AUTOMATIC REACTOR TRIP DURING STARTUP
"On 08/19/20 at 1325 EDT, during Unit 3 startup at approximately 0 percent rated thermal power, the reactor automatically tripped. The trip was automatically initiated from the Source Range Nuclear Power Instrumentation. All other systems operated normally. Operations stabilized the plant in Mode 3. Decay heat is being removed by Steam Dumps. Unit 4 is not affected.
"This event is being reported pursuant to 10 CFR 50.72(b)(2)(iv)(B).
"The NRC Resident Inspector has been notified."
The cause of the Source Range Nuclear Power Instrumentation trip is under investigation.
