.. Southern Nuclear January 15, 2025 Docket Nos.: 50-424 50-425 U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D. C. 20555-0001 Regulatory Affairs Vogtle Electric Generating Plant - Units 1 and 2 License Renewal Commitment Item 12 Ladies and Gentlemen:
3535 Colonnade Parkway Birmingham, AL 35243 205 992 5000 NL-24-0365 Commitment Item No. 12 of NUREG-1920, Safety Evaluation Report Related to the License Renewal of the Alvin E. Vogtle Electric Generating Plant (VEGP), Units 1 and 2, requires the submission of an inspection plan to the staff for review and approval for the Nickel Alloy Management Program for non-reactor vessel closure head (non-RVCH) penetration locations at least 24 months prior to entering the periods of extended operation for the VEGP units. The period of extended operation for VEGP, Unit 1 begins on January 16, 2027, and February 9, 2029, for Unit 2. Since establishing this commitment, the industry and Nuclear Regulatory Commission (NRC) have adopted a strategy to proceed with a generic approach through the consensus process provided by the American Society of Mechanical Engineers (ASME) Code Section XI. Thus, the nickel-based alloy inspection program, for non-RVCH penetration locations, is based on industry consensus prescribed in ASME Code Cases N-722-1 and N-770-5 as mandated and conditioned in 10 CFR 50.55a. SNC will perform update to these programs as mandated by 10 CFR 50.55a.
This Nickel Alloy pressure boundary inspection program has been fully incorporated into the VEGP lnservice Inspection program, is being conducted accordingly, and has undergone periodic review by Region II inspectors. Southern Nuclear Operating Company (SNC) believes that there is not a need for additional staff review and approval of the technical details and/or basis for the VEGP Units 1 and 2 plant specific inspection plans because the technical basis for the scope, periodicity, nondestructive examination requirements, and acceptance criteria are all now generically approved and mandated via rulemaking.
SNC believes that this notification effectively fulfills the intent of commitment item 12 contained in NUREG-1920, which was established prior to staff rulemaking on the generic ASME Code Case requirements.
This letter contains no new regulatory commitments. If you have any questions, please contact Ryan Joyce at (205) 992-6468.
