WASHINGTON, Nov. 15 -- The Nuclear Regulatory Commission issued the following event notification (No. 55572) involving Beaver Valley, Pennsylvania:


"At 1007 EST on November 12, 2021, with Unit 2 in Mode 1 at approximately 17 percent power following a refueling outage, the reactor was manually tripped due to increasing steam generator water levels due to an oscillating Main Feedwater Pump Recirculation Valve. Additionally, the Main Steam Isolation Valves were manually closed to prevent excessive reactor coolant system cooldown. Decay heat is being removed by discharging steam to the atmosphere using the Atmospheric Dump Valves.

"The trip was not complex, with all systems responding normally post-trip. There was no equipment inoperable prior to the event that contributed to the reactor trip or adversely impacted plant response. Operations responded and stabilized the plant.

"Beaver Valley Power Station Unit 1 is unaffected and remains at 100 percent power in Mode 1.

"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."
