- 1 IHIS INSTRUCTION PROVIDES THE STEFS REQUIRED TO RECOVER THE STATION FOLLOWING A "3LACKOUT".

' 1.1 A '3LACKOUT", l.0SS OF POWER TD THE 4KV GROUP 3USSES, WILL RESULT IN A REACTOR TRIP, TURBINE TRIP, AND A LOSS OF STATION POWER TO BOTH UNIT 1 AND UNIT 2. THE 4KV VITAL 3USSES WILL BE AUTOMATICALLY ENERGlZED FRCM THE EMERGENCY DIESEL GENERATORS. THE

~ 4KV GROUP EUSSES CAN BE MANU/LLY ENERGlZED FROM THE GAS IURBINE GENERATOR.

1.2 SINCE A 3LACKOUT WILL RESULT IN A LOSS OF FORCED FLOW THROUGH THE REACTOR, DECAY HEAT WILL BE REMOVED BY NATURAL C:RUCLATION. IHIS INSTRUCTION PROVIDES THE GUIDELINES TO  ;

BE FOLLOWED TO VERIFY NATURAL CIRCULATION.

2) 1 & 2 TURBINE GENERATOR EMERG(NCY BEARING 0!L PUMPS
3) 1 & 2 EMERGENCY SEAL OIL pumas.

3.2 MMUAL 3.2.1 VERIFY THAT A REACTOR TRIP HAS TAKEN PLACE:

I" 1) CHECK THAT ALL FU' . LENGTH RCDS ARE FULLY INSERTED BY CHECKING INDIVI: UAL RCD POSITION INDICATORS AND RCD BOTTCM LIGHTS.

~

B. OPEN 1(2)CV75, RAPID 30 RATION STOP VALVE. -

C. 30 RAT'E FOR AT LEAST 8 MINUTES FOR EACH RCD NOT FULLY INSERTED (4 MINUTES WITH BOTH PUMPS IN FAST).

3.2.2 VERIFY TURBINE TRIP BY CHECKING THE FOLLOWING:

1) UNIT TRIP LIGHT ON E/H CONSOLE ILLUMINATED.
2) TURBINE STOP VALVES, GOVERNOR VALVES, INTERCEPTOR VALVES AND REHEAT STOP VALVES CLOSED.
3) TURBINE $ PEED DECREASING.

IF THE TURBINE HAS NOT TRIPPED, PROCEED AS FOLLOWS UNTIL STEAM FLOW FF..M THE STEAM 6ENERATORS IS TEFMINATED.

4) INITIATE A MANUAL TRIP WITH THE HANDLE ON THE CONSOLE
5) TRIP CLOSED THE MA*N $ TEAM ISCLATION VALVES, 11-14(21-24)MS167 FROM EITHER

'HE SAFEGUARDS BEZE S OR MAIN STEAM BEZELS.

W IF THE UNCONTROLLED STE AM FLOW HAS CAUSED REACTOR COOLANT SYSTEM PRESSURE TO DECREASE To <1755#, INSJRE $AFETY INJECTION IS ACTUATED. IF SAFETY INJECTION IS NOT ACTUATED, INITI ATE IT MANUALLY BY INSERTING THE 3AFEGUARDS KEY INTO EITHER IRAIN "A" OR "3" SAFETY INJECTION OPERATE BEIEL AND TURN THE KEY.

PROCEED TO El I-4.0, "D FETY INJECTION INITIATION".

3.2.3 VERIFY THAT RCS WIDE Rana; TC IS DECREASING TOWARD OR IS BEING MAINTAINED AT 547'F BY ATMOSPHERIC STEAM RELIEF.
