A. TITLE - Emergency Depressurization Procedure B. ENTRY CONDITIONS

1. Depressurization of the reactor is required AND
2. Less than three SRVs can be opened AND
3. Reactor pressure is at least 50 psig above suppression chamber pressure.

C. OPERATOR ACTIONS

                                                            • a***e*******************************************

CAUTION DO NOT DEPRESSURIZE below 120 psig L'NLESS motor driven pumps sufficient to maintain reactor vessel level are running and available for injection.

I

1. DEPRESSURIZE the reactor with one or more of the following systemst
a. Main Condenser
b. Main Steam Line Drains
c. HPCI (full flow test mode)
d. RCIC (full flow test mode)
2. IF the MSIVs are closed due to a reactor vessel lov level Group 1 isolation AND the main condenser is available as a heat sink.

THEN PERFORM the following steps:

a. PLACE all MSIV switches to "CLOSE."
b. PLACE the following switches to "0VERRIDE RESETt" (1) DIV I NON-INTRPT. RNA-SV-5262

_ (2) DIV II NON-INTRPT. RNA-TV-5261 i c. CLOSE the followit.g valves:
