the unloading process. The licensee estimates the alternative to the proposed action would cost an estimated $300,000 for unloading and reloading operations of each affected DSC and also necessitate additional fuel handling operations. If the DSC was damaged during unloading, the licensee estimates an additional $1,000,000 for purchase of a new DSC and $200,000 for disposal of the used DSC. The proposed action is necessary to document the acceptability and safety basis for storage of the DSCs in the asloaded configuration, thus precluding the need to unload the four DSCs. Environmental Impacts of the Proposed Action: The NRC staff has determined that the proposed action would not endanger life or property. The potential impact of using the NUHOMS® HD dry cask storage system was initially presented in the Environmental Assessment (EA) for the rulemaking to add the TN NUHOMS® HD Horizontal Modular Storage System for Irradiated Nuclear Fuel to the list of approved spent fuel storage casks in 10 CFR 72.214 (71 FR 25740, dated May 2, 2006 (Direct Final Rule), and 71 FR 71463, dated December 11, 2006 (Final Rule)). The licensee submitted TN Calculation No. 10494–174, which performed bounding thermal analysis using ANSYS finite element software to evaluate the misloading events. The licensee concluded the maximum fuel cladding temperature for the as loaded DSCs remained below the fuel cladding temperature limit used in the Updated Safety Analysis Report dated October 2, 2009. The NRC staff performed an independent safety evaluation of the proposed exemption and determined that loading of the spent nuclear fuel with higher than allowable decay heat loads did not exceed the structural and shielding design basis and that the fuel cladding temperatures are below the temperature limit at the time of loading. The fuel assemblies have since decayed to meet the CoC limits. There are no changes being made in the types or amounts of any radiological effluents that may be released offsite, and there is no significant increase in occupational or public radiation exposure as a result of the proposed activities. Therefore, there are no significant radiological environmental impacts associated with the proposed action. The proposed action only affects the requirements associated with the fuel assemblies already loaded into the casks and does not affect non- VerDate Mar<15>2010 15:28 Apr 03, 2012 Jkt 226001 radiological plant effluents, or any other aspects of the environment. Therefore, there are no significant non-radiological impacts associated with the proposed action. Accordingly, the Commission concludes that there are no significant environmental impacts associated with the proposed action. Alternative to the Proposed Action: Because there is no significant environmental impact associated with the proposed action, alternatives with equal or greater environmental impact were not evaluated. As an alternative to the proposed action, the NRC staff considered denial of the proposed action which would involve reloading the affected DSCs as described previously. Denial of the exemption would result in an increase in radiological exposure to workers, a small potential for radioactive releases to the environment due to radioactive material handling, additional opportunities for accidents, and increased cost to the licensee. Therefore, the NRC staff has determined that approving the proposed action has a lesser environmental impact than denying the proposed action. Agencies and Persons Consulted: The environmental assessment associated with this exemption request was sent to Ms. Ellie Irons of the Virginia Department of Environmental Quality in the Office of Environmental Impact Review, by letter dated November 14, 2011 (ML113180499). The state response was received by letter dated December 14, 2011 (ML120030312). The letter states that the proposed action is unlikely to have significant effects on ambient air quality, historic resources, surface waters, and wetlands. The letter also states that it is unlikely to adversely affect species of plants or insects listed by state agencies as rare, threatened, or endangered. Furthermore, the Virginia Department of Health considered the alternative to the proposed action of reloading the casks presents several risks, namely additional radiation exposure to workers and potential accidents that may lead to dispersal of radiation to the environment. Thus, the Virginia Department of Health states that it supports the exemption without reservation. The NRC staff has determined that a consultation under Section 7 of the Endangered Species Act is not required because the proposed action will not affect listed species or a critical habitat. The NRC staff has also determined that the proposed action is not a type of activity having the potential to cause effects on historic properties. Therefore, no consultation is PO 00000 Frm 00089 Fmt 4703 Sfmt 4703 20441 required under Section 106 of the National Historic Preservation Act. III. Finding of No Significant Impact The environmental impacts of the proposed action have been reviewed in accordance with the requirements set forth in 10 CFR part 51. Based upon the foregoing Environmental Assessment, the Commission finds that the proposed action of granting the one-time exemption from the requirements of 10 CFR 72.212(b)(3) and the portion of 72.212(b)(11) which requires compliance with the terms, conditions, and specifications of the CoC in order to allow Dominion to store spent fuel assemblies in DSCs with serial numbers DOM–32PTH–001–C, –002–C, –003–C, and –009–C in the as-loaded configuration at the ISFSI associated with Surry Power Station Units 1 and 2, will not significantly impact the quality of the human environment. Accordingly, the Commission has determined that an environmental impact statement for the proposed exemption is not warranted and that a finding of no significant impact is appropriate. IV. Further Information In accordance with 10 CFR 2.390 of NRC’s ‘‘Rules of Practice,’’ final NRC records and documents regarding this proposed action are publicly available in the records component of NRC’s Agencywide Documents Access and Management System (ADAMS).

SUPPLEMENTARY INFORMATION: 

I. Introduction

    The Nuclear Regulatory Commission (NRC or Commission) is 
considering issuance of a one-time exemption to Virginia Electric and 
Power Company (Dominion or licensee) pursuant to 10 CFR 72.7 from the 
requirements of 10 CFR 72.212(b)(3) and the portion of 72.212(b)(11) 
which requires compliance with the terms, conditions, and 
specifications of the CoC. Dominion submitted its exemption request by 
letter dated July 21, 2011, as supplemented September 28, 2011. 
Dominion has loaded spent nuclear fuel into Transnuclear, Inc. (TN) 
NUHOMS[supreg] HD Storage System (HD-32PTH) dry storage casks, under 
the Certificate of Compliance (CoC or Certificate) No. 1030, Amendment 
No. 0. The licensee inadvertently reversed the upper and lower zones 
while preparing the dry shielded canister (DSC) loading maps. This 
resulted in five fuel assemblies being loaded into four DSCs with decay 
heat greater than the levels specified in the CoC. Dominion requests a 
one-time exemption to the 10 CFR Part 72 requirements to continue 
storage of the affected DSCs with serial numbers DOM-32PTH-001-C, -002-
C, -003-C, and -009-C in their current condition at the Independent 
Spent Fuel Storage Installation (ISFSI) associated with the operation 
of Dominion's nuclear power reactors, Surry Power Station Units 1 and 
2, located in Surry County, Virginia.

II. Environmental Assessment (EA)

    Identification of Proposed Action: The CoC is the NRC approved 
design for each dry storage cask system. The proposed action would 
grant Dominion a one-time exemption from the requirements of 10 CFR 
72.212(b)(3) and from the portion of 72.212(b)(11) that states the 
licensee shall comply with the terms, conditions, and specifications of 
the CoC, to the extent necessary to enable Dominion to continue storage 
of the four DSCs in their current condition at the ISFSI associated 
with Surry Power Station Units 1 and 2. These regulations specifically 
require storage of spent nuclear fuel under a general license in dry 
storage casks approved under the provisions of 10 CFR part 72, and 
compliance with the terms and conditions set forth in the CoC for each 
dry spent fuel storage cask used by an ISFSI general licensee.
    The TN NUHOMS[supreg] HD dry cask storage system CoC provides 
requirements, conditions and operating limits in Attachment A, 
Technical Specifications (TS). The TS restrict the decay heat in lower 
Zone ``1a'' locations to <= 1.05 kW and the upper Zone ``1b'' locations 
to <= 0.8 kW. The applicant inadvertently reversed the upper and lower 
zones while preparing the DSC loading maps. This resulted in five fuel 
assemblies being loaded into four DSCs (serial numbers DOM-32PTH-001-C, 
-002-C, -003-C, and -009-C) with decay heat greater than specified in 
the CoC. The maximum decay heat of the misloaded fuel assemblies at the 
time of loading was 0.806 kW, which exceeded the Zone ``1b'' limit 
mentioned above by six watts. Currently, the five affected fuel 
assemblies have been in storage for a minimum of 2.5 years and have 
decayed to meet the required decay heat limits of the CoC.
    The proposed action would grant Dominion a one-time exemption from 
the requirements of 10 CFR 72.212(b)(3) and the portion of 
72.212(b)(11) which requires compliance with the terms, conditions, and 
specifications of a CoC, in order to allow continued storage of the 
four affected DSCs in their current condition. This exemption approval 
is only valid for DSCs with serial numbers DOM-32PTH-001-C, -002-C, -
003-C, and -009-C, at the Surry Power Station ISFSI.
    Need for the Proposed Action: Dominion requested this exemption in 
order to continue storage of four as-loaded DSCs containing five fuel 
assemblies which exceeded the CoC decay heat limits at the time of 
loading. Dominion, with the assistance of TN, has provided an 
evaluation and thermal analysis which shows that the affected DSCs 
remain bounded by the system's design basis limits and that the 
continued storage of the fuel in the as-loaded configuration is safe.
    Dominion has considered an alternative to the proposed action, 
which would correct the condition by reloading the affected DSCs to be 
in compliance with CoC No. 1030. This would involve retrieving each of 
the DSCs from their Horizontal Storage Modules (HSM), unloading the 
spent fuel assemblies from the DSC, performing inspections of various 
DSC components, reloading the spent fuel assemblies into the used DSC 
or a new DSC (if there was damage noted on the used DSC) in accordance 
with CoC No. 1030, performing the DSC closing procedures, and 
transferring the DSC back to the ISFSI for re-insertion into the HSM.
    Dominion estimates this alternative action of loading and unloading 
operations would increase personnel exposures by 250 mRem per affected 
DSC. In addition, Dominion states the alternative to the proposed 
action would generate radioactive contaminated

[[Page 20441]]

material and waste during loading and unloading operations and disposal 
of the used DSCs if the DSCs were damaged during the unloading process. 
The licensee estimates the alternative to the proposed action would 
cost an estimated $300,000 for unloading and reloading operations of 
each affected DSC and also necessitate additional fuel handling 
operations. If the DSC was damaged during unloading, the licensee 
estimates an additional $1,000,000 for purchase of a new DSC and 
$200,000 for disposal of the used DSC.
    The proposed action is necessary to document the acceptability and 
safety basis for storage of the DSCs in the as-loaded configuration, 
thus precluding the need to unload the four DSCs.
    Environmental Impacts of the Proposed Action: The NRC staff has 
determined that the proposed action would not endanger life or 
property. The potential impact of using the NUHOMS[supreg] HD dry cask 
storage system was initially presented in the Environmental Assessment 
(EA) for the rulemaking to add the TN NUHOMS[supreg] HD Horizontal 
Modular Storage System for Irradiated Nuclear Fuel to the list of 
approved spent fuel storage casks in 10 CFR 72.214 (71 FR 25740, dated 
May 2, 2006 (Direct Final Rule), and 71 FR 71463, dated December 11, 
2006 (Final Rule)).
    The licensee submitted TN Calculation No. 10494-174, which 
performed bounding thermal analysis using ANSYS finite element software 
to evaluate the misloading events. The licensee concluded the maximum 
fuel cladding temperature for the as loaded DSCs remained below the 
fuel cladding temperature limit used in the Updated Safety Analysis 
Report dated October 2, 2009. The NRC staff performed an independent 
safety evaluation of the proposed exemption and determined that loading 
of the spent nuclear fuel with higher than allowable decay heat loads 
did not exceed the structural and shielding design basis and that the 
fuel cladding temperatures are below the temperature limit at the time 
of loading. The fuel assemblies have since decayed to meet the CoC 
limits. There are no changes being made in the types or amounts of any 
radiological effluents that may be released offsite, and there is no 
significant increase in occupational or public radiation exposure as a 
result of the proposed activities. Therefore, there are no significant 
radiological environmental impacts associated with the proposed action. 
The proposed action only affects the requirements associated with the 
fuel assemblies already loaded into the casks and does not affect non-
radiological plant effluents, or any other aspects of the environment. 
Therefore, there are no significant non-radiological impacts associated 
with the proposed action.
    Accordingly, the Commission concludes that there are no significant 
environmental impacts associated with the proposed action.
    Alternative to the Proposed Action: Because there is no significant 
environmental impact associated with the proposed action, alternatives 
with equal or greater environmental impact were not evaluated. As an 
alternative to the proposed action, the NRC staff considered denial of 
the proposed action which would involve reloading the affected DSCs as 
described previously. Denial of the exemption would result in an 
increase in radiological exposure to workers, a small potential for 
radioactive releases to the environment due to radioactive material 
handling, additional opportunities for accidents, and increased cost to 
the licensee. Therefore, the NRC staff has determined that approving 
the proposed action has a lesser environmental impact than denying the 
proposed action.
    Agencies and Persons Consulted: The environmental assessment 
associated with this exemption request was sent to Ms. Ellie Irons of 
the Virginia Department of Environmental Quality in the Office of 
Environmental Impact Review, by letter dated November 14, 2011 
(ML113180499). The state response was received by letter dated December 
14, 2011 (ML120030312). The letter states that the proposed action is 
unlikely to have significant effects on ambient air quality, historic 
resources, surface waters, and wetlands. The letter also states that it 
is unlikely to adversely affect species of plants or insects listed by 
state agencies as rare, threatened, or endangered. Furthermore, the 
Virginia Department of Health considered the alternative to the 
proposed action of reloading the casks presents several risks, namely 
additional radiation exposure to workers and potential accidents that 
may lead to dispersal of radiation to the environment. Thus, the 
Virginia Department of Health states that it supports the exemption 
without reservation. The NRC staff has determined that a consultation 
under Section 7 of the Endangered Species Act is not required because 
the proposed action will not affect listed species or a critical 
habitat. The NRC staff has also determined that the proposed action is 
not a type of activity having the potential to cause effects on 
historic properties. Therefore, no consultation is required under 
Section 106 of the National Historic Preservation Act.

III. Finding of No Significant Impact

    The environmental impacts of the proposed action have been reviewed 
in accordance with the requirements set forth in 10 CFR part 51. Based 
upon the foregoing Environmental Assessment, the Commission finds that 
the proposed action of granting the one-time exemption from the 
requirements of 10 CFR 72.212(b)(3) and the portion of 72.212(b)(11) 
which requires compliance with the terms, conditions, and 
specifications of the CoC in order to allow Dominion to store spent 
fuel assemblies in DSCs with serial numbers DOM-32PTH-001-C, -002-C, -
003-C, and -009-C in the as-loaded configuration at the ISFSI 
associated with Surry Power Station Units 1 and 2, will not 
significantly impact the quality of the human environment. Accordingly, 
the Commission has determined that an environmental impact statement 
for the proposed exemption is not warranted and that a finding of no 
significant impact is appropriate.

IV. Further Information

    In accordance with 10 CFR 2.390 of NRC's ``Rules of Practice,'' 
final NRC records and documents regarding this proposed action are 
publicly available in the records component of NRC's Agencywide
