EXECUTIVE SUMMARY Palisades Nuclear Plant NRC Inspection Report Nos. 05000255/2023003(DRSS)

The Palisades Nuclear Plant is permanently shut-down and defueled power reactor. This periodic safety inspection reviewed licensed activities associated with decommissioning performance; occupational radiation exposure; radiological surveys; and radioactive waste treatment, effluent, and environmental monitoring.

Decommissioning Performance and Status Review

The inspectors reviewed documentation related to the decommissioning trust fund and met with the plant staff to discuss if the funds were used in accordance with NRC requirements.

The inspectors identified one unresolved item involving decommissioning trust funds used to pay for non-decommissioning activities.

Occupational Radiation Exposure

Adequate protection of worker health and safety from exposure to radiation and radioactive material was provided. Decommissioning activities were executed in general alignment with planning documents and as provided in RWPs and ALARA reviews. Radiation surveys were performed adequately to identify the hazards present. Command and control of radiologically significant activities was executed in a manner that was safe and achieved the desired result.

Radioactive Waste Treatment, and Effluent and Environmental Monitoring

The effluent flow paths and environmental monitoring systems reviewed aligned with descriptions in the Offsite Dose Calculation Manual and were functional. The effluent monitors reviewed were functional, calibrated, and alarm set points conservatively set to meet regulatory requirements. Changes to the effluent and environmental monitoring program were consistent with regulatory requirements.

Report Details Summary of Plant Activities During this inspection period, the licensee continued activities associated with Period 2 of the Post Shutdown Decommissioning Activities Report (PSDAR). No major decommissioning activities occurred during the inspection period.

1.0 Decommissioning Performance and Status Review (IP 71801)

1.1 Inspection Scope The inspectors reviewed documents, and interviewed plant personnel to assess the licensees performance in the following areas:

Changes to the decommissioning schedule or costs were made consistent with the requirements in 10 CFR 50.82(a)(7).

The inspectors verified that when issues were identified, licensee personnel appropriately documented the issues in the Corrective Action Program (CAP).

1.2 Observations and Findings The inspectors reviewed documentation related to the use of the decommissioning trust fund (DTF). Specifically, there were seven instances totally just over $53,000 in which the licensee used decommissioning trust funds to pay for non-decommissioning activities. The licensee entered this matter into its corrective action program and repaid the money back to the DTF with interest. The licensee stated that the unauthorized reimbursements from the DTF were the result of inadvertent oversights and/or inattention to detail; that is, they were the result of human performance errors, not process-related or programmatic issues. As a result, the licensee instituted several process revisions addressing purchase order coding modifications and training to ensure such unauthorized reimbursements do not occur in the future. This is considered an unresolved item (URI 05000255/2023003-01) pending further NRC review to ascertain if a violation of NRC requirements occurred, and if so, the appropriate enforcement action.

1.3 Conclusions The inspectors identified one unresolved item involving decommissioning trust funds used to pay for non-decommissioning activities.

2.0 Occupational Radiation Exposure at Permanently Shutdown Reactors (IP 83750)

2.1 Inspection Scope The inspectors performed walkdowns, reviewed documents, and interviewed plant personnel to assess the licensees performance in the following areas:

Changes made to organization, personnel, facilities, instrumentation, equipment, and programs that impact occupational radiation protection;

Training and qualifications of members of the radiation protection organization;

Radiological hazards and worker protection in work activities;

Planning identified appropriate dose reduction techniques, defined reasonable dose goals, and radiation protection hold points;

Radiological controls, postings, and material conditions inside the radiological control area;

Planned special exposures;

External exposure dosimetry; Internal exposure dosimetry; Special dosimetric situations;

Engineering controls, respiratory protection program, and dose assessments;

Contamination monitoring including release of radioactive materials from controlled areas;

Accuracy and functionality of radiation monitoring instruments;

Area radiation monitors and continuous air monitors were appropriately positioned;

Temporary ventilation systems were correctly configured; and

The characterization of the radiation type and energies were appropriate to the surveys and work practices.

The inspectors verified that when issues were identified, licensee personnel appropriately documented the issues in the CAP.

2.2 Observations and Findings The inspectors performed walkdowns of the plant on August 22-23, 2023. There were no changes to the licensees organization that impacted the radiation protection program.

The inspectors found that adequate measures were established in the plant building to reasonably prevent the creation of airborne hazards; control the spread of contamination; and to reduce external dose. A review of selected radiological surveys did not identify any unusual radiological conditions. During tours of the radiation area and high radiation area, the inspectors observed that general housekeeping had been maintained, radiological postings and barriers were found to be in good condition and properly located, and all personnel were appropriately monitored through the inspection period.

No findings were identified.

2.3 Conclusions Adequate protection of worker health and safety from exposure to radiation and radioactive material was provided. Decommissioning activities were executed in general alignment with planning documents and as provided in RWPs and ALARA reviews.

Radiation surveys were performed adequately to identify the hazards present. Command and control of radiologically significant activities was executed in a manner that was safe and achieved the desired result.

3.0 Radioactive Waste Treatment, and Effluent and Environmental Monitoring (IP 84750)

3.1 Inspection Scope The inspectors performed walkdowns, reviewed documents, and interviewed plant personnel to assess the licensees performance in the following areas:

Changes made to the Offsite Dose Calculations Manual (ODCM) or liquid, gaseous, and solid radwaste system design and operation were within the licensing basis and regulations;

Effluent monitoring ventilation and discharge system configurations, flow paths, and operations were consistent with the licensing basis and procedures;

Effluent monitors were calibrated;

Radioactive liquid and gaseous waste discharge permits projected doses to members of the public that were based on representative samples in the discharge pathway and were within 10 CFR Part 50, Appendix I, and Technical Specification limits;

The annual effluent release report was submitted as required, and any anomalous results, unexpected trends, or abnormal releases were identified and entered into the Corrective Action Program;

Environmental monitoring equipment was properly located, calibrated and maintained, and environmental samples were adequately collected;

Whether the Groundwater Protection Initiative program was implemented as intended;

Whether potential leakage or spills were appropriately added to records as required by 10 CFR 50.75(g);

The licensees annual radiological environmental monitoring report was submitted as required, and any anomalous results, unexpected trends, or abnormal environmental impacts were identified and entered into the Corrective Action Program;

Meteorological instruments were operable, calibrated, and maintained in accordance with the Final Safety Analysis Report;

Whether the licensees vendor laboratory analyzed environmental samples under an approved quality control program and the inter-laboratory comparison program was adequate; and

Changes made to the environmental program.

The inspectors verified that when issues were identified, licensee personnel appropriately documented the issues in the CAP.

3.2 Observations and Findings There were no changes with respect to the monitoring of plant liquid or gaseous effluent pathways during this inspection period. The inspectors observed the licensee performing weekly air samples, weekly RETS water analysis, RIA-5211 turbine building sump Rad monitor Calibration, and monthly Palisades Park Commercial Well sampling. The inspectors noted during a review of the 2022 Annual Radioactive Effluent Release and Waste Disposal and Radiological Environmental Operating reports that no anomalous results, unexpected trends, or abnormal releases were identified in association with the plant activities. Since the last inspection, there were no spills or leakage associated with

plant activities requiring records to be maintained in accordance with 10 CFR 50.75(g).

The inspectors performed walkdowns of the plant on July 10-13, 2023, and observed that the effluent monitors were calibrated and consistent with the licensees procedures and ODCM.

No findings were identified.

3.3 Conclusions The effluent and environmental monitoring program elements reviewed aligned with descriptions in the Offsite Dose Calculation Manual. The effluent monitors reviewed were calibrated and alarm set points appropriately set to meet regulatory requirements.

Changes to the effluent and environmental monitoring program were consistent with regulatory requirements.

9.0 Exit Meeting The inspectors presented the results of the inspection to Mike Mlynarek and other members of the Palisades Nuclear Plant staff at an exit meeting on September 12, 2023.

The licensee acknowledged the results presented and did not identify any of the information discussed as proprietary.
