AUTOMATIC REACTOR TRIP
The following information was provided by the licensee via phone and email:
"Surry Unit 1 reactor automatically tripped at 1708 EDT on 6/2/24 due to a turbine trip [with the reactor operating at greater than 10 percent reactor power].
"The turbine control system is currently under investigation. Reactor coolant temperature is being maintained via main steam dumps with main feedwater supplying the steam generators.
"All systems operated as required. The trip was uncomplicated and all control rods fully inserted into the core. There was no emergency core cooling system (ECCS) or auxiliary feedwater system actuation. Offsite power remains available. There is no impact to Surry Unit 2.
"This notification is being made pursuant to 10 CFR 50.72(b)(2)(iv)(B) for 4-hour notification of reactor protection system activation. The NRC Resident Inspector has been notified.
"There were no radiation releases, personnel injuries, or contamination events due to this event."
