CfCSE SMALL HOLE IN PUS LUCTWORK ON SECONDARY SIDE OF STARTUP TRANSFORMER ALLOWED WATEI, INSIDE THE DUCTWORK. THIS IS BEllEVED TO HAVE CAUSED THE GROUNL FAULT (INVESilGAT10N NOT COMPLETE).
ElfETY SIGNIFICANCE ALTHOUGH OFFSITE POWER REMAINED AVAILABLE TO THE UNIT 2 SWITCHYARD, P0hEi! COULD h01 EE RESTORED TO THE EMERGENCY BUSES FROM 0FFSITE FOR APPROXIi4TELY 10 HCUES. POWER TO THE EMERGENCY BUSES MUST BE-PROVIDED BY THE EMERGENCY DIESEL GENERATORS UNTIL OFFSITE POWER IS RESTORED.
HEUS.SlG c l' NIT 2 WAS CFERATING AT 3CCI POWER; STARTUP TRANSFORMER CROU$D FAULT ALARM WAS RECEIVED IN CONTROL ROOM: OPERATORS INITIATED GRtEUAL POWER LECREASE. UillT 1 IN COLD SHUTDOWN.
o RELAY CREF WAS TROUBLESHOOTING THE CAUSE OF THE ALARM WHEN A SECOND Sil0RT OCLbRRED CAUSING LOSS OF THE STARTUP TRANSFORMER.
(BUS DUCT WAS DAMAGED; FLASH 0VER OCCURRED; WATER IN BUS DUCT.)
o BOTH REclRCULAT10N PUMPS TRIPPED.
o REACTOR WAS MANUALLY SCRAMMED (FROM 73% POWER) TO PREVENT
- lliSTABILITIES/ CORE OSCILLATIONS AS ADDRESSED IN NRC BULLETIN 88-07, o SUDSEGUENT TUI!EINE TRIP ANL MAIN GENERATOR TRIP ".ULLTED IN LOSS OF POWER TC PLANT LOADS FROM THE UNIT AUXILI ARY TRANSFORMER (UAT).

o POWER COULD NOT LE RESTORED TO E3 AND E4 FROM THE UAT BECAUSE ThE INITIAL EDE AUTO START SICNAl (UV RELAY FROM STARTUP TRANSFORMER) COLLL NOT BE CLEARED.
