1. Per 10CFR50 Appendix 'R' Sections !!!.G & L.
2. Per ICCfR50 Appendix 'R' Section !!!.J.

C. ENTRY CONDITION This procedure is entered from Alternative Safe Shutdown Index ASS 0-01.

__ 1. A fire has occurred in an area containing Alternat'Ne Safe Shutdown Train B equipment, AND

2. The Shif t Foreman has determined that the reactor is to be brought to Cold Shutdown using Alternative Safe Snutdown Train A.

The purpose of this procedure is to provide supplemental actions to be used concurrently with E0Ps and other operations procedures to achievp 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. g g,g

0. OPERATOR ACTIONS  !
1. IF while executing this procedure, the fire is extinguished AND the Shift Foreman determines that no ac' ion within this .

procedure is required, THEN EXIT tnis procedure.

2. OBSERVE the following parameters on instruments indicated while performing actions to achieve and maintain cold shutdown.
