- 1. Per 10CFRS0 Appendix 'R' Sections III.G & L.
- 2. Per 10CFR50 Appendix 'R' Section !!!.J.
C. ENTRY C0!40!T!0?4 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 equipacnt, Af4D
- 2. The Shift Forenan has determined that the reactor is to be brought to Cold Shutdown using Alternative Safe Shutdown Train B.
Tne purpose of this procedure is to provide supplemental actions to be used concurrently with E0P's and other operations procedures to achieve, ,
and maintain Cold Shutdown coincident with or without a 72 nour loss of off-site power. K 15..L D. OPERATOR ACTIONS
- 1. IF while executing this procedure, the fire is extinguished AND tiie Snitt Foremen determines that no action within this procedure is required. THEN Exli this procedure.
- 2. OBSERVE the following parameters on instruments indicated while performing actions to achieve and maintain cold shutdown.
Instrument location 2-CAC-TR-778 Suppression Pool Water Temperature Remote Shutdown Panel 2-CAC-L1-3342 Torus Level Remote Snutdown Panel 2-C32-PI-3332 Reactor Pressure Remote Shutdown Panel 2-B21-L1-R604BX Reactor Water Level Remote Shutdown Ponel
