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 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 achieve and 88.l 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-g' site power.

D. OPERATOR ACTIONS

1. IF while executing this procedure, the fire is extinguished AND tTe Shift Foreman 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.

Instrument Location 2-CAC-TR-4426-1 Supp'ession Pool Temp. (Pt. 1) Control Room Panel 2-CAC-LR-2602 Torus Level Control Room Panel 2-C32-PI-R605 Reactor Pressure Control Room Panel 2-C32-LI-R606A Reactor Water Level Control Room Panel

3. _IF, reactor building entry is required to restore g monitor equipment, THEN
a. DISPATCH the following minimum canpower for perfonnance of this procedure:
