EXECUTIVE SUMMARY

Holtec Decommissioning International, LLC

Oyster Creek Nuclear Generating Station NRC Inspection Report No. 05000219/2020002 An announced decommissioning inspection was completed at Oyster Creek Nuclear Generating Station (Oyster Creek) on June 30, 2020. An on-site inspection was performed on June 17, 2020. Additional inspection activities (in-office reviews) were conducted remotely during the inspection period as a consequence of the COVID-19 public health emergency (PHE). The inspection included a review of safety reviews, design changes, and modifications; self-assessments, audits, and corrective actions; decommissioning performance and status reviews; occupational radiation exposure; and inspection of remedial and final surveys.

The inspection consisted of observations by the inspector, interviews with Oyster Creek 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 violations 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 Document Access and 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). On July 1, 2019, an amended license was issued transferring the license from Exelon Generation Co., LLC to Holtec Decommissioning International, LLC (ADAMS Accession No. ML19164A157).

Oyster Creek is currently in the Actively Decommissioning, Fuel in the Spent Fuel Pool phase of decommissioning as described in IMC 2561.

2.0 Active Decommissioning Performance and Status Review 2.1 Inspection Procedure (IP) 37801, 40801, 71801, 83750, 83801

a. Inspection Scope

In-office reviews of information supplied by Oyster Creek were performed during the inspection period. The inspector performed an on-site inspection on June 17, 2020.

Additional inspection activities were conducted remotely during the inspection period as a consequence of the COVID-19 PHE. The inspection consisted of observations by the inspector, interviews with Oyster Creek personnel, a review of procedures and records, and plant walk-downs.

The inspector conducted document reviews and interviews with plant personnel to determine if procedures and processes were in accordance with regulations and guidance associated with 10 CFR 50.59 Changes, tests, and experiments. The inspector reviewed the 10 CFR 50.59 screenings for three onsite activities including an editorial change to an on-site low-level radioactive waste facility configuration, de-vitalization of various rooms throughout the plant, and a refuel bridge monorail modification. The inspector also reviewed the screening criteria to determine if evaluations were required, in accordance with 10 CFR 50.59 for the changes and modifications.

The inspector reviewed documents and interviewed site personnel to determine if HDI 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 HDI assigned timely and appropriate prioritization for issue resolution commensurate with the significance of the issue.

The inspector reviewed the status of activities related to the site decommissioning to determine if activities were in accordance with licensed requirements. The inspector observed decommissioning activities associated with the preparation, segmentation and storage of portions of the steam dryer and steam separator. The inspector interviewed workers and reviewed work packages, plans, and procedures for the activities observed.

The inspector reviewed the decommissioning schedule to determine if the schedule was consistent with the post shutdown decommissioning activities report (PSDAR).

The inspector observed radiation protection technician job coverage of maintenance activities, toured the radiologically controlled areas, and reviewed radiological surveys and as low as reasonably achievable (ALARA) plans for ongoing projects to verify that radiation work activities were pre-planned effectively to limit worker exposure. The inspector examined radiological postings, locked high radiation doors, and general housekeeping.

The inspector reviewed Oyster Creeks Historical Site Assessment to determine if the radiological conditions during the operating history at Oyster Creek were accurately represented. The inspector conducted site walkdowns and reviewed radiological surveys to confirm conclusions made throughout the document.

b. Observations and Findings

The inspector determined that the 10 CFR 50.59 screenings were performed by trained and qualified individuals. 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 that the licensee correctly determined that 10 CFR 50.59 evaluations were not required for issues including: an editorial change to the on-site low-level radioactive waste facility configuration, de-vitalization of various rooms throughout the plant, and modification of the refuel bridge monorail.

Specifically, the changes to the plant did not result in any changes that adversely affected the design function of any system, structure, or component described in the Decommissioning Safety Analysis Report.

The inspector determined that issues had been identified and entered into the CAP in a timely manner and the issues were effectively screened, prioritized and evaluated commensurate with their safety significance. The inspector verified that audits and self-assessments were performed by qualified individuals independent of the organization being audited, and management reviewed the audits and associated corrective actions.

The inspector noted the next main decommissioning activities during this inspection period include the reactor vessel internals segmentation project. The inspector determined the activities were performed safely and in accordance with work plans and plant procedures. The inspector verified the activities and schedule were consistent with the September 28, 2018, notification by HDI revising the PSDAR for Oyster Creek.

The inspector verified that radiation protection staff effectively controlled work activities and survey records were clear and complete. The inspector verified that ALARA plans were performed as needed and were effective in limiting worker exposure and occupational dose was acceptable for the scope of the radiological activities performed.

The inspector verified that the Historical Site Assessment adequately defined the current and historical radiological conditions of the site.

c. Conclusions

Based on the results of this inspection, no violations of safety significance were identified.

3.0 Exit Meeting On July 13, 2020, the inspector presented the inspection results to Mr. Jeffrey Dostal, HDI Oyster Creek Site Vice President, and other members of the Oyster Creek staff who acknowledged the inspection results. The inspector verified that no proprietary information was retained by the inspector or documented in this report.
