PEACH BOTTOM ATOMIC POWER STATION, UNIT 1 - REGULATORY AUDIT
SUMMARY
REGARDING PROPOSED ALTERNATIVE SCHEDULE TO COMPLETE DECOMMISSIONING BEYOND 60 YEARS (EPID L-2023-LLN-0004)
Dear David P. Helker By letter dated October 20, 2023 (Agencywide Documents Access and Management System Accession No. ML23293A305), Constellation Energy Generation, LLC (Constellation, the licensee) submitted a request for Peach Bottom Atomic Power Station, Unit 1 (Peach Bottom Unit 1). The proposed request would allow the completion of decommissioning for Peach Bottom Unit 1 beyond 60 years of permanent cessation of operations.
To support its review of the request, the U.S. Nuclear Regulatory Commission (NRC) staff conducted a regulatory audit that was conducted on April 11, 2024, at the Peach Bottom Atomic Power Station in Delta, PA. The NRC staff reviewed documents and held discussions with members of Constellation. A summary of the regulatory audit, schedule of activities, list of participants, and list of documents are enclosed.
Sincerely, Tanya E. Hood, Project Manager Reactor Decommissioning Branch Division of Decommissioning, Uranium Recovery and Waste Programs Office of Nuclear Material Safety and Safeguards Docket No. 50-171

REGULATORY AUDIT
SUMMARY
DECOMMISSIONING BEYOND 60 YEARS
CONSTELLATION ENERGY GENERATION, LLC
PEACH BOTTOM ATOMIC POWER STATION, UNIT 1
DOCKET NO. 50-171
1.0 BACKGROUND
By letter dated October 20, 2023 (Agencywide Documents Access and Management System Accession No. ML23293A305), Constellation Energy Generation, LLC (the licensee) submitted a request for Peach Bottom Atomic Power Station, Unit 1 (Peach Bottom Unit 1). The proposed request would allow the completion of decommissioning for Peach Bottom Unit 1 beyond 60 years of permanent cessation of operations.
An audit plan was issued by the U.S. Nuclear Regulatory Commission (NRC) staff by email on March 28, 2024 (ML24088A318). The scope of the audit was to gain a more detailed understanding of the licensees processes and procedures to support the NRC staffs licensing decision regarding the request and to identify any information that may require docketing to support the NRC staffs licensing basis.
An audit was determined to be the most efficient approach toward a timely resolution of questions associated with this request. The audit was performed consistent with NRC Office of Nuclear Reactor Regulation Office Instruction LIC-111, Revision 1, Regulatory Audits, dated October 31, 2019 (ML19226A274). A regulatory audit is a planned license or regulation-related activity that includes the examination and evaluation of primarily non-docketed information.
Information that the NRC staff relies upon to make the safety determination must be submitted on the docket. This approach is expected to minimize the potential for multiple rounds of requests for additional information (RAIs) and eliminate questions that would no longer be necessary to make a safety determination.
2.0 AUDIT DATES AND LOCATION
The regulatory audit was conducted on April 11, 2024, at the Peach Bottom Atomic Power Station in Delta, PA. The NRC staff reviewed documents and held technical discussions of audit questions with members of the licensee according to the audit plan.
Enclosure 1 3.0 AUDIT ACTIVITIES
The NRC audit team held a full one-day audit with the licensees staff and contractors that consisted of touring the site which allowed the NRC staff to examine and evaluate information with the intent to gain understanding, verify information, and identify information that will require docketing to support a regulatory decision. The licensee established an online portal in advance of the meeting which allowed the NRC staff to access documents remotely via the internet. This action allowed the NRC staff the opportunity to participate in detailed technical discussions on various topics with the licensee. The detailed discussions were also aided by information needs identified by the NRC staff in the audit plan, along with the licensees presentations and prepared responses to audit questions.
The NRC staff identified information it needed on the docket to support its review. Enclosure 2 provides the schedule of activities during the audit. Enclosure 3 lists audit participants on the NRC audit team. Enclosure 4 lists the documents reviewed during the audit. There were no deviations from the finalized audit plan. No regulatory decisions were made during the audit.
4.0 RESULTS OF THE AUDIT
An audit exit meeting was held at the end of the day, the NRC staff reviewed the proposed resolution to the audit questions with the licensee and reached a consensus regarding the proposed responses to the questions. Based on insights from the audit, the licensee indicated that they could provide a supplement to the request that would address the majority of audit questions asked by the NRC staff. By letter dated May 13, 2024 (ML24134A179), the licensee provided a supplement to the requested licensing action.
The NRC staff communicated to the licensee that upon review of the supplement the NRC staff would determine the need for an RAI. The information submitted in support of the request is under final review, and any additional information needed to support the review will be formally requested by the NRC staff using the RAI process in accordance with the Office of Nuclear Reactor Regulation Office Instruction LIC-101, Revision 6, License Amendment Review Procedures (ML19248C539).
