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.

OTHER ACTIVITIES - BASELINE

71152B - Problem Identification and Resolution Biennial Team Inspection (IP Section 03.04)

Main article: IP 71152

(1) The inspectors performed a biennial assessment of the effectiveness of the licensees Problem Identification and Resolution program, use of operating experience, self-assessments and audits, and safety conscious work environment.

Problem Identification and Resolution Effectiveness: The inspectors assessed the effectiveness of the licensees Problem Identification and Resolution program in identifying, prioritizing, evaluating, and correcting problems. The inspectors also conducted a five-year review of equipment aging issues.

Operating Experience: The inspectors assessed the effectiveness of the licensees processes for use of operating experience.

Self-Assessments and Audits: The inspectors assessed the effectiveness of the licensees identification and correction of problems identified through audits and self-assessments.

Safety Conscious Work Environment: The inspectors assessed the effectiveness of the stations programs to establish and maintain a safety-conscious work environment.

INSPECTION RESULTS

Assessment 71152B

1. Corrective Action Program Effectiveness

Problem Identification: The inspectors determined that the licensee was effective in identifying problems and entering them into the corrective action program and there was a low threshold for entering issues into the corrective action program. This conclusion was based on a review of the requirements for initiating condition reports as described in licensee procedure AD-PI-ALL-0100, "Corrective Action Program," and managements expectation that employees were encouraged to initiate condition reports. Additionally, site management was actively involved in the corrective action program and focused appropriate attention on significant plant issues.

Problem Prioritization and Evaluation: Based on the review of condition reports, the inspectors concluded that problems were prioritized and evaluated in accordance with the condition report significance determination guidance in procedure AD-PI-ALL-0100. The inspectors determined that adequate consideration was given to system or component operability and associated plant risk. The inspectors determined that plant personnel had conducted cause evaluations in compliance with the licensees corrective action program procedures and cause determinations were appropriate, and considered the significance of the issues being evaluated.

Corrective Actions: Based on a review of corrective action documents, interviews with licensee staff, and verification of completed corrective actions, the inspectors determined that corrective actions were timely, commensurate with the safety significance of the issues, and effective, in that conditions adverse to quality were corrected. For significant conditions adverse to quality, the corrective actions directly addressed the cause and effectively prevented recurrence. The inspectors reviewed effectiveness reviews to ensure corrective actions were properly implemented and were effective.

Based on the samples reviewed, the team determined that the licensees corrective action program complied with regulatory requirements and self-imposed standards. The licensees implementation of the corrective action program adequately supported nuclear safety.

2. Operating Experience

The inspectors determined that the station's processes for the use of industry and NRC operating experience information were effective and complied with all regulatory requirements and licensee standards. The implementation of these programs adequately supported nuclear safety. The inspectors concluded that operating experience was adequately evaluated for applicability and that appropriate actions were implemented to address lessons learned as needed.

3. Self-Assessments and Audits

The inspectors determined that the licensee effectively performed self-assessments and audits to identify issues at a low level, properly evaluate those issues, and resolve them commensurate with their safety significance. Self-assessments were generally detailed and critical. The inspectors verified that corrective action documents were initiated to document areas for improvement and findings resulting from self-assessments and verified that actions had been completed consistent with those recommendations. Quality assurance program audits appropriately assessed performance and identified areas for improvement.

4. Safety Conscious Work Environment

Based on safety culture interviews with plant personnel, reviews of the latest safety culture survey results, and interviews with employee concerns program personnel, the inspectors found no evidence of challenges to the safety conscious work environment. Employees appeared willing to raise nuclear safety concerns through at least one of the several means available.

Minor Violation 71152B Minor Violation: During the inspectors' review of the maintenance rule program implementation, specifically the documentation of local leak rate test (LLRT) 1SP-40 Pressurizer Liquid Space Sample Valve (IRC), 1SP-41 Pressurizer Liquid Space Sample Valve (ORC), 1SP-84 Safety Injection System Accumulator C Sample Valve (IRC), and 1SP-85 Safety Injection System Accumulator "C" Sample Valve (ORC), the maintenance rule evaluations concluded that a functional failure had occurred for each penetration. The licensees evaluation concluded that the failures were representative of a Repetitive Maintenance Rule Functional Failure (MRFF). In accordance with procedure AD-EG-ALL-1210, Maintenance Rule Program, Rev. 2, step 5.6.2.4.b, a Maintenance Rule (a)(1)evaluation was required for a Repetitive MRFF. Contrary to this procedure requirement, the inspectors found that no Maintenance Rule (a)(1) evaluation was completed. AD-EG-ALL-1210 is used to establish a program for implementing and maintaining the NRC Maintenance Rule as required by Title 10 of the Code of Federal Regulations (10 CFR) 50.65, Requirements for monitoring the effectiveness of maintenance at nuclear power plants. The inspectors determined the failure to accomplish step 5.6.2.4.b of AD-EG-ALL-1210 represents a violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings.

Screening: The inspectors determined the performance deficiency was minor. This performance deficiency was screened in accordance with Inspection Manual Chapter (IMC)0612 Appendix B, Issue Screening Directions, dated October 1, 2021, and was determined to be of minor significance because when the Maintenance Rule (a)(1) evaluation was completed for the repetitive MRFF, it was concluded that the initial maintenance rule evaluations failed to take into account the LLRT leakage test failures of each penetration were not in excess of the administrative limits as defined in EST-212, Type C Local Leak Rate Test, and were evaluated as acceptable in Engineering Change 419545. Therefore, the licensee ultimately concluded that the LLRT failures should not be considered functional failures, and thus no unacceptable performance occurred, and the barrier integrity cornerstone objectives were not adversely affected.

Enforcement:

This failure to comply with 10 CFR Part 50, Appendix B, Criterion V, constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy.

Observation: Residual Heat Removal (RHR) Breaker Failure Observation 71152B The inspectors reviewed Nuclear Condition Report (NCR) 02376252, originated on March 29, 2021, which documented a failure of the B RHR pump breaker during testing due to a termination that became loose over time and disconnected due to vibrations experienced during breaker cycling. The licensee had experienced a similar breaker failure in 2001, documented in NCR 29022, and recognized that the spade type connections had the potential of coming loose. Actions were initiated in 2001 due to the loose connection and a corrective action was implemented in PM-E0044, "480 VAC Siemens Type RLN(F) Load Center Breaker and Cubicle PM," that required the installation of Ty-Wraps near the connection point to reduce the probability of the connection from coming loose. The inspectors observed that the corrective actions implemented in 2001 did not prevent the failure of the RHR breaker in 2021. NCR 02376252 determined that PM-E0044 could be enhanced by directing the staff to ensure that spade type connections are confirmed to be tight to prevent slip on the connector. Additionally, a revision to PM-E0044 clarified that where the breaker frame is inaccessible Ty-Wraps are to be installed to fasten to adjacent wiring. The inspectors observed that NCR 02376252 did not clarify the as-found configuration of the Ty-Wraps installed on the RHR breaker connection that came loose. The inspectors observed that no similar failures have occurred since PM-E0044 has been revised with the updated guidance, however, the vendor design using slip on spade type connections is not optimum and that a design weakness still remains.

EXIT MEETINGS AND DEBRIEFS

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

On June 9, 2022, the inspectors presented the biennial problem identification and resolution inspection results to Ms. Kim Maza and other members of the licensee staff.
