SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Prairie Island Nuclear Generating Plant, 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 operated at or near rated thermal power for the entire inspection period with the exception of brief power reductions to perform surveillance testing or flexible power operations.

Unit 2 began the inspection period at rated thermal power. On May 27, 2023 at 6:19 p.m., the Unit 2 turbine generator and reactor tripped. The unit was taken critical on June 1, 2023 at 2:43 p.m., and was synched to the grid on June 2, 2023 at 7:50 a.m., ending the Unit 2 forced outage. The unit was raised to approximately 50 percent rated thermal power on June 3, 2023 at 3:36 a.m. and remained there. On June 7, 2023 at 1:00 a.m., Unit 2 commenced shutdown from approximately 50 percent power and the reactor was tripped at 3:33 a.m. Unit 2 reactor was taken critical on June 16, 2023 at 3:48 a.m. The unit was returned to full-rated thermal power on June 17, 2023 at 12:32 p.m., and remained at or near rated thermal power for the remainder 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.

INSPECTION RESULTS

Observation: Annual Follow-up D5/D6 Storage Vault Tank and Piping Material Condition 71152A Inspectors performed an annual follow-up sample of CAPs 501000054198, 501000054985, 500000317360, 501000064012, and 501000064279, associated with the material condition of the D5/D6 fuel oil storage tank (FOST) vaults and piping. These CAPs were associated with material issues and a non-cited violation identified in August of 2021. In 2019, a hole was discovered in the 23 FOST suction line due to exterior corrosion. A temporary modification (T-mod) was put into place as a compensatory measure. In 2021, based upon questions from the NRC, the T-mod was removed, and the section of piping was replaced. During the work in the vaults and subsequent inspections, additional degradation of the vaults, tanks, and the piping was identified. Subsequent preventive maintenance activities completed since August of 2021 have resulted in unmet acceptance criteria. Inspectors did not identify any substantive actions which have been taken to correct these issues to date. However, piping repairs are currently scheduled to occur during the upcoming refueling outage starting October 6, 2023. The licensee has recently conducted challenge meetings to ensure readiness to complete the corrective maintenance activities. In addition, high impact team (HIT) meetings are being conducted weekly to ensure alignment and preparedness to complete the work. The inspectors did not identify any more-than-minor findings or violations during this review.

Observation: Trend Review - Security Behaviors 71152S Inspectors assessed a cognitive trend they observed regarding security behaviors of site personnel. Based upon personal observations and recent CAPs, inspectors questioned if site personnel were ensuring strict compliance with security policies and procedures. Inspectors discussed their observations with the security manager and site supervision.

CAP 501000074816, NRC Observation - Security Gate Use Trend, was initiated by the licensee. Following CAP initiation, the issue was discussed at the 6:30 a.m.

plan-of-the-day (POD) meeting. In addition, on June 27, 2023 and June 29, 2023, the plant manager update videos featured discussions of poor security behaviors and delay gate standards messaging to all site personnel. Although not fully affective in curbing the potential adverse trend, the inspectors did note marked improvements of personnel security behaviors.

Discussions with the security manager indicated that additional actions were planned to correct the observed behaviors as well. The NRC-identified trend CAP has an ongoing action which is due on August 28, 2023. The inspectors did not identify any more-than-minor findings or violations during this review.

Observation: Semi-annual Trend of ES4 Detectors Out of Service 71152S The inspectors selected the security equipment reliability trend of ES4 detectors for a semi-annual review to identify potential trends that might indicate the existence of a more significant issue. Inspectors reviewed corrective action documents related to repetitive issues with equipment which caused operational burden on the security and instrumentation and control departments. Inspectors reviewed procedures and conducted interviews with security department personnel concerning the potential negative equipment trend. Inspectors also interviewed instrumentation and control department personnel with respect to the assessment of operating experience related to the new detectors. Additionally, inspectors reviewed the corrective actions taken in response to the repetitive issues associated with the security equipment and did not identify any new issues. One notable observation was that it was not clear to some individuals closing corrective action documents that there is a process for documenting objective evidence for CAP closure of safeguard-related CAPs in the safeguard computer systems at the site. The inspectors did not identify any findings or violations of more-than-minor significance.
