EXECUTIVE SUMMARY

Kewaunee Power Station

NRC Inspection Report Nos. 05000305/2022001(DNMS)

The Kewaunee Power Station (KPS) is a permanently shutdown and defueled power reactor maintained in a Safe Storage (SAFSTOR) condition. This periodic safety inspection reviewed licensed activities associated with fire protection; occupational radiation exposure; radiological surveys; radioactive waste treatment, effluent, and environmental monitoring; and waste management and transportation.

Fire Protection Program An effective decommissioning Fire Protection Program was maintained and implemented that reasonably prevented fires; provided the capability to rapidly detect, control, and extinguish fires that could result in radiological hazards; and ensured the risk of fire-induced hazards to the public, environment, and plant personnel were minimized.

Occupational Radiation Exposure Adequate protection of worker health and safety from exposure to radiation and radioactive material was provided. Radiation surveys were performed adequately to identify the hazards present.

Radioactive Waste Treatment, and Effluent and Environmental Monitoring Changes to the environmental monitoring program were consistent with regulatory requirements.

Solid Radioactive Waste Management and Transportation of Radioactive Materials The licensee effectively processed, handled, stored, and transported radioactive material.

REPORT DETAILS

Summary of Plant Activities During this inspection period, the licensee maintained the unit in SAFSTOR conditions. No major decommissioning activities occurred during the inspection period.

1.0 Fire Protection Program at Permanently Shutdown Reactors (IP 64704)1.1 Inspection Scope The inspectors performed walkdowns, reviewed documents, and interviewed plant personnel to assess the licensees performance in the following areas:

Fire protection detection and suppression systems were effectively maintained, surveillances were performed, and systems were capable of performing their intended function; Fire barriers were effectively maintained; Firefighting equipment was properly inventoried, inspected, tested, and maintained; Administrative controls were in place to minimize the occurrence of a fire; and Staffing and training requirements were consistent with the Fire Protection Program and Emergency Plan.

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

1.2 Observations and Findings On June 1, 2021, the inspectors walked down the plant and the inspectors confirmed that the detection and suppression equipment was located where required, was being properly maintained, and could perform its intended function. The inspectors also verified that the fire barriers were effectively maintained. The inspectors also verified that firefighting equipment was properly inventoried, inspected, tested, and maintained. The inspector in addition interviewed the staff and verified the staff knowledge and training requirements were consistent with the Fire Protection Program and Emergency Plan.

No findings were identified.

1.3 Conclusions An effective decommissioning Fire Protection Program was maintained and implemented that reasonably prevented fires; provided the capability to rapidly detect, control, and extinguish fires that could result in radiological hazards; and ensured the risk of fire-induced hazards to the public, environment, and plant personnel were minimized.

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:

Training and qualifications of members of the Radiation Protection (RP) organization; Radiological hazards and worker protection in work activities; Radiological controls, postings, and material conditions inside the radiological control area; Contamination monitoring including release of radioactive materials from controlled areas; Accuracy and functionality of radiation monitoring instruments; and The characterization of the radiation type and energies were appropriate to the surveys and work practices; and staffing, posting, radiological controls, and changes met regulatory requirements.

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

2.2 Observations and Findings Currently, there are no changes to the organization staffing and instrumentation that will impact RP. However, the inspectors discussed with the licensee the site transition once active decommission begins at Kewaunee. Specifically, the inspectors interviewed licensee management about the potential organization staffing plan, RP procedures, and instrumentation requirements that will be implemented onsite. The current Kewaunee management staff indicated to the NRC inspectors that staffing, instrumentation plans, and site RP procedure plans are being actively discussed with EnergySolutions to ensure that the site will have the necessary staffing, instrumentation, and RP procedures once active decommissioning begins. The inspectors also reviewed the organization chart of EnergySolutions staff once active decommissioning starts.

The inspectors also reviewed the licensees training records and determined that all personnel were appropriately trained, and training activities were documented in accordance with the approved procedures. The inspectors reviewed the licensees radiation and contamination surveys, air samples, and source inventory. The inspectors observed the licensees vendor performing radiation surveys of various warehouses.

The inspectors verified that for each type of survey the licensee performed, staff used the appropriate survey instrument to perform these surveys and that the licensee was updating its source term that was currently onsite due to source decay.

The inspectors also performed a walkdown of the plant. The inspectors observed that general housekeeping was maintained and that all signs within the plant were appropriately posted and legible. The inspectors also observed that all radioactive material was properly bagged, tagged, and controlled.

No findings were identified.

2.3 Conclusions Adequate protection of worker health and safety from exposure to radiation and radioactive material was provided. Radiation surveys were performed adequately to identify the hazards present.

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:

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; 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 CAP; 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 issue in the CAP.

3.2 Observations and Findings The inspectors reviewed the licensees Radiological Environmental Monitoring Program (REMP) and the associated vendor procedures to ensure that the licensee obtained and analyzed the appropriate environmental samples in accordance with the applicable regulatory requirements and REMP program. The inspectors also observed the licensees environmental monitoring vendor obtaining water samples from the lake and grass samples from areas around the station. The licensees vendor obtained the samples from the appropriate location in accordance with its procedures and had the applicable equipment and documentation. The inspector verified that the licensees vendor performed the environmental sampling analysis and followed and evaluated its results in accordance with its approved quality control program. There were no changes to the environmental program.

No findings were identified.
