EVENT 03-4 CAUSE: TURBINE TRIP / REACTOR TRIP DUE TO LOW ELECTROIlYDRAULIC CONTROL (EllC) SYSTEM PRESSURE.

TIIE DIRECT CAUSE OF Tills EVENT WAS A FAILURE OF Tile *A" EllC PUMP, ALONO WITil TIE FAILUIE OF TIE STANDBY ElIC PUMP TO AUTO START AT Tile CORRECT PRESSURE. TIIE COMBINATION OF TIIE TWO FAILURES PREVENTED TIIE EllC PUMPS FROM PROPERLY M.AINTAINING EllC PRESSURE.

1 CORRECTIVE ACTION: TIE DEFECTIVE EllC PUMP WAS REPLACED, AND TlIE ElIC SYSTEM WAS DRAINED AND REFILLED PRIOR TO BEING RESTORED TO SERVICE. Tile LOW EllC PRESSURE ALARM AND STANDBY PUMP AUTOSTART PRESSURE SWITCIIES WERE CALIBRATED AND ADJUSTED TO TIIE CORRECT SETPOINTS.
