SNC Fleet License Amendment Request for Changes to Emergency Action Level Scheme January 7, 2026
Introduction
- By letter dated September 30, 2025 (ML25ML25273A375),
Southern Nuclear Operating Company (SNC) submitted a license amendment request (LAR) for the SNC Fleet.
- The proposed LAR would change the emergency action level (EAL) schemes to adopt Nuclear Energy Institute (NEI) 99-01, Revision 7, September 2024, Development of Emergency Action Levels for Non-Passive Reactors, (ML24274A312) to replace the EAL schemes for the facilities above that are currently based on NEI 99-01, Revision 6. For Vogtle Units 3 and 4, SNC proposes a unique EAL scheme that combines NEI 99-01, Rev. 7, with additional EALs that accommodate the passive features of the AP-1000 design.

Introduction - Continued
- The Federal Government was shutdown from October 1 to November 12, 2025.
- On December 19, 2025 (ML25353A552), this public meeting was noticed.
- On December 30, 2025 (Ml25346A274), NRC issued letter for supplemental information.

Supplemental Info Needed The LAR does not conspicuously identify variances from NEI 99-01, Revision 7 or provide sufficient technical justification for each difference/deviation. In particular, the proposed license amendment does not provide a complete and accurate mapping to the EAL revision 7 scheme, explanations for the changes to the as built/as modified plant, changes to instruments and values, or substantial additions or deletions of text in the EAL bases.
The LAR appears to lack sufficient documentation to confirm that all the applicable calculations supporting adoption of NEI 99-01, Revision 7, are the same as those approved for Revision 6, or to provide the applicable revised calculations.
The LAR provides a mark-up of proposed changes but does not include a clean and complete proposed version of the EAL schemes including the front matter for each of the sites.

Conclusion
- The NRC staff is not making any regulatory decision at todays meeting.
- Once the needed supplemental information is received, the NRC staff will make a regulatory decision regarding acceptance of the LAR in writing in a timely manner.
