SUPPLEMENT TO CAUSE DESCRIPTION TIME. (2) THE INVERTER FOR GOVERNOR POWER HAD FAILED. THE ISOLATION VALVES FOR XPS-228 AND XPS-229 WERE OPENED AND THE INVERTOR WAS SWITCHED TO AN ALTERNATE POWER SUPPLY. THE DIESEL WAS THEN STARTED AND RAN PROPERLY.

THESE VALVES ARE PRESUMED TO HAVE BEEN SHUT DURING A PREVIOUS CALIBRATION CHECK OF THE SPEED INDICATOR. TO PREVENT RECURRENCE, TRAINING WAS HELD WITH ALL CSI PERSONNEL INFORMING THEM OF THE CONSEQUENCES OF LEAVING INSTRUMENTS ISOLATED.

THE INVERTER WAS REPAIRED BY REPLACING AN OSCILLATOR BOARD ¹V091B, MANUFACTURERED BY SOLID STATE CONTROLS, INC. THE SURVEILLANCE TEST WAS THEN COMPLETED SATISFACTORILY.

THE COMPLETION OF THE" SURVEILLANCE REQUIREMENTS WAS IN PROGRESS AT SHIFT RELIEF TIME AND THE VERIFICATION OF CORRECT BREAKER ALIGNMENT WAS OVERLOOKED BY THE ONCOMING SHIFT UNTIL APPROXIMATELY SIX HOURS AFTER THE CD'~DIESEL GENERATOR WAS DISCOVERED INOPERABLE. THE CORRECT BREAKER 1- 4 ALIGNMENT WAS THEN IMMEDIATELY VERIFIED ALTHOUGH THE CD DIESEL GENERATOR WAS AVAILABLE AND BEING TESTED AT THIS TIME. THE IMPORTANCE OF ASSURING THAT ALL SPECIFIED SURVEILLANCE REQUIREMENTS ARE COMPLETED HAS BEEN DISCUSSED WITH THE SHIFT INVOLVED.
