PERRY NUCLEAR POWER PLANT, UNIT NO. 1 - CORRECTION OF THE ISSUANCE DATE OF THE SAFETY EVALUATION FOR THE LICENSE RENEWAL APPLICATION REVIEW ON THE TECHNICAL SPECIFICATION PAGE (EPID NO. L-2023-RNW-0002)
Dear Mr. Brown:
By letter dated July 3, 2023 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML23184A081), Energy Harbor Nuclear Corporation submitted to the U.S. Nuclear Regulatory Commission (NRC) an application for license renewal of Facility Operating License No. NFP-58 for Perry Nuclear Power Plant (Perry), Unit No. 1, pursuant to Title 10 of the Code of Federal Regulations Part 54, Requirements for Renewal of Operating Licenses for Nuclear Power Plants. Effective March 1, 2024, the facility operating license for Perry was transferred from Energy Harbor Nuclear Generation LLC (owner) and Energy Harbor Nuclear Corporation (operator) to Energy Harbor Nuclear Generation (owner) and Vistra Operations Company LLC (operator) (package, ML24057A092). Upon completion of this license transfer, Vistra Operations Company, LLC (Vistra or the applicant) assumed responsibility for all licensing actions under NRC review at the time of the transfer and requested that the NRC continue its review of these actions (ML24054A498). Energy Harbor Nuclear Corporation and Vistra further supplemented the license renewal application by letters dated June 27, 2024 (ML24180A010), July 24, 2024 (ML24206A150), August 7, 2024 (ML24220A270), September 5, 2024 (ML24249A123), October 21, 2024 (ML24295A352), November 7, 2024 (ML24312A368),

The NRC staff completed its safety evaluation (SE) of the license renewal of Facility Operating License No. NFP-58 for Perry, Unit 1 on May 29, 2025 (package, ML25231A205), and on July 7, 2025, the NRC staff issued the renewed license (ML25160A130). On August 19, 2025, the staff issued Revision 1, of the SE report (ML25231A221) which impacted the License Renewal Conditions, section, on page 5 of the revised Technical Specifications (TS). When the SE report was issued on May 29, 2025, the revised TS page 5 included the date of May 2025. With the issuance of Revision 1 of the SE, the NRC staff has revised the date to August 2025 to reflect the change. The corrected Perry TS Page 5 is enclosed. Please remove the current page September 19, 2025
T. Brown 5 and insert the corrected page 5. The other pages issued as part of the TS were not affected by this change.
