Acceptance Review Results for Browns Ferry Nuclear Plant, Units 1, 2, and 3, Alternative Request 0-ISI-47 to Use an Alternative to ASME Code,Section XI, Examination Requirements for Examination Categories B-N-1 and B-N-2 (EPID L-2023-LLR-0034)

Dear Mr. Eckermann:

By letter dated July 3, 2023 (ADAMS Accession No. ML23184A142), Tennessee Valley Authority (TVA) requested an alternative (i.e., 0-ISI-47) to American Society of Mechanical Engineers Boiler and Pressure Vessel Code,Section XI Table IWB -2500-1, Examination Category B-N-1 and B-N-2 requirements, in accordance with 10 CFR 50.55a(z)(1), for Browns Ferry Nuclear Plant, Units 1, 2, and 3. The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this alternative request. 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 request has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

Pursuant to 10 CFR 50.55a(z)(1) and 50.55a(z)(2), the applicant shall demonstrate that the proposed alternatives would provide an acceptable level of quality and safety, or that compliance with the specified requirements of Section 50.55a would result in hardship or unusual difficulty without a compensating increase in the level of quality or safety.

The NRC staff has reviewed your request 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 request in terms of regulatory requirements. 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. If additional information is needed, you will be advised by separate correspondence.

Based on the information provided in TVAs submittal, the NRC staff has estimated that it will take approximately 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> to complete, and that the review can be completed by July 26, 2024. The estimate is based on the staffs initial review of the request and could change, due to several factors including request for additional information and unanticipated addition of scope to the review. 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 our routine interactions.

If you have any questions, please email, or contact me at (301) 415-1627.

Sincerely, Kimberly Green, Senior Project Manager Plant Licensing Branch II-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation
