SUBJECT:

NORTH ANNA POWER STATION, UNITS 1 AND 2 - BIENNIAL PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION REPORT 05000338/2019011 AND 05000339/2019011

Dear Mr. Stoddard:

On November 7, 2019, the U.S. Nuclear Regulatory Commission (NRC) completed a problem identification and resolution inspection at your North Anna Power Station, Units 1 and 2. On November 7, 2019 the NRC inspectors discussed the results of this inspection with Mr. Jim Jenkins and other members of your staff. The results of this inspection are documented in the enclosed report.

The NRC inspection team reviewed the stations corrective action program and the stations implementation of the program to evaluate its effectiveness in identifying, prioritizing, evaluating, and correcting problems, and to confirm that the station was complying with NRC regulations and licensee standards for corrective action programs. Based on the samples reviewed, the team determined that your staffs performance in each of these areas adequately supported nuclear safety.

The team also evaluated the stations processes for use of industry and NRC operating experience information and the effectiveness of the stations audits and self-assessments.

Based on the samples reviewed, the team determined that your staffs performance in each of these areas adequately supported nuclear safety.

Finally, the team reviewed the stations programs to establish and maintain a safety-conscious work environment and interviewed station personnel to evaluate the effectiveness of these programs. Based on the teams observations and the results of these interviews the team found no evidence of challenges to your organizations safety-conscious work environment. Your employees appeared willing to raise nuclear safety concerns through at least one of the several means available. No NRC-identified or self-revealing findings were identified during this inspection.

A licensee-identified violation which was determined to be of very low safety significance is documented in this report. We are treating this violation as a non-cited violation (NCV)

consistent with Section 2.3.2 of the Enforcement Policy.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.

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 02.04)

  • Corrective Action Program Effectiveness: The inspectors assessed the corrective action programs effectiveness in identifying, prioritizing, evaluating, and correcting problems.
  • Operating Experience, Self-Assessments and Audits: The inspectors assessed the effectiveness of the stations processes for use of operating experience, 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 Corrective Action Program Assessment: Based on the samples reviewed, the team determined that the licensees corrective action program (CAP) complied with regulatory requirements and self-imposed standards. The licensees implementation of the CAP adequately supported nuclear safety.

Effectiveness of Problem Identification: The inspectors determined that the licensee was effective in identifying problems and entering them into the CAP at the appropriate threshold. This conclusion was based on a review of the requirements for initiating condition reports (CRs) as described in licensee procedure PI-AA-200, "Corrective Action Program,"

and the site's management 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. The inspectors performed walk downs, reviewed CRs, and reviewed system health trending for Diesel Generators and emergency AC power, the Service Water System, and the Low Head Safety Injection System. Based on the inspectors' reviews and walk downs of accessible portions of those systems, the inspectors determined that deficiencies were being identified and placed in the CAP.

Effectiveness of Problem Prioritization and Evaluation: Based on the review of CRs sampled by the inspection team during the onsite period, the inspectors concluded that problems were prioritized and evaluated in accordance with the CAP requirements described in procedure PI-AA-200. The inspectors determined that adequate consideration was given to system or component operability and associated plant risk. The inspectors determined that plant personnel had generally conducted cause evaluations in compliance with the licensees CAP procedures, including appropriate cause determinations, and performed adequate levels of analysis based on the significance of the issues being evaluated.

Effectiveness of 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 effective, timely, and commensurate with the safety significance of the issues. For significant conditions adverse to quality, the corrective actions directly addressed the cause and effectively prevented recurrence. The inspectors reviewed performance indicators, CRs, and effectiveness reviews, as applicable, to verify that the significant conditions adverse to quality had not recurred. Effectiveness reviews for corrective actions to preclude repetition (CAPRs) were sufficient to ensure corrective actions were properly implemented and were effective.

Assessment 71152B Operating Experience, Self-Assessments, and Audits: The inspectors examined the licensee's program for obtaining and using industry operating experience. This included a review of procedure PI-AA-100-1007, "Operating Experience Program," selected corrective action program action requests, and the licensees operating experience (OE) database to assess the effectiveness of how external and internal OE data was evaluated at the plant. Additionally, the inspectors selected OE documents such as NRC generic communications, licensee event reports, vendor notifications, and plant internal OE items which had been issued since July 2017 to verify that the licensee had appropriately evaluated each notification for applicability to the station, and whether issues identified through these reviews were entered into the CAP.

The inspectors determined that the scopes of assessments and audits were adequate. Self-assessments were generally detailed and critical. The inspectors verified that condition reports (CRs) were created to document areas for improvement and findings resulting from self-assessments and verified that actions had been completed consistent with those recommendations. Audits of the quality assurance program appropriately assessed performance and identified areas for improvement. Generally, the licensee performed evaluations that were technically accurate.

The inspectors determined that the station's processes for the use of industry and NRC operating experience information and for the performance of audits and self assessments 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. The inspectors determined that the licensee was effective at performing self-assessments and audits to identify issues at a low level, properly evaluated those issues, and resolved them commensurate with their safety significance.

Assessment 71152B Safety Conscious Work Environment: Based on a sample of 25 individuals interviewed from a cross-section of plant employees, the inspectors found no evidence of challenges to the safety conscious work environment. Employees interviewed appeared knowledgeable of avenues to raise safety concerns and appeared willing to raise nuclear safety concerns through at least one of the several means available.

Licensee-Identified Non-Cited Violation 71152B This violation of very low safety significance was identified by the licensee and has been entered into the licensee corrective action program and is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Violation: North Anna Technical Specifications 5.4, Procedures, paragraph 5.4.1 required in part that written procedures shall be established, implemented and maintained covering the applicable procedures recommended in Regulatory Guide (RG) 1.33, Rev. 2, Appendix A, dated February 1978. RG 1.33, Quality Assurance Program Requirements (Operations),

Rev. 2, Appendix A, section 9.b required in part that preventive maintenance schedules should be developed to specify inspections of equipment. Licensee Procedure 0-MPM-1207-04, Annual Pumping of Security and Electrical Cable Vaults, Rev. 10, implemented this requirement for certain safety related (SR) medium voltage cables. Contrary to the above, the licensee failed to inspect (SR) medium voltage cables susceptible to water submergence in accordance with this procedure. Licensee procedure 0-MPM-1207-04 required annual pumping and inspections of SR medium voltage cables susceptible to submergence to prevent long term submergence of electrical cables which could lead to cable degradation. According to the licensee, the annual inspections have not occurred since 2016.

Significance/Severity: Green. This violation was screened to Green, very low safety significance in accordance with IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings at Power, dated June 19, 2012, Exhibit 2, Mitigating Systems Screening Questions because all of the screening questions were answered No.

Corrective Action References: This issue was documented in the licensees corrective action program (CAP) as condition report (CR) 1133235.

Minor Violation 71152B Minor Violation: The NRC identified a minor violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to ensure that instructions, procedures, or drawings were appropriate for the circumstances. Specifically, the licensee failed to ensure that maintenance procedure 0-MPM-0452-18, Visual Inspection of Damper for Condition of External Duct Work, Operator, Hardware and Operation, and the model preventive maintenance (PM) work orders (WO) included adequate instructions for inspection of the Control Room and Emergency Switchgear Air Handlers.

Following a failure of the main control room chiller fan discharge damper to open when the fan was started, the licensee revised maintenance procedure 0-MPM-0452-18 to include instructions for mechanical inspection of the damper linkages. The inspectors reviewed the maintenance procedure and observed that the Note added prior to step 6.2.3 in the procedure failed to direct action to use a wrench to test for tightness.

Screening: The inspectors determined the performance deficiency was minor. The performance deficiency was screened in accordance with Inspection Manual Chapter 0612 Appendix B. The inspectors determined the performance deficiency was minor because no subsequent failures of the main control room chiller discharge dampers have occurred. This issue was captured in CR 11135344.

Enforcement:

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

EXIT MEETINGS AND DEBRIEFS

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

  • On November 7, 2019, the inspectors presented the biennial problem identification and resolution inspection results to Mr. Jim Jenkins and other members of the licensee staff.
