Event Text

AUTOMATIC REACTOR TRIP ON LOW LOW STEAM GENERATOR WATER LEVEL.


"An automatic Reactor Trip occurred on 21 Steam Generator low low level. The cause is currently under investigation. All systems responded as required. All control rods fully inserted. All auxiliary Feedwater pumps started as expected, on the low level signals and the steam driven auxiliary feed (23) pump was secured by procedure. Currently the steam dump system is rejecting heat to the main condenser for reactor coolant system temperature control, currently at normal operating temperature and pressure. No major equipment was unavailable at the time of the trip."

All Emergency Core Cooling Systems and the Emergency Diesel Generators are fully operable if needed and the electrical grid is stable.

The Licensee is investigating the cause of Steam Generator "21" low low water level.

The NRC Resident Inspector was notified of this event by the licensee.
