AUTOMATIC REACTOR SCRAM

The following information was provided by the licensee via email:

"At 0001 EDT on September 26, 2022, James A. FitzPatrick (JAF) removed the generator from service as part of a planned shutdown for refueling.

"At 0306 EDT, with the mode switch in Startup/Hot Standby and inserting rods, JAF experienced a spurious Scram and closure of seven out of eight main steam isolation valves (MSIV's). The reactor protection system (RPS) actuated during the event, resulting in all control rods being fully inserted.

"The cause of the closure of MSIV's and the Scram is being investigated.

"This condition is being reported as a four-hour NRC report per 10 CFR 50.72(b)(2)(iv)(B) for RPS actuation, and as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(iv)(A) for the safety system actuation based on the multiple main steam isolation valves closing on an isolation signal.

"There was no impact to the health and safety of the public. The NRC Resident Inspector has been notified."

MANUAL REACTOR TRIP DUE TO REPORTED FIRE ON ISOPHASE BUS DUCT
The following information was provided by the licensee via fax email:
"At 0238 CDT on 9/26/2022 with Unit 2 in Mode 1 at 100 percent power, the reactor manually tripped due to a reported fire on the isophase bus duct. The trip was uncomplicated with all systems responding normally post-trip with the exception of the 2A reactor protection system power supply, which tripped and power was transferred to the alternate source. The fire was reported extinguished at 0240 CDT on 9/26/2022. 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).

"Operations responded using the emergency operating procedure LGA-001 and stabilized the plant in Mode 3. Decay heat is removed by discharging steam to the main condenser using the turbine bypass valves. Unit 1 is not affected.

"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
