LRA Section A.2.1.11, Fatigue Monitoring Program, is revised as follows.
The Fatigue Monitoring Program is an existing program that tracks the number of critical thermal and pressure transients for selected reactor coolant system components. The program ensures the validity of analyses that explicitly analyzed a specified number of fatigue transients by assuring that the actual effective number of transients does not exceed the analyzed number of transients. The program provides for update of the fatigue usage calculations to maintain a CUF of < 1.0 for the period of extended operation. For the locations identified in Section A.2.2.2.3, updated calculations will account for the effects of the reactor water environment. These calculation updates 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
NL-08-021 Attachment I Docket Nos. 50-247 & 50-286 Page 3 of 6 the fatigque analyses. The program requires corrective actions including repair or replacement of affected components before fatigue usage calculations determine the CUF exceeds 1.0. Specific corrective actions are implemented in accordance with the IPEC corrective action program. Repair or replacement of the affected component(s), if necessary, 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 pro-gram and meet the applicable repair or replacement requirements of the ASME Code Section Xl.
LRA Section A.2.2.2.3, Environmental Effects on Fatigue, is revised as follows.
The effects of reactor water environment on fatigue were evaluated for license renewal.
Projected cumulative usage factors (CUFs) were calculated for the limiting locations identified-in-based on NUREG/CR-6260. The identified IP2 locations are those listed in the license renewal application, Table 4.3-13. For the locsations with CU, s less, than 1.0, the 64.24(G)(1)(ii).Several locations may exceed a CUF of 1.0 with consideration of environmental effects during the period of extended operation.

LRA Section A.3.2.2.3, Environmental Effects on Fatigue, is revised as follows.
The effects of reactor water environment on fatigue were evaluated for license renewal.
Projected cumulative usage factors (CUFs) were calculated for the limiting locations idenfifldir based on NUREG/CR-6260. The identified IP3 locations are those listed in the license renewal application, Table 4.3-14. For the lcsations With CU.s less than 1.0, the TLAA. has been projected through the period of extended oporation per 10 CFR 5424(o)(4)(ii).

Should !PEG select the option to manage the aging effects due to environmnental assisted fatigue during the period of extended operation, details ofthe agn aagement-PFOgFa such as scope, qualification, method, and frequency will be submttd16d to the NRC at least 2 years prorF to the period of extended operation-.
LRA Section B.1.12, Fatigue Monitoring, Program Description, is revised as follows.
The Fatigue Monitoring Program is an existing program that tracks the number of critical thermal and pressure transients for selected reactor coolant system components. The program ensures the validity of analyses that explicitly analyzed a specified number of fatigue transients by assuring that the actual effective number of transients does not exceed the analyzed number of transients.
The pro-gram provides for update of the fatigue usage calculations to maintain a CUF of <
1.0 for the period of extended operation. For the locations identified in LRA Table 4.3-13 (1P2) and LRA Table 4.3-14 (IP3), updated calculations will account for the effects of the reactor water environment. These calculation updates are governed by Enter-gy's 10 CFR 50 Appendix B Quality Assurance (QA) program and include design input verification and
NL-08-021 Attachment I Docket Nos. 50-247 & 50-286 Page 6 of 6 independent reviews ensuring that valid assumptions, transients, cycles, external loadings, analysis methods, and environmental fatigue life correction factors will be used in the fatigue analyses.
The analysis methods for determination of stresses and fatigue usage will be in accordance 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. IPEC will utilize design transients from IPEC Design Specifications to bound all operational transients. The numbers of cycles used for evaluation will be based on the design number of cycles and actual IPEC cycle counts proiected out to the end of the license renewal period (60 years).
Environmental effects on fatigue usage will be assessed using methodology consistent with the Generic Aging Lessons Learned Report, NUREG-1 801, Rev. 1, (GALL) 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 steels."
The Fatigue Monitoring Program tracks actual plant transients and evaluates these against the design transients. Cycle counts show no limits are expected to be approached for the current license term. The Fatigue Monitoring Program will ensure that the numbers of transient cycles experienced by the plant remain within the analyzed numbers of cycles and hence, the component CUFs remain below the values calculated in the design basis fatigue evaluations. If ongoing monitoring indicates the potential for a condition outside that analyzed above, IPEC may perform further reanalysis of the identified configuration using established configuration management processes as described above.
The program requires corrective actions including repair or replacement of affected components before fatigue usage calculations determine the CUF exceeds 1.0. Specific corrective actions are implemented in accordance with the IPEC corrective action program. Repair or replacement of the affected component(s), if necessary, 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 or replacement requirements
