Dear Ms. Aboulfaida:
By \
letter dated September 18, 2025 (Agencywide Documents Access and Management System Accession No. ML25261A131), Tennessee Valley Authority (TVA) submitted Alternative Request BFN-IST-06 for Browns Ferry Nuclear Plant, Unit 3, regarding Group B quarterly pump testing for standby liquid control pumps 3A and 3B.
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)(2) of Title 10 of the Code of Federal Regulations, the applicant must demonstrate that compliance with the specified requirements would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety.
The NRC staff has reviewed TVAs 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.
The NRC staff has evaluated precedence related to this request and determined that the previous reviews for similar requests required, on average, 59.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />, and 181 days to complete.
However, to support a more efficient process, the NRC is setting a goal of achieving at least a 15% improvement over the initial estimates. Based on that target, the goal for this review is 50 hours5.787037e-4 days <br />0.0139 hours <br />8.267196e-5 weeks <br />1.9025e-5 months <br /> and we plan to complete the review by your requested date of October 17, 2025.
These estimates are based on the staffs initial review of the request and could change, due to several factors including requests 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 contact me at (301) 415-1627.
