Acceptance Review Vogtle 3 and 4 - License Amendment Request: Changes to Technical Specification 3.7.6, Main Control Room Emergency Habitability System (VES) Surveillance Requirement L-2024-LLA-0083

Wes and DeLisa,

By letter dated June 21, 2024 (ADAMS Accession No. ML24173A220), Southern Nuclear Operating Company (SNC) submitted a license amendment request (LAR) for Vogtle Electric Generating Plant, Units 3 and 4. The proposed amendment revises COL Appendix A, Technical Specifications (TS) 3.7.6, Main Control Room Emergency Habitability System (VES)

Surveillance Requirement (SR) 3.7.6.5 to refer to the Compressed Gas Association CGA G-7.1, Commodity Specification for Air, Grade E, for the requirements for acceptable compressed air quality in the main control room emergency habitability system (VES) air storage tanks. The LAR also proposes a clarifying change to TS 3.7.6 Action E to provide a more specific description of the VES inoperable condition due to compressed air storage tank volume below the limit.

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 application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

Pursuant to Sections 50.55a(z)(1) and 50.55a(z)(2) of Title 10 of the Code of Federal Regulations (10 CFR), 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 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, and discussions during the pre-licensing meeting on September 28, 2023 (ML23272A182), the NRC staff has estimated that this licensing request will take approximately 240 hours0.00278 days <br />0.0667 hours <br />3.968254e-4 weeks <br />9.132e-5 months <br /> to complete. The NRC staff expects to complete this review by July 16, 2025. 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 or John Lamb.
