AUTOMATIC REACTOR TRIP FROM FULL POWER DUE TO A FAILED FEED FLOW CHANNEL
"'A' Steam Generator hi/hi level caused a turbine trip which in turn caused a Unit 1 reactor trip. The hi/hi steam generator level also caused both feedwater pumps to trip which caused the auxiliary feedwater pumps to auto-start. The hi/hi level also caused a feedwater isolation. Appropriate emergency procedures have been implemented and the plant is currently stable."
All control rods fully inserted on the trip. Offsite power is available and powering safety related buses. The emergency diesel generators are available if required. There are no known primary to secondary leaks in the steam generators.
The licensee will notify the NRC Resident Inspector.
