SUBJECT:
DRESDEN NUCLEAR POWER STATION, UNITS 2 AND 3 - REGULATORY AUDIT IN SUPPORT OF LICENSE AMENDMENT REQUESTS TO ADOPT TSTF-505, REVISION 2, PROVIDE RISK-INFORMED EXTENDED COMPLETION TIMES - RITSTF INITIATIVE 4B; TSTF-591, REVISION 0, REVISE RISK INFORMED COMPLETION TIME (RICT) PROGRAM; AND 10 CFR 50.69, RISK-INFORMED CATEGORIZATION AND TREATMENT OF STRUCTURES, SYSTEMS AND COMPONENTS FOR NUCLEAR POWER REACTORS (EPID L-2024-LLA-0061 AND EPID L-2024-LLA-0069)
Dear David Rhoades:
By letters dated May 8, 2024, and May 28, 2024, Constellation Energy Generation, LLC (CEG, the licensee) submitted license amendment requests (LARs) to amend the licenses for Dresden Nuclear Power Station, Units 2 and 3, Renewed Facility Operating License Nos. DPR-19 and DPR-25, respectively. The proposed LARs would adopt Technical Specifications Task Force Traveler 505, Revision 2, Provide Risk-informed Extended Completion Times - RITSTF Initiative 4b (TSTF-505); TSTF-591, Revision 0, Revise Risk Informed Completion Time (RICT) Program; and the provisions of Title 10 of the Code of Federal Regulations (10 CFR),
Section 50.69, Risk-informed categorization and treatment of structures, systems and components for nuclear power reactors.
To support its review of the above LARs, the U.S. Nuclear Regulatory Commission (NRC) staff conducted a virtual regulatory audit from October 23, 2024, through February 19, 2025. During the regulatory audit, the NRC staff reviewed documents and held discussions with members of CEG and its representatives. The regulatory audit summary is enclosed with this letter.
D. Rhoades If you have any questions, please contact me by telephone at 301-415-1421 or by email to Surinder.Arora@nrc.gov.
Sincerely,
/RA/

Enclosure REGULATORY AUDIT
SUMMARY
BY THE OFFICE OF NUCLEAR REACTOR REGULATION TO SUPPORT THE REVIEW OF LICENSE AMENDMENT REQUEST TO ADOPT REQUIREMENTS OF TSTF-505, TSTF-591, AND 10 CFR 50.69 CONSTELLATION ENERGY GENERATION, LLC DRESDEN NUCLEAR POWER STATION, UNIT 2 AND 3 DOCKET NOS. 50-237 AND 50-249
1.0 BACKGROUND
By letters dated May 8, 2024, and May 28, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession Nos. ML24129A135 and ML24149A261),
Constellation Energy Generation, LLC (CEG, the licensee) submitted license amendment requests (LARs) to amend the licenses for Dresden Nuclear Power Station, Units 2 and 3, Renewed Facility Operating License Nos. DPR-19 and DPR-25, respectively. The proposed LARs would adopt Technical Specifications Task Force Traveler 505, Revision 2, Provide Risk-informed Extended Completion Times - RITSTF Initiative 4b (TSTF-505); TSTF-591, Revision 0, Revise Risk Informed Completion Time (RICT) Program; and the provisions of Title 10 of the Code of Federal Regulations (10 CFR), Section 50.69, Risk-informed categorization and treatment of structures, systems and components for nuclear power reactors.
Information that the U.S. Nuclear Regulatory Commission (NRC) staff relies upon to make the safety determination must be submitted on the docket. However, the NRC staff may review supporting information retained as records under Title 10 of the Code of Federal Regulations (10 CFR) 50.71 and/or 10 CFR 54.37, which, although not required to be submitted as part of the licensing actions, would help the NRC staff better understand the licensees submitted information. To support its review of the LAR, the NRC staff issued a regulatory audit plan (ML24204A186) on July 24, 2024. The purpose of the audit is to review the documentation related to the subject of its applications (e.g., calculations and reports) that were not submitted on the licensees docket, to acquire additional understanding about the amendment request, and to determine whether additional information is needed to be docketed to complete the NRC staffs safety evaluations.
2.0 AUDIT ACTIVITIES The NRC audit team consisted of NRC staff and contract support from the Pacific Northwest National Laboratory (PNNL). Attachment 1 of this audit summary lists the individuals that took part in or attended the audit meetings. The NRC audit team conducted a virtual regulatory audit from October 23, 2024, through February 19, 2025. Throughout the audit period, the NRC audit team used an internet-based portal provided by the licensee to review primarily non-docketed information related to the applications. To support discussions, the NRC staff provided audit questions with items for CEG to provide responses. CEG posted its responses to the staffs questions to the online portal. The NRC staff held multiple discussions with the CEG staff via Microsoft Teams on October 23, 2024; December 3-5, 2024; February 14, 2025; and February 19, 2025. There was some additional information uploaded to the online portal by the licensee after the meeting on February 19, 2025, that the staff reviewed to conclude the audit.
3.0 RESULTS OF THE AUDIT On March 19, 2025, the licensee provided a supplement (ML24354A255) to its application. The NRC staff will review the licensees supplement to assess if any additional information is needed to complete its safety evaluation of the LAR. One request for additional information was issued to the licensee on March 25, 2025 (ML25080A153).
