2. Per 10CFR50 Appendix 'R' Section Ill.J.

C. ENTRY _CONDIT!0f(

This procedure is entered from Alternative Safe Shutdown Index ASSD-01,

1. A fire has occurred in an area containing Alternative Safe Shutdown Train B equipment,

.A3

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 achiev'e'ind RB.I 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 j 1. IF while executing this procedure, the fire is extinguished AND

, the 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 ,
