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 in refueling outage cycle 31 (1R31). On December 21, 2022, unit 1 reactor was taken critical and entered mode 1 on December 22, 2022. Over a period of approximately six days rated thermal power (RTP) was increased with various hold points for testing until December 28, 2022, when unit 1 achieved approximately 100 percent RTP. Unit 1 remained at approximately 100 percent RTP 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.
