C. ENTRY CO,NDITION 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 Forenan 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-- R B.l 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 of f-site power.

D. OPERATOR ACTIONS

1. IF while exec ting this procedure, the fire is extinguished AND IIIe Shift Foreman determines that no action within this procedure is required EEN EXIT this procedure.
2. OBSERVE the following parameters on instruments indicated while performing actions to achieve and maintain cold shutdown.
