SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at North Anna Power Station, Units 1 and 2, 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.
PLANT STATUS
Unit 1 began the inspection period shutdown for Refuel Outage 1R29. The unit was restarted, and the generator was synchronized to the grid on October 26. The unit reached rated thermal power on October 28, where it continued to operate for the remainder of the inspection period.
Unit 2 began the inspection period operating at or near rated thermal power, where it remained through the end of the inspection period.
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 performed activities described in IMC 2515, Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of IPs. 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.

- (1) The inspectors reviewed the licensees corrective action program for potential adverse trends in pump vibrations and oil analysis that might be indicative of a more significant safety issue.
INSPECTION RESULTS
Observation: Semi-Annual Trend Review of Oil and Vibration Analysis 71152S The inspectors reviewed the licensee's corrective program to determine if a potentially adverse trend existed in human performance or equipment reliability related to increased vibrations and oil particulates for various pumps and motors, which could be indicative of a more significant safety concern. Specifically, the inspectors reviewed the following condition reports generated in the last year related to particulate discovered in oil samples for 01-CN-P-1B (Unit 1 B condensate pump) and 1-CH-P-1C-MOTOR (Unit 1 C charging pump) and elevated vibrations in pumps 1-FC-P-1B (B spent fuel pit cooling pump), 2-FW-P-3A (A motor-driven auxiliary feedwater pump), and 1-SW-P-4 (no. 4 auxiliary service water pump):
CR1203250, CR1202766, CR1206113, CR1198472, CR1202941 The inspectors noted that the station independently evaluated each issue, however the corrective actions and evaluations did not consider if a common-cause or theme for degradation existed in pumps across different systems. The inspectors noted the stations process for trending similar components across various systems focused primarily on components on the stations top equipment list and that based on this approach there may be a common cause or contributor that has not been evaluated.
In addition to the broader trend discussion, the inspectors questioned how station personnel identified degrading oil color quality. The inspectors noted the stations procedure evaluates oil quality by visually identifying color changes using a visual aid across a spectrum which the inspectors determined to have many gradations. These gradations were so similar in color that the inspectors asked maintenance personnel how they would determine two color changes, which is the procedural criteria to determine if a sample is unsatisfactory. Station personnel acknowledged the inspectors concern and informed the inspectors that action was being pursued to evaluate a more reliable method to be used.
No findings of significance were identified as a result of this inspection.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
On January 25, 2023, the inspectors presented the integrated inspection results to Mr.
James Jenkins, Nuclear Plant Manager, and other members of the licensee staff.
