C. ENTRY CONDITION This procedure is entered from Alternative Safe Shutdown Index ASSD-01. I

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

AM)

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 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 /tp, l off-site power.
