[(aggregated source activity for radionuclide A) ÷ (quantity of concern for radionuclide A)] + [(aggregated source activity for radionuclide B) ÷ (quantity of concern for radionuclide B)] + etc. * * * ≥1. Guidance for Aggregation of Sources NRC supports the use of the International Atomic Energy Association’s (IAEA) source categorization methodology as defined in IAEA Safety Standards Series No. RS–G–1.9, ‘‘Categorization of Radioactive Sources,’’ (2005) (see https:// www-pub.iaea.org/MTCD/publications/ PDF/Pub1227_web.pdf) and as endorsed by the agency’s Code of Conduct for the Safety and Security of Radioactive Sources, January 2004 (see https://wwwpub.iaea.org/MTCD/publications/PDF/ Code-2004_web.pdf). The Code defines a three-tiered source categorization scheme. Category 1 corresponds to the largest source strength (equal to or greater than 100 times the quantity of concern values listed in Table 1.) and Category 3, the smallest (equal or exceeding one-tenth the quantity of concern values listed in Table 1.). Additional security measures apply to sources that are equal to or greater than the quantity of concern values listed in Table 1, plus aggregations of smaller sources that are equal to or greater than the quantities in Table 1. Aggregation only applies to sources that are collocated. Licensees who possess individual sources in total quantities that equal or exceed the Table 1 quantities are required to implement additional security measures. Where there are many small (less than the quantity of concern values) collocated sources whose total aggregate activity equals or exceeds the Table 1 values, licensees are to implement additional security measures. Some source handling or storage activities may cover several buildings, or several locations within specific buildings. The question then becomes, ‘‘When are sources considered collocated for purposes of aggregation?’’ For purposes of the additional controls, sources are considered collocated if breaching a single barrier (e.g., a locked door at the entrance to a storage room) would allow access to the sources. Sources behind an outer barrier should be aggregated separately from those behind an inner barrier (e.g., a locked source safe inside the locked storage room). However, if both barriers are simultaneously open, then all sources within these two barriers are considered to be collocated. This logic should be VerDate Aug<31>2005 16:53 Oct 26, 2006 Jkt 211001 continued for other barriers within or behind the inner barrier. The following example illustrates the point: A lockable room has sources stored in it. Inside the lockable room, there are two shielded safes with additional sources in them. Inventories are as follows: The room has the following sources outside the safes: Cf–252, 0.12 TBq (3.2 Ci); Co–60, 0.18 TBq (4.9 Ci), and Pu–238, 0.3 TBq (8.1 Ci). Application of the unity rule yields: (0.12 ÷ 0.2) + (0.18 ÷ 0.3) + (0.3 ÷ 0.6) = 0.6 + 0.6 + 0.5 = 1.7. Therefore, the sources would require additional security measures. Shielded safe #1 has a 1.9 TBq (51 Ci) Cs– 137 source and a 0.8 TBq (22 Ci) Am–241 source. In this case, the sources would require additional security measures, regardless of location, because they each exceed the quantities in Table 1. Shielded safe #2 has two Ir–192 sources, each having an activity of 0.3 TBq (8.1 Ci). In this case, the sources would not require additional security measures while locked in the safe. The combined activity does not exceed the threshold quantity 0.8 TBq (22 Ci). Because certain barriers may cease to exist during source handling operations (e.g., a storage location may be unlocked during periods of active source usage), licensees should, to the extent practicable, consider two modes of source usage—‘‘operations’’ (active source usage) and ‘‘shutdown’’ (source storage mode). Whichever mode results in the greatest inventory (considering barrier status) would require additional security measures for each location. Use the following method to determine which sources of radioactive material require implementation of the Additional Security Measures (ASMs): • Include any single source equal to or greater than the quantity of concern in Table A. • Include multiple collocated sources of the same radionuclide when the combined quantity equals or exceeds the quantity of concern. • For combinations of radionuclides, include multiple collocated sources of different radionuclides when the aggregate quantities satisfy the following unity rule: [(amount of radionuclide A) ÷ (quantity of concern of radionuclide A)] + [(amount of radionuclide B) ÷ (quantity of concern of radionuclide B)] + etc. . . . ≥1.

ACTION: Notice of availability. AGENCY: SUMMARY: Notice is hereby given that the staff of the Nuclear Regulatory Commission (NRC) has prepared a model safety evaluation (SE) relating to the modification of shutdown testing requirements in technical specifications (TS) for Boiling Water Reactors (BWR). The NRC staff has also prepared a model no-significant-hazards-consideration (NSHC) determination relating to this matter. The purpose of these models is to permit the NRC to efficiently process amendments that propose to modify LCO 3.10.1. The proposed changes would revise LCO 3.10.1, and the associated Bases, to expand its scope to include provisions for temperature excursions greater than [200] °F as a consequence of inservice leak and hydrostatic testing, and as a consequence of scram time testing initiated in conjunction with an inservice leak or hydrostatic test, while considering operational conditions to be in Mode 4. Licensees of nuclear power reactors to which the models apply could then request amendments, confirming the applicability of the SE and NSHC determination to their reactors. The NRC staff issued a Federal Register notice on August 21, 2006 (71 FR 48561) that provided a model safety evaluation (SE) and a model no significant hazards consideration (NSHC) determination relating to modification of requirements regarding LCO 3.10.1, ‘‘Inservice Leak and Hydrostatic Testing Operation.’’ The NRC staff hereby announces that the model SE and NSHC determination may be referenced in plant-specific applications to adopt the changes.

FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: jlentini on PROD1PC65 with NOTICES Regulatory Issue Summary 2000–06, ‘‘Consolidated Line Item Improvement Process for Adopting Standard Technical Specification Changes for Power Reactors,’’ was issued on March 20, 2000. The consolidated line item improvement process (CLIIP) is intended to improve the efficiency of NRC licensing processes by processing proposed changes to the standard technical specifications (STS) in a manner that supports subsequent license amendment applications. The CLIIP includes an opportunity for the public to comment on a proposed change to the STS after a preliminary assessment by the NRC staff and a finding that the change will likely be offered for adoption by licensees. The CLIIP directs the NRC staff to evaluate any comments received for a proposed change to the STS and to either reconsider the change or announce the availability of the change for adoption by licensees. This notice involves the modification of LCO 3.10.1. The proposed changes would revise LCO 3.10.1, and the associated Bases, to expand its scope to include provisions for temperature excursions greater than [200] °F as a consequence of inservice leak and hydrostatic testing, and as a consequence of scram time testing initiated in conjunction with an inservice leak or hydrostatic test, while considering operational conditions to be in Mode 4. This change was proposed for incorporation into the standard technical specifications by the owners groups participants in the Technical Specification Task Force (TSTF) and is designated TSTF–484. TSTF–484 can be viewed on the NRC’s web page utilizing the Agencywide Documents Access and Management System (ADAMS). ADAMS accession numbers are ML052930102 (TSTF–484 Submittal), ML060970568 (NRC Request for Additional Information, RAI), ML061560523 (TSTF Response to NRC RAIs), and ML062650171 (TSTF Response to NRC Notice for Comment). 16:53 Oct 26, 2006 Jkt 211001 Licensees opting to apply for this TS change are responsible for reviewing the staff’s evaluation, referencing the applicable technical justifications, and providing any necessary plant-specific information. Each amendment application made in response to the notice of availability will be processed and noticed in accordance with applicable rules and NRC procedures. Public Notices Background VerDate Aug<31>2005 Applicability In a notice in the Federal Register dated August 21, 2006 (71 FR 48561), the staff requested comment on the use of the CLIIP to process requests to revise the TS regarding LCO 3.10.1, ‘‘Inservice Leak and Hydrostatic Testing Operation.’’ In addition, there have been several plant-specific amendment requests to adopt changes similar to those described in TSTF–484 and notices have been published for these applications. TSTF–484, as well as the NRC staff’s safety evaluation and model application, may be examined, and/or copied for a fee, at the NRC/s Public Document Room, located at One White Flint North, 11555 Rockville Pike (first floor), Rockville, Maryland. Publicly available records are accessible electronically from the ADAMS Public Library component on the NRC Web site, (the Electronic Reading Room). The staff received one response with seven comments following the notice published August 21, 2006 (71 FR 48561), soliciting comments on the model SE and NSHC determination related to TSTF–484, Revision 0. The comments were offered by the TSTF in a letter dated September 20, 2006 (ADAMS# ML062650171). The comments are administrative in nature in that they provide clarification and do not have a material impact on the model SE and NSHC determination published August 21, 2006 (71 FR 48561). TSTF comments that were incorporated include the comment on the Federal Register Notice for Comment and comments 1, 3, 4, and 5 on the Model Safety Evaluation. The TSTF has been informed of NRC staff decision not to incorporate comments 2 and 6. Comment 2 provides for additional information about TSTF–484 regarding scram time testing to be included in paragraph one of section 3.0. In the original Model Safety Evaluation published for comment on August 21, 2006 (71 FR 48561), the first half of section 3.0 discusses hydrostatic and leakage testing, while the second half of section 3.0 discusses scram time testing. NRC staff believe that there may be confusion if the comment is PO 00000 Frm 00067 Fmt 4703 Sfmt 4703 63051 incorporated into the first section of 3.0 while scram time testing is not discussed until the second half of section 3.0. The information provided in the comment is captured in the second half of section 3.0. Comment 6 was not incorporated due to possible confusion regarding the term ‘‘conservatively’’. In reviewing the TSTF–484, Revision 0 submittal, the NRC has concluded that there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, such activities will be conducted in compliance with the Commission’s regulations, and the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public. Therefore, it was decided that comment 6 was not needed in order to justify TSTF–484, Revision 0 approval. The revised model SE is included in this notice for use by licensees. As described in the model application prepared by the staff, licensees may reference in their plantspecific applications to adopt TSTF– 484, the SE and NSHC determination.

The proposed changes would revise Limiting Condition for Operation (LCO) 3.10.1, and the associated Bases, to expand its scope to include provisions for temperature excursions greater than [200] °F as a consequence of inservice leak and hydrostatic testing, and as a consequence of scram time testing initiated in conjunction with an inservice leak or hydrostatic test, while considering operational conditions to be in Mode 4. 2.0 Regulatory Evaluation 2.1 Inservice Leak and Hydrostatic Testing. The Reactor Coolant System (RCS) serves as a pressure boundary and also serves to provide a flow path for the circulation of coolant past the fuel. In order to maintain RCS integrity, Section XI of the American Society of Mechanical Engineers (ASME) Pressure Vessel Code requires periodic hydrostatic and leakage testing. Hydrostatic tests are required to be E:\FR\FM\27OCN1.SGM 27OCN1 jlentini on PROD1PC65 with NOTICES 63052 Federal Register / Vol. 71, No. 208 / Friday, October 27, 2006 / Notices performed once every ten years and leakage tests are required to be performed each refueling outage. Appendix G to 10 CFR Part 50 states that pressure tests and leak tests of the reactor vessel that are required by Section XI of the American Society of Mechanical Engineers (ASME) Pressure Vessel Code must be completed before the core is critical. NUREG–1433, General Electric Plants, BWR/4, Revision 3, Standard Technical Specifications (STS) and NUREG–1434, General Electric Plants, BWR/6, Revision 3, STS both currently contain LCO 3.10.1, ‘‘Inservice Leak and Hydrostatic Testing Operation.’’ LCO 3.10.1 was created to allow for hydrostatic and leakage testing to be conducted while in Mode 4 with average reactor coolant temperature greater than [200] °F provided certain secondary containment LCOs are met. TSTF–484, Revision 0, Use of TS 3.10.1 for Scram Time Testing Activities, modifies LCO 3.10.1 to allow a licensee to implement LCO 3.10.1, while hydrostatic and leakage testing is being conducted, should average reactor coolant temperature exceed [200] °F during testing. This modification does not alter current requirements for hydrostatic and leakage testing as required by Appendix G to 10 CFR Part 50. 2.2 Control Rod Scram Time Testing. Control rods function to control reactor power level and to provide adequate excess negative reactivity to shut down the reactor from any normal operating or accident condition at any time during core life. The control rods are scrammed by using hydraulic pressure exerted by the control rod drive (CRD) system. Criterion 10 of Appendix A to 10 CFR part 50 states that the reactor core and associated coolant, control, and protection systems shall be designed with appropriate margin to assure that specified acceptable fuel limits are not exceeded during any condition of normal operation, including the effects of anticipated operational occurrences. The scram reactivity used in design basis accidents (DBA) and transient analyses is based on an assumed control rod scram time. NUREG–1433, General Electric Plants, BWR/4, Revision 3, STS and NUREG– 1434, General Electric Plants, BWR/6, Revision 3, STS both currently contain surveillance requirements (SR) to conduct scram time testing when certain conditions are met in order to ensure that Criterion 10 of Appendix A to 10 CFR Part 50 is satisfied. SR 3.1.4.1 requires scram time testing to be conducted following a shutdown greater VerDate Aug<31>2005 16:53 Oct 26, 2006 Jkt 211001 than 120 days while SR 3.1.4.4 requires scram time testing to be conducted following work on the CRD system or following fuel movement within the affected core cell. Both SRs must be performed at reactor steam dome pressure greater than or equal to [800] psig and prior to exceeding 40 percent rated thermal power (RTP). TSTF–484, Revision 0, Use of TS 3.10.1 for Scram Time Testing Activities, would modify LCO 3.10.1 to allow SR 3.1.4.1 and SR 3.1.4.4 to be conducted in Mode 4 with average reactor coolant temperature greater than [200] °F. Scram time testing would be performed in accordance with LCO 3.10.4, ‘‘Single Control Rod Withdrawal—Cold Shutdown.’’ This modification to LCO 3.10.1 does not alter the means of compliance with Criterion 10 of Appendix A to 10 CFR Part 50. 3.0 Technical Evaluation The existing provisions of LCO 3.10.1 allow for hydrostatic and leakage testing to be conducted while in Mode 4 with average reactor coolant temperature greater than [200] °F, while imposing Mode 3 secondary containment requirements. Under the existing provision, LCO 3.10.1 would have to be implemented prior to hydrostatic and leakage testing. As a result, if LCO 3.10.1 was not implemented prior to hydrostatic and leakage testing, hydrostatic and leakage testing would have to be terminated if average reactor coolant temperature exceeded [200] °F during the conduct of the hydrostatic and leakage test. TSTF–484, Revision 0, Use of TS 3.10.1 for Scram Time Testing Activities, modifies LCO 3.10.1 to allow a licensee to implement LCO 3.10.1, while hydrostatic and leakage testing is being conducted, should average reactor coolant temperature exceed [200] °F during testing. The modification will allow completion of testing without the potential for interrupting the test in order to reduce reactor vessel pressure, cool the RCS, and restart the test below [200] °F. Since the current LCO 3.10.1 allows testing to be conducted while in Mode 4 with average reactor coolant temperature greater than [200] °F, the proposed change does not introduce any new operational conditions beyond those currently allowed. SR 3.1.4.1 and SR 3.1.4.4 require that control rod scram time be tested at reactor steam dome pressure greater than or equal to [800] psig and before exceeding 40 percent rated thermal power (RTP). Performance of control rod scram time testing is typically scheduled concurrent with inservice leak or hydrostatic testing while the PO 00000 Frm 00068 Fmt 4703 Sfmt 4703 RCS is pressurized. Because of the number of control rods that must be tested, it is possible for the inservice leak or hydrostatic test to be completed prior to completing the scram time test. Under existing provisions, if scram time testing can not be completed during the LCO 3.10.1 inservice leak or hydrostatic test, scram time testing must be suspended. Additionally, if LCO 3.10.1 is not implemented and average reactor coolant temperature exceeds [200] °F while performing the scram time test, scram time testing must also be suspended. In both situations, scram time testing is resumed during startup and is completed prior to exceeding 40 percent RTP. TSTF–484, Revision 0, Use of TS 3.10.1 for Scram Time Testing Activities, modifies LCO 3.10.1 to allow a licensee to complete scram time testing initiated during inservice leak or hydrostatic testing. As stated earlier, since the current LCO 3.10.1 allows testing to be conducted while in Mode 4 with average reactor coolant temperature greater than [200] °F, the proposed change does not introduce any new operational conditions beyond those currently allowed. Completion of scram time testing prior to reactor criticality and power operations results in a more conservative operating philosophy with attendant potential safety benefits. It is acceptable to perform other testing concurrent with the inservice leak or hydrostatic test provided that this testing can be performed safely and does not interfere with the leak or hydrostatic test. However, it is not permissible to remain in TS 3.10.1 solely to complete such testing following the completion of inservice leak or hydrostatic testing and scram time testing. Since the tests are performed with the reactor pressure vessel (RPV) nearly water solid, at low decay heat values, and near Mode 4 conditions, the stored energy in the reactor core will be very low. Small leaks from the RCS would be detected by inspections before a significant loss of inventory occurred. In addition, two low-pressure emergency core cooling systems (ECCS) injection/ spray subsystems are required to be operable in Mode 4 by TS 3.5.2, ECCSShutdown. In the event of a large RCS leak, the RPV would rapidly depressurize and allow operation of the low pressure ECCS. The capability of the low pressure ECCS would be adequate to maintain the fuel covered under the low decay heat conditions during these tests. Also, LCO 3.10.1 requires that secondary containment and standby gas treatment system be operable and capable of handling any E:\FR\FM\27OCN1.SGM 27OCN1 Federal Register / Vol. 71, No. 208 / Friday, October 27, 2006 / Notices airborne radioactivity or steam leaks that may occur during performance of testing. The protection provided by the normally required Mode 4 applicable LCOs, in addition to the secondary containment requirements required to be met by LCO 3.10.1, minimizes potential consequences in the event of any postulated abnormal event during testing. In addition, the requested modification to LCO 3.10.1 does not create any new modes of operation or operating conditions that are not currently allowed. Therefore, the staff finds the proposed change acceptable. 4.0 State Consultation In accordance with the Commission’s regulations, the [Name of State] State official was notified of the proposed issuance of the amendment. The State official had [no] comments. [If comments were provided, they should be addressed here]. 5.0 Environmental Consideration The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding issued on [Date] ([ ] FR [ ]). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment. jlentini on PROD1PC65 with NOTICES 6.0 Conclusion The Commission has concluded, based on the considerations discussed above, that: (1) There is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission’s regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

NUCLEAR REGULATORY COMMISSION


Notice of Availability of Model Safety Evaluation on Technical 
Specification Improvement To Modify Requirements Regarding LCO 3.10.1, 
Inservice Leak and Hydrostatic Testing Operation Using the Consolidated 
Line Item Improvement Process

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of availability.

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

SUMMARY: Notice is hereby given that the staff of the Nuclear 
Regulatory Commission (NRC) has prepared a model safety evaluation (SE) 
relating to the modification of shutdown testing requirements in 
technical specifications (TS) for Boiling Water Reactors (BWR). The NRC 
staff has also prepared a model no-significant-hazards-consideration 
(NSHC) determination relating to this matter. The purpose of these 
models is to permit the NRC to efficiently process amendments that 
propose to modify LCO 3.10.1. The proposed changes would revise LCO 
3.10.1, and the associated Bases, to expand its scope to include 
provisions for temperature excursions greater than [200] [deg]F as a 
consequence of inservice leak and hydrostatic testing, and as a 
consequence of scram time testing initiated in conjunction with an 
inservice leak or hydrostatic test, while considering operational 
conditions to be in Mode 4. Licensees of nuclear power reactors to 
which the models apply could then request amendments, confirming the 
applicability of the SE and NSHC determination to their reactors.

DATES: The NRC staff issued a Federal Register notice on August 21, 
2006 (71 FR 48561) that provided a model safety evaluation (SE) and a 
model no significant hazards consideration (NSHC) determination 
relating to modification of requirements regarding LCO 3.10.1, 
``Inservice Leak and Hydrostatic Testing Operation.'' The NRC staff 
hereby announces that the model SE and NSHC determination may be 
referenced in plant-specific applications to adopt the changes. The 
staff will post a model application on the NRC web site to assist 
licensees in using the consolidated line item

SUPPLEMENTARY INFORMATION:

Background

    Regulatory Issue Summary 2000-06, ``Consolidated Line Item 
Improvement Process for Adopting Standard Technical Specification 
Changes for Power Reactors,'' was issued on March 20, 2000. The 
consolidated line item improvement process (CLIIP) is intended to 
improve the efficiency of NRC licensing processes by processing 
proposed changes to the standard technical specifications (STS) in a 
manner that supports subsequent license amendment applications. The 
CLIIP includes an opportunity for the public to comment on a proposed 
change to the STS after a preliminary assessment by the NRC staff and a 
finding that the change will likely be offered for adoption by 
licensees. The CLIIP directs the NRC staff to evaluate any comments 
received for a proposed change to the STS and to either reconsider the 
change or announce the availability of the change for adoption by 
licensees.
    This notice involves the modification of LCO 3.10.1. The proposed 
changes would revise LCO 3.10.1, and the associated Bases, to expand 
its scope to include provisions for temperature excursions greater than 
[200] [deg]F as a consequence of inservice leak and hydrostatic 
testing, and as a consequence of scram time testing initiated in 
conjunction with an inservice leak or hydrostatic test, while 
considering operational conditions to be in Mode 4. This change was 
proposed for incorporation into the standard technical specifications 
by the owners groups participants in the Technical Specification Task 
Force (TSTF) and is designated TSTF-484. TSTF-484 can be viewed on the 
NRC's web page utilizing the Agencywide Documents Access and Management 
System (ADAMS). ADAMS accession numbers are ML052930102 (TSTF-484 
Submittal), ML060970568 (NRC Request for Additional Information, RAI), 
ML061560523 (TSTF Response to NRC RAIs), and ML062650171 (TSTF Response 
to NRC Notice for Comment).

Applicability

    Licensees opting to apply for this TS change are responsible for 
reviewing the staff's evaluation, referencing the applicable technical 
justifications, and providing any necessary plant-specific information. 
Each amendment application made in response to the notice of 
availability will be processed and noticed in accordance with 
applicable rules and NRC procedures.

Public Notices

    In a notice in the Federal Register dated August 21, 2006 (71 FR 
48561), the staff requested comment on the use of the CLIIP to process 
requests to revise the TS regarding LCO 3.10.1, ``Inservice Leak and 
Hydrostatic Testing Operation.'' In addition, there have been several 
plant-specific amendment requests to adopt changes similar to those 
described in TSTF-484 and notices have been published for these 
applications. TSTF-484, as well as the NRC staff's safety evaluation 
and model application, may be examined, and/or copied for a fee, at the 
NRC/s Public Document Room, located at One White Flint North, 11555 
Rockville Pike (first floor), Rockville, Maryland. Publicly available 
records are accessible electronically from the ADAMS Public Library 
component on the NRC Web site, (the Electronic Reading Room).
    The staff received one response with seven comments following the 
notice published August 21, 2006 (71 FR 48561), soliciting comments on 
the model SE and NSHC determination related to TSTF-484, Revision 0. 
The comments were offered by the TSTF in a letter dated September 20, 
2006 (ADAMS ML062650171). The comments are administrative in 
nature in that they provide clarification and do not have a material 
impact on the model SE and NSHC determination published August 21, 2006 
(71 FR 48561). TSTF comments that were incorporated include the comment 
on the Federal Register Notice for Comment and comments 1, 3, 4, and 5 
on the Model Safety Evaluation. The TSTF has been informed of NRC staff 
decision not to incorporate comments 2 and 6. Comment 2 provides for 
additional information about TSTF-484 regarding scram time testing to 
be included in paragraph one of section 3.0. In the original Model 
Safety Evaluation published for comment on August 21, 2006 (71 FR 
48561), the first half of section 3.0 discusses hydrostatic and leakage 
testing, while the second half of section 3.0 discusses scram time 
testing. NRC staff believe that there may be confusion if the comment 
is incorporated into the first section of 3.0 while scram time testing 
is not discussed until the second half of section 3.0. The information 
provided in the comment is captured in the second half of section 3.0. 
Comment 6 was not incorporated due to possible confusion regarding the 
term ``conservatively''. In reviewing the TSTF-484, Revision 0 
submittal, the NRC has concluded that there is reasonable assurance 
that the health and safety of the public will not be endangered by 
operation in the proposed manner, such activities will be conducted in 
compliance with the Commission's regulations, and the issuance of the 
amendment will not be inimical to the common defense and security or to 
the health and safety of the public. Therefore, it was decided that 
comment 6 was not needed in order to justify TSTF-484, Revision 0 
approval. The revised model SE is included in this notice for use by 
licensees. As described in the model application prepared by the staff, 
licensees may reference in their plant-specific applications to adopt 
TSTF-484, the SE and NSHC determination.

Task Force Change TSTF-484, Revision 0, Use of TS 3.10.1 for Scram Time 
Testing Activities

1.0 Introduction
    By application dated [Date], [Name of Licensee] (the licensee) 
requested changes to the Technical Specifications (TS) for the [Name of 
Facility].
    The proposed changes would revise Limiting Condition for Operation 
(LCO) 3.10.1, and the associated Bases, to expand its scope to include 
provisions for temperature excursions greater than [200] [deg]F as a 
consequence of inservice leak and hydrostatic testing, and as a 
consequence of scram time testing initiated in conjunction with an 
inservice leak or hydrostatic test, while considering operational 
conditions to be in Mode 4.
2.0 Regulatory Evaluation
    2.1 Inservice Leak and Hydrostatic Testing. The Reactor Coolant 
System (RCS) serves as a pressure boundary and also serves to provide a 
flow path for the circulation of coolant past the fuel. In order to 
maintain RCS integrity, Section XI of the American Society of 
Mechanical Engineers (ASME) Pressure Vessel Code requires periodic 
hydrostatic and leakage testing. Hydrostatic tests are required to be

[[Page 63052]]

performed once every ten years and leakage tests are required to be 
performed each refueling outage. Appendix G to 10 CFR Part 50 states 
that pressure tests and leak tests of the reactor vessel that are 
required by Section XI of the American Society of Mechanical Engineers 
(ASME) Pressure Vessel Code must be completed before the core is 
critical.
    NUREG-1433, General Electric Plants, BWR/4, Revision 3, Standard 
Technical Specifications (STS) and NUREG-1434, General Electric Plants, 
BWR/6, Revision 3, STS both currently contain LCO 3.10.1, ``Inservice 
Leak and Hydrostatic Testing Operation.'' LCO 3.10.1 was created to 
allow for hydrostatic and leakage testing to be conducted while in Mode 
4 with average reactor coolant temperature greater than [200] [deg]F 
provided certain secondary containment LCOs are met.
    TSTF-484, Revision 0, Use of TS 3.10.1 for Scram Time Testing 
Activities, modifies LCO 3.10.1 to allow a licensee to implement LCO 
3.10.1, while hydrostatic and leakage testing is being conducted, 
should average reactor coolant temperature exceed [200] [deg]F during 
testing. This modification does not alter current requirements for 
hydrostatic and leakage testing as required by Appendix G to 10 CFR 
Part 50.
    2.2 Control Rod Scram Time Testing. Control rods function to 
control reactor power level and to provide adequate excess negative 
reactivity to shut down the reactor from any normal operating or 
accident condition at any time during core life. The control rods are 
scrammed by using hydraulic pressure exerted by the control rod drive 
(CRD) system. Criterion 10 of Appendix A to 10 CFR part 50 states that 
the reactor core and associated coolant, control, and protection 
systems shall be designed with appropriate margin to assure that 
specified acceptable fuel limits are not exceeded during any condition 
of normal operation, including the effects of anticipated operational 
occurrences. The scram reactivity used in design basis accidents (DBA) 
and transient analyses is based on an assumed control rod scram time.
    NUREG-1433, General Electric Plants, BWR/4, Revision 3, STS and 
NUREG-1434, General Electric Plants, BWR/6, Revision 3, STS both 
currently contain surveillance requirements (SR) to conduct scram time 
testing when certain conditions are met in order to ensure that 
Criterion 10 of Appendix A to 10 CFR Part 50 is satisfied. SR 3.1.4.1 
requires scram time testing to be conducted following a shutdown 
greater than 120 days while SR 3.1.4.4 requires scram time testing to 
be conducted following work on the CRD system or following fuel 
movement within the affected core cell. Both SRs must be performed at 
reactor steam dome pressure greater than or equal to [800] psig and 
prior to exceeding 40 percent rated thermal power (RTP).
    TSTF-484, Revision 0, Use of TS 3.10.1 for Scram Time Testing 
Activities, would modify LCO 3.10.1 to allow SR 3.1.4.1 and SR 3.1.4.4 
to be conducted in Mode 4 with average reactor coolant temperature 
greater than [200] [deg]F. Scram time testing would be performed in 
accordance with LCO 3.10.4, ``Single Control Rod Withdrawal--Cold 
Shutdown.'' This modification to LCO 3.10.1 does not alter the means of 
compliance with Criterion 10 of Appendix A to 10 CFR Part 50.
3.0 Technical Evaluation
    The existing provisions of LCO 3.10.1 allow for hydrostatic and 
leakage testing to be conducted while in Mode 4 with average reactor 
coolant temperature greater than [200] [deg]F, while imposing Mode 3 
secondary containment requirements. Under the existing provision, LCO 
3.10.1 would have to be implemented prior to hydrostatic and leakage 
testing. As a result, if LCO 3.10.1 was not implemented prior to 
hydrostatic and leakage testing, hydrostatic and leakage testing would 
have to be terminated if average reactor coolant temperature exceeded 
[200] [deg]F during the conduct of the hydrostatic and leakage test. 
TSTF-484, Revision 0, Use of TS 3.10.1 for Scram Time Testing 
Activities, modifies LCO 3.10.1 to allow a licensee to implement LCO 
3.10.1, while hydrostatic and leakage testing is being conducted, 
should average reactor coolant temperature exceed [200] [deg]F during 
testing. The modification will allow completion of testing without the 
potential for interrupting the test in order to reduce reactor vessel 
pressure, cool the RCS, and restart the test below [200] [deg]F. Since 
the current LCO 3.10.1 allows testing to be conducted while in Mode 4 
with average reactor coolant temperature greater than [200] [deg]F, the 
proposed change does not introduce any new operational conditions 
beyond those currently allowed.
    SR 3.1.4.1 and SR 3.1.4.4 require that control rod scram time be 
tested at reactor steam dome pressure greater than or equal to [800] 
psig and before exceeding 40 percent rated thermal power (RTP). 
Performance of control rod scram time testing is typically scheduled 
concurrent with inservice leak or hydrostatic testing while the RCS is 
pressurized. Because of the number of control rods that must be tested, 
it is possible for the inservice leak or hydrostatic test to be 
completed prior to completing the scram time test. Under existing 
provisions, if scram time testing can not be completed during the LCO 
3.10.1 inservice leak or hydrostatic test, scram time testing must be 
suspended. Additionally, if LCO 3.10.1 is not implemented and average 
reactor coolant temperature exceeds [200] [deg]F while performing the 
scram time test, scram time testing must also be suspended. In both 
situations, scram time testing is resumed during startup and is 
completed prior to exceeding 40 percent RTP. TSTF-484, Revision 0, Use 
of TS 3.10.1 for Scram Time Testing Activities, modifies LCO 3.10.1 to 
allow a licensee to complete scram time testing initiated during 
inservice leak or hydrostatic testing. As stated earlier, since the 
current LCO 3.10.1 allows testing to be conducted while in Mode 4 with 
average reactor coolant temperature greater than [200] [deg]F, the 
proposed change does not introduce any new operational conditions 
beyond those currently allowed. Completion of scram time testing prior 
to reactor criticality and power operations results in a more 
conservative operating philosophy with attendant potential safety 
benefits.
    It is acceptable to perform other testing concurrent with the 
inservice leak or hydrostatic test provided that this testing can be 
performed safely and does not interfere with the leak or hydrostatic 
test. However, it is not permissible to remain in TS 3.10.1 solely to 
complete such testing following the completion of inservice leak or 
hydrostatic testing and scram time testing.
    Since the tests are performed with the reactor pressure vessel 
(RPV) nearly water solid, at low decay heat values, and near Mode 4 
conditions, the stored energy in the reactor core will be very low. 
Small leaks from the RCS would be detected by inspections before a 
significant loss of inventory occurred. In addition, two low-pressure 
emergency core cooling systems (ECCS) injection/spray subsystems are 
required to be operable in Mode 4 by TS 3.5.2, ECCS-Shutdown. In the 
event of a large RCS leak, the RPV would rapidly depressurize and allow 
operation of the low pressure ECCS. The capability of the low pressure 
ECCS would be adequate to maintain the fuel covered under the low decay 
heat conditions during these tests. Also, LCO 3.10.1 requires that 
secondary containment and standby gas treatment system be operable and 
capable of handling any

[[Page 63053]]

airborne radioactivity or steam leaks that may occur during performance 
of testing.
    The protection provided by the normally required Mode 4 applicable 
LCOs, in addition to the secondary containment requirements required to 
be met by LCO 3.10.1, minimizes potential consequences in the event of 
any postulated abnormal event during testing. In addition, the 
requested modification to LCO 3.10.1 does not create any new modes of 
operation or operating conditions that are not currently allowed. 
Therefore, the staff finds the proposed change acceptable.
4.0 State Consultation
    In accordance with the Commission's regulations, the [Name of 
State] State official was notified of the proposed issuance of the 
amendment. The State official had [no] comments. [If comments were 
provided, they should be addressed here].
5.0 Environmental Consideration
    The amendment changes a requirement with respect to installation or 
use of a facility component located within the restricted area as 
defined in 10 CFR Part 20. The NRC staff has determined that the 
amendment involves no significant increase in the amounts, and no 
significant change in the types, of any effluents that may be released 
offsite, and that there is no significant increase in individual or 
cumulative occupational radiation exposure. The Commission has 
previously issued a proposed finding that the amendment involves no 
significant hazards consideration, and there has been no public comment 
on such finding issued on [Date] ([ ] FR [ ]). Accordingly, the 
amendment meets the eligibility criteria for categorical exclusion set 
forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no 
environmental impact statement or environmental assessment need be 
prepared in connection with the issuance of the amendment.
6.0 Conclusion
    The Commission has concluded, based on the considerations discussed 
above, that: (1) There is reasonable assurance that the health and 
safety of the public will not be endangered by operation in the 
proposed manner, (2) such activities will be conducted in compliance 
with the Commission's regulations, and (3) the issuance of the 
amendment will not be inimical to the common defense and security or to 
the health and safety of the public.
