MANUAL REACTOR SCRAM
The following information was provided by the licensee via phone and email:
"At 0303 EST on 02/26/26, with Unit 1 in mode 2 at 1 percent power, the reactor was manually tripped as required by procedure due to balance of plant equipment not responding as expected. The trip was not complex, with all systems responding normally post-trip.
"Operations responded and stabilized the plant. Reactor water level is being maintained via the control rod drive (CRD) and reactor water cleanup (RWCU) systems. Decay heat is being removed by the RWCU system. Unit 2 is not impacted.
"Due to the reactor protection system actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B).
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
