NRC NOTICE OF ACCEPTANCE: River Bend Station, Unit 1 - License Amendment Request to Revise the Licensing Basis and Minimum Basin Date:
Friday, January 31, 2025 1:31:00 PM By letter dated December 30, 2024, Entergy submitted a proposed amendment that would modify the River Bend Sation, Unit 1, licensing basis through a revision of the Updated Safety Analysis Report (USAR) to credit makeup to the ultimate heat sink (UHS) in less than 30 days to account for system leakage and for operation with both standby service water subsystems in operation. Additionally, the proposed amendment would revise Technical Specification (TS) Surveillance Requirement 3.7.1.1 to increase the minimum UHS cooling tower basin water level to maximize UHS inventory. (ML24365A265). The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this proposed amendment. 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 amendment 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. If additional information is needed, you will be advised by separate correspondence.
Based on the information provided in your submittal, the NRC staff has estimated that this licensing request will take approximately 580 hours0.00671 days <br />0.161 hours <br />9.589947e-4 weeks <br />2.2069e-4 months <br /> to complete. The NRC staff expects to complete this review by January 30, 2026. 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, and unanticipated addition of scope to the review. Additional delay may occur if the submittal is provided to the NRC in advance or in parallel with industry program initiatives or pilot applications.
If you have any questions, please contact me.
