AUTOMATIC REACTOR TRIP WHILE PERFORMING TESTING
“On July 6, 2016 at 0938 EDT Indian Point Unit 2 experienced a trip from 100% steady state power during the performance of reactor protection testing. The cause of the trip is under investigation.
“All control rods fully inserted and all systems responded as expected. The auxiliary feedwater system actuated as expected on a low level in the steam generators which occurs as a result of a trip from full power. Auxiliary feedwater is maintaining steam generator levels and decay heat removal is via the steam generators to the main condenser.
“Offsite power and plant electrical line ups are normal with the exception of 13.8kV feeder 33332 which remains out of service during the replacement of breaker BT4-5.
“No primary or secondary code safety relief valves lifted. The reactor is in Mode 3 and stable.
“Indian Point Unit 3 was unaffected and remains at 100% steady state power.
“The NRC Resident Inspector has been notified.”
The licensee notified the New York Public Service Commission and the New York Independent System Operator. Indian Point indicated they have issued a press release regarding the event.
