SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Joseph M. Farley Nuclear 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 began the inspection period at approximately 100 percent rated thermal power (RTP). On August 3, 2022, the unit was automatically shut down due to an automatic shutdown of the main turbine/generator. The turbine/generator shutdown was caused by a maintenance activity that inadvertently isolated the main generator from the 230 kilovolt (kV) bus no. 1. The unit was restarted on August 5, 2022 and returned to approximately 100 percent RTP on August 7, 2022.

On August 21, 2022, power was reduced to approximately 97 percent RTP to address a feedwater heater valve. The unit was returned to approximately 100 percent RTP on August 24, 2022. On August 27, 2022, the unit began coasting down until approximately 80 percent RTP was achieved on September 18, 2022. The unit was then shutdown on September 18, 2022 for a planned refueling outage (1R31) and remained there through the end of the report period.

Unit 2 began the report period at approximately 100 percent RTP and remained at or near 100 percent RTP through the end of the report 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.
