EXECUTIVE SUMMARY
Exelon Generation Company, LLC
Peach Bottom Atomic Power Station Unit 1 (Unit 1)
NRC Inspection Report No. 05000171/2019001
An announced safety inspection was conducted on May 1-2, 2019, at Unit 1. The inspectors reviewed activities related to the decommissioning performance and status, management oversight, corrective action program (CAP), and site radiological programs. The inspection consisted of interviews with Exelon personnel, a review of procedures and records, and plant walk-downs. The NRCs program for overseeing the safe operation of a shut-down nuclear power reactor is described in Inspection Manual Chapter (IMC) 2561, Decommissioning Power Reactor Inspection Program. Based on the results of this inspection, no findings of safety significance were identified.
REPORT DETAILS
1.0 Background
Unit 1 was a high temperature gas-cooled demonstration power reactor that operated from February 1966 until October 31, 1974, and has been permanently shut down and in SAFSTOR since that time. All fuel has been removed from the reactor and shipped to an offsite facility. The spent fuel pool has been drained and decontaminated and radioactive liquids have been removed. Intrusion water that collects in the reactor building sump is periodically pumped out of the sump and transferred to the common radwaste building for Peach Bottom Units 2 and 3 for processing.
The NRC's program for overseeing the safe operation of a shut-down nuclear power reactor is described in IMC 2561.
2.0 SAFSTOR Performance and Status Review
a. Inspection Scope
(Inspection Procedures (IPs) 36801, 37801, 40801, 71801, 83750, 84750, 86750)
A routine announced safety inspection was conducted on May 1-2, 2019, at Unit 1. The inspection consisted of plant walkdowns, interviews with Exelon personnel, and a review of procedures and records. 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 Unit 1 facility. Specifically, the inspectors reviewed the decommissioning management and staff organization and Exelons implementation of Unit 1 programs for the SAFSTOR phase of decommissioning. The inspectors also conducted a walk-down to assess the material condition of the Unit 1 buildings.
The inspectors reviewed the results of the Exelon Unit 1 Exclusion Area Inspection semi-annual surveillance test to ensure exclusion area barriers, water intrusion, and effluent release limits are as specified in the TS. The inspectors reviewed the occupational dose records, radwaste records, and environmental monitoring reports to determine the effectiveness of site radiological programs.
The inspectors reviewed documents and interviewed personnel to verify issues were
identified and corrected in accordance with the sites CAP. The inspectors reviewed
assignment reports associated with Unit 1 to determine if a sufficiently low threshold for
problem identification existed, follow-up evaluations were of sufficient quality, and
Exelon assigned timely and appropriate prioritization for issue resolution commensurate
with the significance of the issue.
b. Observations and Findings
The inspectors verified that management oversight was adequate for the SAFSTOR phase of decommissioning and that no significant changes had been made to the Unit 1 SAFSTOR organization since the previous inspection. The inspectors confirmed that no design changes or plant modifications were made since the previous inspection.
The inspectors confirmed surveillances were performed as required by the TS. The inspectors determined site radiological programs were effective in limiting exposure and intrusion water was transferred to Units 2 and 3 in accordance with plant procedures.
The inspectors verified that the annual radiological effluent report demonstrated that calculated doses were below regulatory dose criteria of 10 CFR 50, Appendix I.
The inspectors determined that issues were being identified and entered into the CAP in a timely manner and the issues were effectively screened, prioritized and evaluated commensurate with their safety significance.
c. Conclusions
Based on the results of this inspection, no findings of safety significance were identified.
3.0
Exit Meeting Summary
On May 2, 2018, the inspectors presented the inspection results to Pat Navin, Site Vice President, and other members of Exelons staff. The inspectors confirmed that no copies of proprietary information were used during this inspection and none were removed from the site.
