SUBJECT:
CONSTELLATION ENERGY GENERATION, LLC, PEACH BOTTOM ATOMIC POWER STATION UNIT 1 - NRC INSPECTION REPORT NO.
Dear David Rhoades:
On December 5, 2024, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection under Inspection Manual Chapter 2561, Decommissioning Power Reactor Inspection Program, at the permanently shutdown Peach Bottom Atomic Power Station Unit 1. The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and the conditions of your license. The inspection consisted of observations by the inspectors, interviews with site personnel, a review of procedures and records, and plant walk downs. The results of the inspection were discussed with Ryan Stiltner, Plant Manager and other members of your staff on December 5, 2024, and are described in the enclosed report.
Within the scope of this inspection, no violations of more than minor safety significance were identified.
In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRCs Rules of Practice, a copy of this letter, its enclosure(s), and your response, if any, will be made available electronically for public inspection in the NRC Public Document Room or from the NRC Agencywide Document and Management System (ADAMS), accessible from the NRC website at http://www.nrc.gov/reading-rm/adams.html. To the extent possible, your response, if any, should not include any personal privacy, proprietary, or safeguards information so that it can be made available to the Public without redaction.

EXECUTIVE SUMMARY
Constellation Energy Generation, LLC
Peach Bottom Atomic Power Station Unit 1 NRC Inspection Report No. 05000171/2024001
An announced routine SAFSTOR inspection was completed on December 5, 2024. An on-site inspection was performed on December 3, 2024. The inspection included a review of activities related to the safe storage of radioactive material, including surveillance, engineering, maintenance, plant support activities, management oversight, and corrective action program (CAP) implementation. The inspection consisted of observations by the inspectors, interviews with site personnel, a review of procedures and records, and plant walk-downs. The U.S.
Nuclear Regulatory Commissions (NRCs) program for overseeing the safe storage of a shutdown nuclear power reactor is described in Inspection Manual Chapter (IMC) 2561,
Decommissioning Power Reactor Inspection Program.
Based on the results of this inspection, no violations of more than minor safety significance were identified.
REPORT DETAILS
1.0 Background
Peach Bottom Unit 1 was a high temperature gas-cooled demonstration power reactor that operated from February 1966 until October 31, 1974. It was permanently shut down and has been in safe storage (SAFSTOR) since that time. All fuel from Unit 1 has been removed from the reactor and shipped to an offsite facility. The spent fuel pool has been drained, decontaminated, and radioactive liquids have been removed. Intrusion water that occasionally collects in the reactor containment sump is periodically pumped out of the sump and transferred to the common radwaste building used for Peach Bottom Units 2 and 3 for processing.
The NRCs program for overseeing the safe storage and decommissioning of a permanently shut-down nuclear power reactor is described in IMC 2561.
2.0 SAFSTOR Performance and Status Review
a. Inspection Scope
(Inspection Procedures 37801, 40801, 60801, 64704, 71801, 83750, 84750, 86750)
A routine announced safety inspection was conducted from December 2-5, 2024. The inspection consisted of observations by the inspectors, interviews with Constellation personnel, a review of procedures and records, and plant walk downs. The inspectors reviewed the SAFSTOR program as outlined in the Updated Final Safety Analysis Report (UFSAR), Technical Specifications (TS), and procedure DC-PB-800, Unit 1 Process Control Program, to assess the adequacy of management oversight for the Unit 1 facility. Specifically, the inspectors reviewed the decommissioning management and staff organization and Constellations implementation of Unit 1 programs for the SAFSTOR phase of decommissioning. The inspectors also conducted plant walk-downs of exclusion areas to assess the material condition of the Unit 1 buildings (reactor building, containment building, and spent fuel pool building).
The inspectors reviewed the results of the Constellation Unit 1 Exclusion Area Inspection semi-annual surveillance tests to ensure exclusion area barriers, radiological conditions, water intrusion, and effluent release limits are as specified in the TS. Additionally, the inspectors reviewed the program for structural monitoring inspections at Unit 1, by observing Constellations periodic routine surveillance entry inspection.
The inspectors reviewed activities, components, and documentation associated with the following SAFSTOR programs: decommissioning organization, staffing, and cost controls; safety reviews and modifications; fire protection; maintenance, surveillance, and decommissioning trust fund expenditures.
The inspectors evaluated whether the following programs that remain associated with programs for Units 2 and 3 were being adequately applied and administered for Unit 1: occupational radiation exposure, Radioactive Effluent Technical Specifications (RETS), the site Radiological Environmental Monitoring Program (REMP), and the processing and transportation of radioactive waste.
b. Observations and Findings
The inspectors confirmed that the SAFSTOR program was being effectively implemented. The inspectors checked that the maintenance and surveillance program for systems and components had been conducted in accordance with the technical specification requirements and established procedures. The inspectors also observed that no design changes or plant modifications were made since the previous inspection.
The inspectors reviewed any modifications to the site, temporary or permanent, since the last SAFSTOR inspection. The inspectors reviewed information relevant to the status of the decommissioning trust fund, its expenditures, and the work performed at Unit 1 during the inspection period, with no concerns identified.
The Constellation staff performed walkdowns of all accessible locations of the Unit 1 exclusion area. The entrances to containment were barricaded (as required by TS) with a locked fence and posted as a Radiologically Controlled Area (RCA). All entrants were briefed on radiological conditions, signed-onto the appropriate radiological work permit, and escorted by radiological protection staff.
The inspectors determined that the RETS and REMP programs met the requirements of the ODCM and included contributions from Unit 1. The Annual Radiological Effluent Release Report (ARERR) and Annual Radiological Environmental Operating Report (AREOR) demonstrated that all calculated doses were below regulatory limits.
Findings or issues identified in audits, plant equipment operator rounds, and staff observations were entered into the CAP at the appropriate threshold. Site staff effectively addressed the issues identified, implemented corrective actions, and tracked them to closure. The condition reports and corrective actions reviewed during the inspection were prioritized and evaluated commensurate with their safety significance.
c. Conclusions
Based on the results of this inspection, no violations of more than minor safety significance were identified.
