PURPOSE - This procedure provides actions to use engineered safeguards systems to recover plant conditions following restoration of AC emergency power.

B.

ENTRY CONDITIONS / SYMPTOMS 1.

ENTRY CONDITIONS - This procedure is entered from:

l a.

ECA-0.0, LOSS OF ALL AC POWER, when AC emergency l

power is restored and SI is required.

l b.

ECA-0.1, LOSS OF ALL AC POWER RECOVERY WITHOUT SI REQUIRED, if SI is required.

a. Start all SI pumps
a. Perform the following:
1) Start available SI pumps.
2) H SI pump A or B M available. THEN verify SI pump C aligned as follows:

o H SI pump A M available. THEN ensure MOV-871B closed, o H SI pump B M available. THEN ensure MOV-871A closed,

b. Check RCS pressure:
b. Manually start both RHR pumps and go to Step Sd.

o Pressure - GREATER THAN 250 psig [465 psig adverse CNMT) o Pressure - STABLE OR INCREASING

c. Place RHR pump switches in AUTO
d. Start all available CNMT RECIRC fans

CAUTION o IF CST LEVEL DECREASES TO LESS TRAN 5 FEET. THEN ALTERNATE WATER SOURCES FOR AFW PUMPS WILL BE NECESSARY (REFER TO ER-AFW.I. ALTERNATE WATER SUPPLY TO AFW PUMPS).

I IF S/G NR LEVEL DECREASES TO LESS THAN 5% [25% ADVERSE CNMT] AND FEED FLOW o

IS LESS THAN 200 GPM, THEN THE MDAFW PUMPS SHOULD BE MANUALLY LOADED ON AC EMERGENCY BUS TO SUPPLY WATER TO THE S/G(S).

4 If MDAFW pump operation is not required, pump switches should be NOTE: o maintained in PULL-STOP to prevent automatic start.

TDAFW pump flow control valves fail open on loss of IA.

  • 6 Monitor Intact S/G Levels:

fx i()

a. Narrow range level - GREATER
a. Maintain total feed flow greater THAN 5% [25% adverse CNMT]

than 200 gpm until narrow range level greater than 5% [25%

adverse CNMT] in at least one S/G.

IE feed flow less than 200 gpm, THEN perform the following:

1) Verify MDAFW pump discharge valve to intact S/G(s) open.

. S/G A, MOV-4007 S/G B, MOV-4008 e

2) Manually start MDAFW pumps as necessary (228 KW).
b. Control feed flow to maintain narrow range level between 17%
