C. ENTRY CONDITION This procedure is entered from Alternative Safe Shutdown Index A550-01.

1. A fire has occurred in an area centaining Alternative Safe Shutdown Train B equipment, AND
2. The Shift Foreman has determined that the reactor is to be brought to Cold Shutdown using Alternative Safe Shutdown Train A.

The purpose of this procedure is to provide supplemental actions to be used concurrently with E0Ps and other operations procedures to achiev,e and 80.1 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 of 6 site power.

D. OPERATORACT!_03 IF while executing this procedure, the fire is extinguished AND l ~~ ll 1. Shift Foreman determines that no action within this Ec procedure is required,,THR Exli this procedure.

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