Power reduction to 65% to perform Maximum Core Flow/Prompt Flow Control Line Determination test, investigate Main Condenser air in-leakage and to adjust control rods and precondition fuel.
Power operation.
Reactor shutdown following scram.
Failure of the Pressure Control System caused a load reject signal.
The return to power was delayed by the failure of MO-2076, RCIC Steam Line Isolation Outboard, during startup, and subsequent repair.
Reduced power operations during startup for scram recovery.
Power operation.
Note: Power operation defined as essentially 100% of rated power except for weekend load drops for specified surveillance testing.
