SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Vogtle Electric Generating Plant, Units 1 & 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 operated at or near rated thermal power for the entire inspection period.

Unit 2 began the inspection period operating at 100 percent rated thermal power (RTP). On December 1, 2019, power on the unit was reduced to approximately 83 percent RTP due to increased sodium levels resulting from a leak inside the 2A condenser. On December 5, power on the unit was increased to approximately 90 percent RTP as repairs were conducted inside the condenser. On December 9, power on the unit was reduced from approximately 90 percent RTP to approximately 77 percent RTP due to outside ambient temperature effects on the unit. On December 11, following completion of repairs inside the 2A condenser, the unit was returned to operating at 100 percent RTP, where it continued to operate 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.

INSPECTION RESULTS

Observation: Semi-annual Trend Review Associated with Missed Fire Watches 71152 During a semi-annual trend review, the inspectors noted an increased trend in missed fire protection watches. Specifically, during their review of fire watch logs for both units, the inspectors identified examples where hourly fire watches were not completed within the 60 to 75 minutes allotted by procedure. The inspectors discussed their observations with the licensee and interviewed Operations personnel regarding the missed fire watches. During the interview, the inspectors learned that the missed fire watches had been previously identified by the licensee and corrective actions were implemented as a result. One of the causes identified was attributed to changes in contractors responsible for implementation of the fire watches. The corrective actions taken to address the causes included coaching and implementation of a standing order to reinforce the requirements for performing fire watches within the specified time frame. In addition, the inspectors performed a review of fire watches conducted after implementation of the licensee's corrective actions, and while the inspectors did not identify additional examples of missed fire watches, the inspectors noted the need for continued monitoring and trending in this area due to the licensee's intent to change fire watch contractors in the near future.

EXIT MEETINGS AND DEBRIEFS

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

• On January 17, 2020, the inspectors presented the integrated inspection results to Mr. Keith Taber and other members of the licensee staff.
