COMPLETED BY A. G. Neufer l
80-01 Unit was being removed f rom service for a scheduled turbine overspeed test.
When the last generater output breaker was opened, the turbine and reactor tripped. An improperly set transmitter PT-MS-232 caused turbine valves to j
pulse open raising the 1st stage press to greater than 10% (turbine power greater than 10% with generator output breakers open causes a turbine trip) j' resulting in a turbine trip and reactor trip.
l 80-02 When the Overspeed Protection Controller pulsed during the planned overspeed test it caused First Stage Impulse Pressure to go greater than 10% inducing a signal te reinstate the at-power trips.
t I
80-03 Condensate Pump Suction Strainers clogged up causing a loss of Feedwater Flow.
