PLANT STATUS

Unit 3 operated at or near rated thermal power (RTP) for the entire inspection period.

Unit 4 began the inspection period at RTP. On February 27, 2025, the unit reduced power to 44 percent RTP for main steam safety valve testing. On March 1, 2025, the unit was taken offline for refueling outage, PT4-35, where the unit remained for the rest 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.

71114.01 - Exercise Evaluation

Inspection Review (IP Section 02.01-02.11) (1 Sample)

(1) The inspectors evaluated the biennial emergency plan exercise during the week of February 10, 2025. The simulated scenario began with condensate pump discharge flange leakage, which led to lowering steam generator levels and a manual reactor trip. At the moment the reactor was tripped, a loss of all offsite AC power was experienced, and an Unusual Event was declared. A short time later, the emergency diesel generator failed, which met the conditions for declaring an Alert. As the event progressed, a reactor coolant system (RCS) leak began, and then increased until a containment spray actuation signal occurred. When the containment spray pump failed to start, emergency action level conditions were met, and a Site Area Emergency was declared. The scenario provided opportunities for the offsite response organizations to demonstrate their ability to implement emergency actions.

71114.04 - Emergency Action Level and Emergency Plan Changes

Inspection Review (IP Section 02.01-02.03) (1 Sample)

(1) The inspectors evaluated submitted Emergency Action Level, Emergency Plan, and Emergency Plan Implementing Procedure changes during the week of February 10, 2025. This evaluation does not constitute NRC approval.
