EXECUTIVE SUMMARY

Exelon Generation Co., LLC

Oyster Creek Nuclear Generating Station NRC Inspection Report No. 05000219/2019001 An announced quarterly inspection was completed at Oyster Creek Nuclear Generating Station (Oyster Creek) on March 31, 2019. On-site inspections and in-office reviews of information supplied by Exelon were performed during the inspection period from January 1 to March 31.

The inspection included a review of organization and management at the site; safety reviews, design changes and modifications; self-assessments, audits and corrective actions; and decommissioning performance and surveillance.

The inspection consisted of observations by the inspector, interviews with Exelon personnel, a review of procedures and records, and plant walk-downs. The U.S. Nuclear Regulatory Commissions (NRC's) 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 On September 25, 2018, Oyster Creek certified the permanent removal of fuel from the reactor vessel (Agencywide Documents and Access Management System (ADAMS)

Accession No. ML18268A258). This met the requirements of 10 Code of Federal Regulations (CFR) 50.82(a)(1)(i) and 50.82(a)(1)(ii). On October 1, 2018, the NRC notified Oyster Creek that the Operating Reactor Assessment Program had ceased and that implementation of the Decommissioning Power Reactor Inspection Program would begin on October 1, 2018 (ADAMS Accession No. ML18274A221). Oyster Creek is currently in the Post Operation Transition Phase of decommissioning as described in IMC 2561.

2.0 Post Operation Transition Phase Performance and Status Review

a. Inspection Scope

[Inspection Procedures 36801, 37801, 40801, 71801]

The inspector performed on-site inspections on January 28-30, March 7, and March 26.

In-office reviews of information supplied by Exelon were also performed during the inspection period. The inspection consisted of observations by the inspector, interviews with Exelon personnel, a review of procedures and records, and plant walk-downs.

The inspector reviewed procedures and processes to evaluate Exelons ability to resolve employee safety concerns, disseminate safety information and effectively resolve identified problems. The inspector reviewed Exelons decommissioning activities to verify they were performed in a manner consistent with the Post-Shutdown Decommissioning Activities Report (PSDAR). The inspector observed licensee meetings that planned, reviewed, assessed and scheduled the conduct of facility decommissioning. The inspector performed plant tours to assess field conditions and decommissioning abandonment activities.

The inspector conducted document reviews and interviews with plant personnel to verify Exelon procedures and processes followed the regulations and guidance associated with 10 CFR 50.59. The inspector reviewed the modifications to the radwaste system to allow for overboard discharge of radioactive liquid while ensuring compliance with radioactive effluent discharge regulations. The inspector reviewed the engineering change package, condition reports, and plant drawings to determine if the modification would meet the requirements of the technical specifications, Offsite Dose Calculation Manual (ODCM),

and plant procedures. The inspector also reviewed discharge release permits and meeting minutes for the last Safety Review Committee meeting.

The inspector reviewed documents and interviewed Oyster Creek personnel to verify Exelon management performed audits and self-assessments, and ensured issues were identified and corrected in accordance with the sites corrective action program (CAP).

The inspector reviewed a representative selection of CAP documents 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 The inspector verified that management oversight was adequate for the post-operation transition phase of decommissioning and that no significant changes had been made to the Oyster Creek decommissioning organization since the previous inspection. The inspector determined that the employee concerns program was appropriately implemented. The inspector noted that site decommissioning activities were in accordance with the PSDAR.

The inspector determined that 10 CFR 50.59 screenings and evaluations are being performed and that Exelon has trained and qualified individuals to perform the evaluations. The inspector determined that changes under 10 CFR 50.59 did not require prior NRC approval and safety reviews were performed for design changes and modifications. The inspector verified the overboard discharge modification was complete and reviewed the release permits to ensure compliance with the Technical Specification and ODCM. The inspector also verified that the engineering change was performed in accordance with site procedures and safety reviews had been performed adequately.

The inspector determined that issues were being identified and entered into the CAP 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 On April 4, 2019, the inspector presented the inspection results to Mr. Jeff Dostal, Plant Manager, and other members of the Exelon staff who acknowledged the inspection results. The inspectors verified that no proprietary information was retained by the inspectors or documented in this report.
