C. ENTRY CONDITION This procedure is entered from Alternative Safe Shutdown Index AS50-01.

1. A fire has occurred in an area containing Alternative Safe Shutdown Train B equipment, AND
2. The Shif t 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 achieve 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 dff' site power. /t S.J D. OPERAf0R ACTIONS

1. IF while executing this proceddre, the fire is extinguishad AND ne 5hift Foreman determines that no action within this procedure is requirad, THEN EXIT tnis procedure.

2, OBSERVE the following parameters on instruments indicated while performing actions to achieve and maintain cold shutdcwn.
