Reactor Trip during Plant Protection System Surveillance Testing
PLANT STATUS
Unit 1 entered the inspection period at full power. On March 27, 2022, the unit began a coastdown for refueling outage 1R23.
Unit 2 entered the inspection period at full power. On January 24, 2022, the unit shut down for short notice outage 2M24A to repair a nitrogen leak on safety injection tank 1A and perform repairs on high pressure feedwater heater 5A. On February 6, 2022, the reactor was made critical following completion of the short notice outage and returned to full power on February 8, 2022, where it remained for the remainder of the inspection period.
Unit 3 operated at or near full power for the duration 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.
