SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a license renewal Phase IV inspection at Beaver Valley Power Station, Unit 1, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.

List of Findings and Violations

No findings or violations of more than minor significance were identified.

Additional Tracking Items

None.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html.

Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

===71003 - Post-Approval Site Inspection for License Renewal

The team conducted a Phase IV license renewal inspection as outlined in NRC IP 71003. The team selected seven aging management programs for evaluation based on risk insights and programs that were enhanced or new under the renewed operating license. The team also considered for selection those programs with monitoring results that were performed for the first time or those that identified examination or test results not experienced in the past. For the aging management programs selected, the team reviewed records, interviewed plant staff, and conducted plant walk downs to evaluate whether aging management program elements were being implemented in accordance with NRC requirements. The team evaluated the following elements of the aging management programs: scope, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, acceptance criteria, corrective actions, confirmation process, administrative controls, and operating experience.

The following aging management programs were evaluated by the team:

Post-Approval Site Inspection for License Renewal===

(1) External Surfaces Monitoring Program

(2) Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program

(3) Buried Piping and Tanks Inspection Program

(4) Selective Leaching Program

(5) Structures Monitoring Program

(6) Electrical Cables and Connections Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program

(7) Inaccessible Medium Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program

INSPECTION RESULTS

Observation: Wetted cables during annual manhole inspection 71003 The inspectors reviewed the licensee's implementation of the Inaccessible Medium Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program. The inspectors selected a random sample of manhole inspections from the past three years. The licensee discovered high water levels, sometimes on a repeated basis, during the manhole inspections where the cables were submerged (i.e., wetted). During each occurrence, the licensee drained the water from the manhole, but did not take actions to adjust the frequency to minimize the exposure to moisture as required by procedure 1/2-ADM-2404, Revision 5. The Unit 1 cables in-scope for license renewal under the aging management program are the three river water pumps 1A/B/C and the emergency response facility feeder cable FDR-1/2. The licensee generated condition report CR-2024-7442 to identify the trend in high water level for two of the manholes. The inspectors noted that repeated wetting of the electrical cables could result in long-term degradation of cable insulation. The inspectors determined the issue was minor because the licensee had performed periodic electrical testing (i.e., megger) of these cables which served to monitor the capability of the cable insulation. The inspectors reviewed the most recent test results and noted the acceptance criteria had been met.

Observation: Selective leaching commitment change 71003 The inspectors observed that the licensee changed their license renewal commitment for the selective leaching program in 2020 to perform no additional inspections of the gray cast iron buried components, and instead, to manage the effects of aging under the fire protection program. The basis was condition monitoring of above ground components would be an effective alternative monitoring method. However, the inspectors determined there was not guidance in the fire protection program for sampling or monitoring for selective leaching. The licensee had identified this performance deficiency and entered it into their corrective action program during a July 2024 self-assessment. The inspectors determined this issue was minor because the previous guidance remained available under the active procedure 1/2-ADM-2303, Revision 2, Selective Leaching of Materials Inspection Program.

The inspectors also noted that the licensee performed an opportunistic inspection of a buried gray cast iron component in 2017 after a fire protection pipe failure occurred, which met this license renewal commitment prior to its change.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

• On September 26, 2024, the inspectors presented the license renewal Phase IV inspection results to Will Cothen, Site Engineering Director and other members of the licensee staff.

• On September 12, 2024, the inspectors presented the preliminary inspection results to Barry Blair, Site Vice President, and other members of the licensee staff.
