Entergy Corp’s 1,022-megawatt (MW) Unit 2 at the Indian Point nuclear power plant in New York started to exit an outage, according to the U.S. Nuclear Regulatory Commission (NRC).
UNIT 2 EXPERIENCED AN AUTOMATIC REACTOR TRIP ON TURBINE MAIN GENERATOR TRIP
“On June 6, 2012, at approximately 0612 hours, Indian Point Unit 2 reactor automatically tripped from 100% steady state power due to a turbine-main generator electrical trip.
Investigation into the generator trip is in progress.
The Auxiliary Feedwater system actuated and responded as expected and is maintaining steam generator levels.
Decay heat removal is via the steam generators to the main condenser. Offsite power and plant electrical lineups are normal.
No primary or secondary code safety relief valves lifted.
The reactor is in Mode 3 and stable. Unit 3 was unaffected and remains at 100% power.”
The NRC Resident Inspector has been notified, and the licensee issued a press release.
