C. ENTRY CONDITION This procedure is entered from Alternative Safe Shutdown Index ASSD-01.

1. A fire has occurred in an area containing Alternative Safe Shutdown Train A equipment.

AND

2. The Shift Foreman has determined that the reactor is to be brought to Cold shutdown using Alternative Safe Shutdown Train B.

The purpose of this procedure is to provide supplemental actions to be used concurrently with E0Ps and other operations procedures to achieve- 88.l and maintain Cold Shutdown coincident with or without a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> loss of off-site power.

D. OPERATOR ACTIONS

1. IF rhile executing this procedure, the fire is extinguished IsD the Shift Foreman determines that no action within this

~ procedure is required, EEN EXIT this procedure.

2. OBSERVE the following parameters on instrunents indicated while performing actions to achieve and maintain cold shutdown.

Instrunent location 1-CAC-TR-778 Suppression Pool Water Temp. (Pt. 7) Remote Shutdown Panel 1-CAC-L1-3342 Torus Level Renote Shutdown Panel 1-C32-PI-3332 Reactor Pressure Renote Shutdown Panel 1-B21-LI R604BX Reactor Water Level Remote Shutdown Panel

3. IF reactor building AhD/0R_ dies)) generator building entry is Tequired to restore 01 ronitor equipment. THEf,
a. DISPATCH the following minimum manpower for performance of this procedure:
