Entergy Fleet (ANO, Grand Gulf, River Bend, and Waterford) - Acceptance Review for RR EN-20-RR-003, Proposed Alternative to Use ASME Code Case N-711-2 (EPID L-2020-LLR-0160)

By letter dated December 30, 2020 (Agencywide Documents Access and Management System Accession No. ML20365A088), Entergy Operations, Inc. (Entergy) submitted a relief request (RR) associated with the lnservice Inspection (ISI) Programs for Entergy sites of Arkansas Nuclear One, Units 1 and 2 (ANO);

Grand Gulf Nuclear Station, Unit 1 (Grand Gulf); River Bend Station, Unit 1 (River Bend); and Waterford Steam Electric Station, Unit 3 (Waterford). This request proposes to implement the American Society of Mechanical Engineers (ASME) Code Case N-711-2, "Alternative Examination Coverage Requirements for Examination Category B-F, B-J, C-F-1, C-F-2, and R-A Piping Welds,Section XI, Division 1." This Code Case revision was approved by the ASME Board of Nuclear Codes and Standards in May 2020.

All Entergy sites utilize ASME Code Case N-716-1, Alternative Classification and Examination Requirements, for their risk-informed approach to ISI selection and examination. ASME Code Case N-716-1, Table 1, provides the examination volume for components based upon degradation mechanism.

ASME Code Case N-711-2 provides an alternative examination volume based upon an individual components configuration and its susceptibility to degradation. The degradation mechanisms identified in N-711-2 have also been determined in the ASME Code Case N-716-1 process will be carried forward and applied as allowed by ASME Code Case N-711-2. The use of Code Case N-711-2 does not impact the examination requirements provided in N-716-1..

The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review for the RR. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed RR in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. You will be advised of any further information needed to support the NRC staffs detailed technical review by separate correspondence.

Based on the information provided in your submittal, the NRC staff has estimated that this licensing request will take approximately 160 hours0.00185 days <br />0.0444 hours <br />2.645503e-4 weeks <br />6.088e-5 months <br /> to complete. The NRC staff expects to complete this review by January 21, 2022, or earlier. If there are emergent complexities or challenges in our review that

would cause changes to the initial forecasted completion date or significant changes in the forecasted hours, the reasons for the changes, along with the new estimates, will be communicated during the routine interactions with the assigned project manager. These estimates are based on the NRC staffs initial review of the application and they could change, due to several factors including requests for additional information, or unanticipated addition of scope to the review.

If you have any questions, please contact me at (301) 415-1564.
