1. Per 10CFR50 Appendix 'R' Sections III.G & L.
2. Per 10CFR50 Appendix 'R' Section III.J.

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, Am
2. The Shift Foreman has detennined 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 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 g off-site power. R S.J D. OPERATOR ACTIONS

1. IFwhileexecutingthisprocedure,thefireis'$xtinguishedAND tee Shift Foreman detennines that no action wit 11n this procedure is required, THEN EXIT this procedure.
2. OBSERVE the follwing parameters on instruments indicated while performing actions to achieve and maintain cold shutdown.

Instrument Location 2-CAC-TR-778 Suppression Pool Water Temp. (Pt. 7) Remote Shutdown Panel 2-CAC-L1-3342 Torus Level Remote Shutdown Panel
