1. Per 10CFR50 Appendix 'R' Sections 111.G & L.
2. Per 10CFRSO Appe> dix ' R' Section !!!.J.

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 A equipment, AND
2. The Shif t 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 R E5.1 used concurrently with E0P's 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 off-site power.

D. OPERATOR ACTIONS

1. IF while executing this procedure, the fire is extinguished AND tWe Shift Foreaan determines that no action within this procedure is required. THEN EXIT this procedure.
2. OBSERVE the following parameters on instruments indicated while performing actions to achieve and maintain cold shutdown.
