1. Per 10CFR50 Appendix 'R' sections III.G & L.

2. Per 10CFR50 Appendix 'R' sections 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 and Train B equipment, AND

2. The Shift Foreman has determined that the reactor is to be brought to Cold Shutdown using Train A and/or Train B.

The purpose of this procedure is to provide supplemental actions to be used concurrently with ECP'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 R g,l off-site power. i h) D. OPERATOR ACTIONS

1. IF while etect, ting this procedure, the fire is extinguished AND j tTe Shift Foreman determines that no action within this l procedure is required, THEN EXIV thi:. procedure. l

2. OBSERVE the following parameters on instruments indicated while perfor:ning actions to achieve and maintain cold shutdown. ,

Instrument Location l 1-CAC-TR-4426-1 Suppression Pool Temp.
