3-1SECTION 3AGING MANAGEMENT REVIEW RESULTS3.0 Applicant's Use of the Generic Aging Lessons Learned Report3.0.3 Aging Management Programs3.0.3.2 AMPs That Are Consistent with the GALL Report with Exceptions and/orEnhancements3.0.3.2.9 Fatigue Monitoring ProgramSummary of Technical Information in the Application. LRA Section B.1.12, "Fatigue Monitoring,"describes the existing Fatigue Monitoring Program as consistent, with exceptions, with GALL AMP X.M1, "Metal Fatigue of Reactor Coolant Pressure Boundary."In order not to exceed design limits for fatigue, the Fatigue Monitoring Program tracks thenumber of critical thermal and pressure transients for selected reactor coolant system components and confirms the validity of analyses that explicitly assume a specified number of such fatigue transients by ensuring that the actual effective number of transients is not exceeded.Staff Evaluation. During its audit and review, the staff confirmed the applicant's claim ofconsistency with the GALL Report and documented a detailed audit evaluation of this AMP in Audit and Review Report Section 3.0.3.2.9.The staff reviewed those portions of the Fatigue Monitoring Program for which the applicantclaimed consistency with GALL AMP X.M1 and found them consistent. In a letter dated August 28, 2007, the applicant amended the LRA with respect to its basis forits environmentally-assisted fatigue analysis. In this letter, the applicant clarified that Option 1 of Commitment No. 31 for refined CUF calculations is consistent with the Nuclear Regulatory Commission's (NRC) recommendations for the periodic CUF updates in the "monitoring and trending" (i.e., program element 4) of GALL AMP X.M1, "Metal Fatigue of the Reactor Coolant Pressure Boundary," and that Options 2 and 3 of Commitment No. 31 are considered to be corrective actions that are consistent with the corrective actions recommended in the "corrective action" (i.e., program element 7) of the same GALL AMP. Based on these clarifications, the applicant amended the LRA to bring Commitment No. 31 within the scope of the applicant's Fatigue Monitoring Program and to credit this AMP as the basis for accepting this TLAA in accordance with 10 CFR 54.21(c)(1)(iii). In the LRA amendment, the applicant also stated that the Fatigue Monitoring Program is consistent with GALL AMP X.M1, "Metal Fatigue of the Reactor Coolant Pressure Boundary," without exception. The staff determined that the changes proposed by the applicant are consistent with the NRC's recommendations in GALL AMP X.M1, "Metal Fatigue of the Reactor Coolant Pressure Boundary." Based on this assessment, the staff concludes that the Fatigue Monitoring Program is consistent with GALL AMP X.M1 without exception and is acceptable.

3-2Operating Experience. LRA Section B.1.12 states that industry experience has been factoredinto the Fatigue Monitoring Program through incorporation of regulatory guides and boiling water reactor vessel and internals program documents. The locations at which cumulative usage factors are calculated include those indicated in NUREG/CR-6260. Thermal stresses have been evaluated by the applicant and the applicant will continue to evaluate future plant and industry experience with fatigue of Class 1 components. Recent reactor shutdown and startup cycles did not trend toward exceeding the projected number of cycles, demonstrating that the program successfully monitors plant transients and tracks their accumulation.The staff reviewed the operating experience presented in the LRA and interviewed theapplicant's technical personnel to confirm that the plant-specific operating experience revealed no degradation not bounded by industry experience.The staff confirmed that the "operating experience" program element satisfies the criteriondefined in the GALL Report and in Standard Review Plan for License Renewal Section A.1.2.3.10. The staff finds this program element acceptable.UFSAR Supplement. In LRA Section A.2.1.12, the applicant provided the UFSAR supplementfor the Fatigue Monitoring Program. The staff reviewed this section and determined that the information in the UFSAR supplement is an adequate summary description of the program, as required by 10 CFR 54.21(d).

Conclusion. On the basis of its audit and review of the applicant's Fatigue Monitoring Program,the staff determines that those program elements for which the applicant claimed consistency with GALL AMP X.M1, "Metal Fatigue of Reactor Coolant Pressure Boundary," are consistent.

The staff concludes that the applicant has demonstrated that the effects of aging will be adequately managed so that the intended function(s) will be maintained consistent with the CLB for the period of extended operation, as required by 10 CFR 54.21(a)(3). The staff also reviewed the UFSAR supplement for this AMP and concludes that it provides an adequate summary description of the program, as required by 10 CFR 54.21(d).

4-1SECTION 4TIME-LIMITED AGING ANALYSES4.3 Metal Fatigue4.3.3 Effects of Reactor Water Environment on Fatigue Life4.3.3.1 Summary of Technical Information in the ApplicationLicense renewal application (LRA) Section 4.3.3 summarizes the evaluation of effects of reactorwater environments on fatigue life for the period of extended operation. NUREG/CR-6260 "Application of NUREG/CR-5999 Interim Fatigue Curves to Selected Nuclear Power Plant Components," applies fatigue design curves that incorporate environmental effects on several plants and identified locations of interest for consideration of environmental effects.

NUREG/CR-6260 Section 5.7 indicates for Pilgrim Nuclear Power Station (PNPS)-vintage General Electric plants the following component locations as most sensitive to environmental effects. These locations and the associated calculations relate directly to PNPS:

  • reactor vessel shell and lower head
  • reactor recirculation system (RRS) piping (including inlet and outlet nozzles)
  • core spray line reactor vessel nozzle and associated piping
  • feedwater pipingThe applicant evaluated the limiting locations (a total of nine components at these six locations)using the guidance in NUREG-1801, Revision 1, Volume 2, "Generic Aging Lessons Learned (GALL) Report," Chapter X.M1, " Metal Fatigue of the Reactor Coolant Pressure Boundary,"

and in NUREG-1800, Revision 1, "Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants" (SRP-LR), Sections 4.3.1.2, 4.3.2.2, and 4.3.3.2, "Generic Safety Issue." Four of nine components reviewed have an environmentally-adjusted cumulative usage factor (CUF) greater than 1.0. The American Society of Mechanical Engineers (ASME) Code does not require environmental adjustment to fatigue analyses.The applicant stated that, considering environmental effects, prior to the period of extendedoperation for each location that may exceed a 1.0 CUF, the applicant will implement one or more of the following: (1) further refinement of the fatigue analyses to lower the predicted CUFs to less than 1.0, (2) management of fatigue at the affected locations by an inspection program reviewed and approved by the staff (e.g., periodic non-destructive examination of the locationsat intervals to be determined by a method acceptable to the staff), or (3) repair or replacement of the affected components. The applicant stated that, should it opt to manage fatigue during the period of extendedoperation, the aging management program (AMP) will be submitted for Nuclear Regulatory Commission (NRC) review and approval at least two years prior to entering the period of extended operation. The effects of thermal fatigue for the limiting locations indicated in NUREG-6260 have been evaluated.

4-24.3.3.2 Staff EvaluationThe staff reviewed LRA Section 4.3.3 to verify (1) pursuant to Title 10, Section 54.21(c)(1)(i) ofthe Code of Federal Regulations (10 CFR 54.21(c)(1)(i)), that the analyses remain valid for the period of extended operation, (2) pursuant to 10 CFR 54.21(c)(1)(ii), that the analyses have been projected to the end of the period of extended operation, or (3) pursuant to 10 CFR 54.21(c)(1)(iii), that the effects of aging on the intended function(s) will be adequately managed for the period of extended operation.The staff reviewed LRA Section 4.3.3 against SRP-LR Section 4.3.3.2, "Generic Safety Issue".SRP-LR recommends that the license renewal applicant address GSI-190. To assess the impact of the reactor coolant environment on a sample of critical components, the SRP-LR states that the applicant has to address the recommendations as follows:1.The critical components include, as a minimum, those selected in NUREG/CR-6260.2.The sample of critical components has been evaluated by applying environmentalcorrection factors to the existing ASME Code fatigue analyses.3.Formulas for calculating the environmental life correction factors are those contained inNUREG/CR-6583 for carbon and low-alloy steels, and in NUREG/CR-5704 for austenitic stainless steels (SSs), or an approved technical equivalent.In LRA Table 4.3-3, the applicant has evaluated the sample of critical components by applyingenvironmental correction factors to the current design basis ASME Code fatigue analysis.

The staff confirmed that the critical components include those selected in NUREG/CR-6260.

The staff also confirmed that environmental life correction factors are calculated in accordance with those formulas contained in NUREG/CR-6583 for carbon and low-alloy steels, and in NUREG/CR-5704 for austenitic SSs. Therefore, the staff confirmed that PNPS has followed the staff's recommendations to assess the impact of the reactor coolant environment consistent with SRP-LR. During the audit and review, the staff noted that the projected numbers of transient cyclesexceeded the numbers of current design basis transient cycles and that the CUFs were not evaluated based on the numbers of projected cycles. The staff asked why the new CUFs had not been calculated based on the 60-year projected cycles. The applicant responded that PNPS had not intended to imply that the CUFs should be projected out to 60 years in accordance with 10 CFR 50.41(c)(1)(ii). The applicant stated that as long as the cycles are not exceeded, the CUFs do not need to be recalculated. The applicant also stated that the fatigue monitoring program assures that the analyses will be revised to increase the allowable number of cycles before exceeding the number of design basis cycles. The applicant's approach to address this issue is in accordance with 10 CFR 54(c)(1)(iii).During the audit and review, the staff asked the applicant to resolve three issues in LRASection 4.3.3 and LRA Table 4.3-3 as follows:Issue 1. The footnotes in LRA Table 4.3-3 state that generic values for these components werefrom NUREG/CR-6220. The staff asked the applicant whether this statement should refer to NUREG/CR-6260.

4-3In response, the applicant stated that this reference was a typo that should beNUREG/CR-6260. The staff finds the applicant's response acceptable as NUREG/CR-6260 is the correctreference. Issue 1 is resolved.Issue 2. The staff informed the applicant that plant-specific Class 1 component locationsselected for the environmentally-adjusted CUF analysis should be based on the corresponding specific plant vintage assessed in NUREG/CR-6260 and that the plant-specific locations for analysis therefore depend on the compliance of a plant's Class 1 reactor coolant pressure boundary (RCPB) configuration with that analyzed for the corresponding plant design in the topical report. The staff informed the applicant that it could not use the generic NUREG/CR-6260 environmentally-adjusted CUF values for environmentally-adjusted CUF analysis without justification that the plant-specific Class 1 RCPB locations analyzed were the same as those analyzed for the corresponding boiling water reactor (BWR)-designed vintage plant in NUREG/CR-6260.To resolve the issue, the staff asked the applicant to justify its use of the NUREG/CR-6260generic environmentally-adjusted CUF values for the RR outlet nozzle, core spray nozzle safe end, and feedwater piping. In its response dated July 19, 2006, the applicant stated that the environmentally-adjusted CUFvalues for these components were intended as typical values for predicting the effect of the reactor coolant environment on fatigue. The applicant agreed to supplement the LRA to remove the environmentally-adjusted CUF values for the RR outlet nozzle, core spray safe end, and feedwater piping from LRA Table 4.3-3 and to amend the LRA to provide additional environmentally-adjusted fatigue analyses for these components.In its response dated September 13, 2006, the applicant indicated that it had determined that itsdesign basis includes environmentally-adjusted CUF calculations for the RR outlet nozzle, thecore spray nozzle safe-end, and feedwater piping, and submitted a revised table including normal CUF values for these components to the expiration of the current operating license period (i.e., at the end of 40 years), projected CUF values for these components at the expiration of the period of extended operation, and their projected environmentally-adjusted CUF values at the expiration of the period of extended operation. The table also includes the 60-year environmentally-adjusted CUF calculations for all other plant-specific Class 1 components previously analyzed in accordance with ASME Code,Section III CUF calculations.The applicant stated that all CUFs that exceed 1.0 must be recalculated prior to the period of extended operation. The applicant included Commitment No. 31 to address this issue. The staff's resolution of this issue is deferred to the staff's resolution of request for additional information (RAI) 4.3.3-1 which is discussed and evaluated below.Issue 3. The staff asked the applicant for more details on its corrective action implementationplan for locations projected to have 60-year environmentally adjusted CUF values above 1.0.

Specifically, the staff asked the applicant to clarify how the fatigue analyses would be refined further by selection of Option 1 of the corrective action implementation plan. The staff also informed the applicant that it would need to make a commitment in the LRA if Option 2 of the plan, manage the effects of aging, was selected as the course of corrective action for fatigue-induced damage in the components.

4-4In its response dated September 13, 2006, the applicant added Commitment No. 31, stating itwould implement one of several options for the locations indicated in NUREG/CR-6260 for BWRs of the PNPS vintage.In 4.3.3-1 dated July 26, 2007 (ADAMS Accesssion No. ML072000407), the staff requested thatthe applicant provide additional information on the option(s) that will be used for LRA Commitment No. 31 and describe the methodology that will be used for the chosen Commitment No. 31 option(s) in sufficient detail for staff review.In its response dated July 30, 2007 (ADAMS Accession No. ML072190611), the applicantclarified which option would be implemented to fulfill Commitment No. 31 and provided the methodology that would be used to implement the selected option. Commitment No. 31 was revised to state: "At least 2 years prior to entering the period of extended operation, for thelocations identified in NUREG/CR-6260 for BWRs of the PNPS vintage, PNPS will refine our current fatigue analyses to include the effects of reactor water environment and verify that the cumulative usage factors (CUFs) are less than 1.

This includes applying the appropriate Fen [sic] factors to valid CUFs determined in accordance with one of the following: 1.For locations, including NUREG/CR-6260 locations, with existing fatigueanalyses valid for the period of extended operation, use the existing CUF to determine the environmentally adjusted CUF. 2. More limiting PNPS-specific locations with a valid CUF may be added inaddition to the NUREG/CR-6260 locations. 3. Representative CUF values from other plants, adjusted to or envelopingthe PNPS plant specific external loads may be used if demonstratedapplicable to PNPS. 4. An analysis using an NRC-approved version of the ASME code orNRC-approved alternative (e.g., NRC-approved code case) may be performed to determine a valid CUF.During the period of extended operation, PNPS may also use one of thefollowing options for fatigue management if ongoing monitoring indicates a potential for a condition outside the analysis bounds noted above: 1.Update and/or refine the affected analyses described above.

2. Implement an inspection program that has been reviewed and approvedby the NRC (e.g., periodic nondestructive examination of the affected locations at inspection intervals to be determined by a method acceptable to the NRC).

4-5 3. Repair or replace the affected locations before exceeding a CUF of 1.0."In its response dated July 30, 2007, the applicant also provided its implementation detail forthese 3 options as follows:The processes that will be used to develop the calculations for Option (1) areestablished design and configuration management processes. These processes are governed by Entergy's 10 CFR 50 Appendix B Quality Assurance (QA) program and include design input verification and independent reviews ensuring that valid assumptions, transients, cycles, external loadings, analysis methods, and environmental fatigue life correction factors will be used in the refined or new fatigue analyses. The analysis methods for determination of stresses and fatigue usage will be inaccordance with an NRC endorsed Edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section III Rules for Construction of Nuclear Power Plant Components Division 1 Subsection NB, Class 1 Components, Sub articles NB-3200 or NB-3600 as applicable to the specific component. PNPS will utilize design transients from Design Specifications as well as designtransient information from typical BWR-3 references to bound all operational transients.

The numbers of cycles used for evaluation will be based on the design number of cycles and actual cycle counts projected out to the end of license renewal period (60 years). Environmental effect on fatigue usage will be assessed using methodology consistentwith the GALL Report, Rev. 1, that states, " The sample of critical components can be evaluated by applying environmental life correction factors to the existing ASME Code fatigue analyses. Formulae for calculating the environmental life correction factors are contained in NUREG/CR-6583 for carbon and low-alloy steels and in NUREG/CR-5704 for austenitic stainless steel.If Option (2) of Commitment 31 becomes necessary, the inspection programsubmitted for approval by the NRC will be described in terms of the ten elements specified in Branch Technical Position RLSB-1 (NUREG-1800, Appendix A-1).

Parameters monitored will be the presence and sizing of cracks. Frequency of inspection and acceptance criteria will be established such that detection of aging effects will occur before there is a loss of component intended function(s).

The method of inspection will be a qualified volumetric technique based on plant specific and industry-wide operating experience.If Option (3) becomes necessary, repair or replacement of the affectedcomponent(s) will be in accordance with established plant procedures governing repair and replacement activities. These established procedures are governed by Entergy's 10 CFR 50 Appendix B QA Program and meet the applicable repair and replacement requirements of the ASME Code Section XI.In a letter dated August 28, 2007, the applicant amended the LRA with respect to its basis forits environmentally-assisted fatigue analysis. In this letter, the applicant clarified that Option 1 of 4-6Commitment No. 31 for refined CUF calculations is consistent with both the NRC'srecommendations for the periodic CUF updates in the "monitoring and trending" (i.e., program element 4) of GALL AMP X.M1, "Metal Fatigue of the Reactor Coolant Pressure Boundary," and and for "corrective actions" in GALL AMP X.M1. The applicant also clarified that Options 2 and 3 of Commitment No. 31 are considered to be corrective actions that are consistent with the corrective actions recommended in the "corrective action" (i.e., program element 7) of the same GALL AMP. Based on these clarifications, the applicant amended the LRA to bring Commitment No. 31 within the scope of the applicant's Fatigue Monitoring Program and to credit this AMP as the basis for accepting this TLAA in accordance with 10 CFR 54.21(c)(1)(iii).These changes are consistent with the NRC's recommendations in GALL AMP X.M1, "Metal Fatigue of the Reactor Coolant Pressure Boundary," and are acceptable. The following paragraphs provide additional information on why the changes in LRA Amendment No. 20 are acceptable.

The "corrective actions" of GALL Chapter X.M1, "Metal Fatigue of the Reactor Coolant Pressure Boundary," state that acceptable corrective actions include repair of the component, replacement of component, or a more rigorous analysis of the component to demonstrate that the design limit will not be exceeded during the extended period of operation. The staff reviewed the 3 options in Commitment No. 31, which were included in the application as possible corrective actions to address those limiting reactor coolant pressure boundary components with projected environmentally-assisted CUFs in excess of the environmentally-assisted fatigue analysis limit (i.e., 1.0). The staff reviewed the applicant's implementation plan for using Option (1) of Commitment No.31 (i.e., the option for implementation of refined environmentally-assisted CUF calculations), as provided in the applicant's letter of August 28, 2007, against the staff's recommendation in SRP-LR Section 4.3.3.2, "Generic Safety Issues." The staff determined the response to the RAI indicated that the refined environmentally-assisted fatigue calculations would be based on the recommendations for performing environmentally-assisted fatigue calculations in NUREG/CR-6583 for steel components and in NUREG/CR-5704 for stainless steel components and that the methods for determination of stresses and fatigue usage factors would be in accordance with an NRC-endorsed edition of the ASME Code Sect ion III, Division 1,Subsection NB, Subarticles NB-3200 or NB-3600, as applicable to the specific component.

Based on this response, the staff determined that the implementation plan for using Option (1) of the commitment indicates that the applicant will be using NRC-approved methods for reanalysis and that the option is in conformance with the "corrective actions" recommendations in the both the Standard Review Plan for License Renewal SRP-LR and GALL AMP X.M1, "Metal Fatigue of the Reactor Coolant Pressure Boundary. Based on this assessment, that staff concludes that Option (1) of Commitment No. 31 is an acceptable "corrective action" option for this TLAA.In its response to RAI 4.3.3-1, the applicant stated that, if Option (2) of Commitment No. 31 isselected for corrective action, the inspection program for implementing the options would meet the following criteria: (1) the inspection program would be based on the 10 program elements for an AMP, as defined in NRC Branch Position RLSB-1, (2) the AMP would be submitted for NRC review and approval at least two years prior to entering the period of extended operation, and (3) the method of inspection will be based on a qualified volumetric examination technique.

The ASME Code Section XI, Paragraph IWB-3740(a) states that "Appendix L provides procedures that may be used to assess the effects of thermal and mechanical fatigue concerns 4-7on component acceptability for continued service"; the ASME Code Section XI, ParagraphIWB-3740(b) states that "Appendix L provides procedures that may also be used when the calculated fatigue usage exceeds the fatigue usage limit defined in the original Construction Code." Paragraph L-3400 of the ASME Code Section XI, Appendix L states that surface examinations or volumetric examinations of reactor coolant pressure boundary components may be used to verify the acceptability of affected components for further service. Based on this response, the staff determined that the implementation plan for using Option (2) of the commitment conforms to the examination provisions stated in paragraph L-3400 of the ASME Code Section XI, Non-mandatory Appendix L and with "corrective actions" recommended in GALL AMP X.M1, "Metal Fatigue of the Reactor Coolant Pressure Boundary." Based on this assessment, that staff concludes that Option (2) of Commitment No. 31 is an acceptable "corrective action" option for this TLAA.In its response to RAI 4.3.3-1, the applicant stated that Option (3) for repair or replacement ofthe affected locations is a corrective action. The applicant also stated that, if this option is selected for corrective action, the repair or replacement activities would be in compliance with applicable provisions of the ASME Code Section XI. The staff determined that, since the implementation of repair and replacement activities will be based on applicable ASME Code Section XI requirements, Option (3) of Commitment No. 31 is consistent the "corrective actions recommended in GALL AMP X.M1, "Metal Fatigue of the Reactor Coolant Pressure Boundary."

On this basis, the staff concludes that Option (3) of Commitment No. 31 is also an acceptable "corrective action" option for this TLAA.Based on this assessment, the staff concludes that the corrective actions methods discussed inthe applicant's response to RAI 4.3.3-1 and provided in Commitment No. 31 are acceptable because they will be implemented in accordance with NRC-approved methods. Based on this review, the staff concludes that time-limited aging analysis (TLAA) on environmentally-assisted fatigue is acceptable in accordance with 10 CFR 54.21(c)(1)(iii) because the applicant has credited the Fatigue Monitoring Program to manage the effects of aging during the period of extended operation and because the applicant has amended the Fatigue Monitoring program to include the options in Commitment No. 31 for corrective action, as discussed above.

RAI 4.3.3-1 is resolved.4.3.3.3 UFSAR SupplementThe applicant provided an updated final safety analysis report (UFSAR) supplement summarydescription of its TLAA evaluation of effects of reactor water environments on fatigue life in LRA Section A.2.2.2.3. The applicant stated that the effects of the reactor coolant environment on the metal fatigue analysis had been evaluated for the LRA but only for 40 years and not for the period of extended operation. As a result, the staff determined that the initial version of the UFSAR supplement summary description did not describe the TLAA on environmental fatigue adequately because LRA Section A.2.2.2.3 would need an update to refer to LRA Commitment No. 31, which the applicant relies on for acceptance of the TLAA on environmental fatigue.In a letter dated September 13, 2006, the applicant amended the LRA and added CommitmentNo. 31 to address the need for updated, 60-year environmental CUF calculations for plant-specific Class 1 locations that correspond to those analyzed in NUREG-6260. However, the applicant did not revise the LRA Section A.2.2.2.3 summary description to refer to 4-8Commitment No. 31.In a letter dated August 28, 2007, the applicant amended LRA Section A.2.2.2.3 to refer toCommitment No. 31. The staff reviewed the UFSAR supplement summary description in LRA Section A.2.2.2.3 as amended by this letter. On July 30, 2007, the applicant amended Commitment No. 31 as discussed in the response to RAI 4.3.3-1. The staff determined that the summary description of this TLAA was adequate because it complies with that recommended in the SRP-LR UFSAR supplement table and because it has been amended to refer to Commitment No. 31 on the LRA.Based on its review, the staff concludes that LRA Section A.2.2.2.3, as amended by the August 28, 2007, letter, complies with 10 CFR 54.21(d).4.3.3.4 ConclusionOn the basis of its review, as discussed above, the staff concludes that the applicant hasdemonstrated, pursuant to 10 CFR 54.21(c)(1)(iii), that the effects of aging on the intended function(s) will be adequately managed for the period of extended operation. The staff also concludes that the UFSAR supplement contains an appropriate summary description of the TLAA evaluation, as required by 10 CFR 54.21(d).4.8 Conclusion for Time-Limited Aging AnalysesThe staff reviewed the information in LRA Section 4, "Time-Limited Aging Analyses." On thebasis of its review the staff concludes that the applicant has provided an adequate list of TLAAs, as defined in 10 CFR 54.3. Further, the staff concludes that the applicant demonstrated that: (1) the TLAAs will remain valid for the period of extended operation, as required by 10 CFR 54.21(c)(1)(i); (2) the TLAAs have been projected to the end of the period of extended operation, as required by 10 CFR 54.21(c)(1)(ii); or (3) that the aging effects will be adequately managed for the period of extended operation, as required by 10 CFR 54.21(c)(1)(iii). The staff also reviewed the UFSAR supplement for the TLAAs and found that the UFSAR supplement contains descriptions of the TLAAs sufficient to satisfy the requirements of 10 CFR 54.21(d). In addition, the staff concludes, that no plant-specific exemptions are in effect that are based on TLAAs, as required by 10 CFR 54.21(c)(2).With regard to these matters, the staff concludes, that there is reasonable assurance that theactivities authorized by the renewed license will continue to be conducted in accordance with the current licensing basis (CLB), and that any changes made to the CLB, in order to comply with 10 CFR 54.21(c), are in accordance with the Atomic Energy Act of 1954, and the NRC's regulations.
