Acceptance Review Results Regarding Request to Revise ISP Schedule for Browns Ferry Nuclear Plant, Unit 2 (EPID L-2025-LLL-0014)

Dear Mr. Palm:
By letter dated July 28, 2025 (Agencywide Documents Access and Management System Accession No. ML25209A578), the Electric Power Research Institute (EPRI) submitted a request to revise the reactor vessel capsule withdrawal schedule for the Browns Ferry Nuclear Plant, Unit 2.
The purpose of this email is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this request. The acceptance review was performed to determine whether the scope and depth of the technical information was sufficient 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 Appendix H, Reactor Vessel Material Surveillance Program Requirements, to Part 50, Domestic Licensing of Production and Utilization Facilities, of Title 10 of the Code of Federal Regulations (10 CFR), a proposed withdrawal schedule must be submitted with a technical justification as specified in 10 CFR 50.4 and must be approved prior to implementation.
The NRC staff has reviewed EPRIs 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 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, 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br />, and 104 days to complete. To support a more efficient process, the NRC is setting a goal of achieving at least a 15% improvement. Based on that, our estimate for this review is 51 hours5.902778e-4 days <br />0.0142 hours <br />8.43254e-5 weeks <br />1.94055e-5 months <br /> and completion by December 19, 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 to you.
If you have any questions, please contact me at (301) 415-1627.
Sincerely, Kimberly J. Green, Senior Project Manager Plant Licensing Branch II-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation
