ENTRY CNDITION This procedure is entered from Alternative Safe Shutdown Index AS50-01.

1.

A fire has occurred in an area containing Alternative Safe Shutdown Train A equipment, AND 2.

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

The purpose of this procedure is to provide supplemental actions to be used concur, ently with E0P'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 oT-~

of f-site power.

OPERATOR ACTIONS 1.

IF while executing this procedure, the fire is extinguished AND 17ie Shif t Foreman determines that no action within this procedure is required THEN EXIT this procedure.

2.

OBSERVE the following parameters on instruments indicated while performing act f ans to achieve and maintain cold shutdown.

Instrument location 2-CAC-TR-7/8 Suppression Pool Water Temperature Remote Shutdown Panel 2-CAC-Lt-3342 Torus Level Remote Shutdown Panel 2 CAC-PI-3332 Reactor Pressure Remote Shutdown Panel 2-B21-L1-R604BX Reactor Water Level Remote Shutdown Panel 3.

,l_F reactor building entry is required to restore _0R monitor equipment THEN a.

DISPATCH the following minimum manpower for performance of this procedure:
