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.
l AND 2.
The Shift Foreman has determined that the reactor is to be brought to Cold ShJtdown using Trt.in A and/or Train B.
The purpose of this proced6re is to provide supplemental actions to be used concurrently with E0P's and other operations procedures to achieve R B.l 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.
D.
OPERATOR ACTIONS 1.
IF while executing this procedure, the fire is extinguished IND the Shift Foreman determines that no action within this procedure is required, THEN EXIT this procedure.
2.
OBSERVE the following parameters or, instruments indicated while performing actions to achieve and me.intain cold shutdown.
Instrument Location 2-CAC-TR-4426-1 Suppression 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-R606 A Reactor Water Level Control Room Panel 2-CAC-T.1-778 Suppression Pool Water Temp. (Pt. 7)
