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

C. ENTRY CONDIT_ ION 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 equipment, AhD
2. The Shift 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 concurrently with E0P's and other operdtions procedures to achieve and maintain Cold Snutdown coincident with or wishout a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> loss of off-sice power. N S.1 D. OPERATOR ACTIONS

1. IF while exscuting this procedure, the fire is extinguished AND Tiie Snift Foreman determines that no action within this procedure is required, THEN EXIT this procedure.

~

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

Instrument Location 2-CAC-TR-778 Suppression Pool Water Temp. (Pt. 7) Remote Shutoown Panel ,

2-CAC-LI-3342 Torus Level Remote Shutdown Panel 2-C32-PI-3332 Reactor Pressure Remote Shutdown Panel 2-B21-LI R604BX Reactor Water Level Remote Shutdown Panel

3. IF reactor building AND/OR diesel generator building entry is Te~ quired to restore Q monitor equipment. THEf4
o. DISPATCH the following minimum manpnwer for performente of this procedure:

4. PLACE Reactor Water Level "NORMAL / LOCAL" switch, 2-B21-CS-3345 at the Remote Shutdown Panel, to the "LOCAL" position to make level indicator 2-B21-LI-R604M operable.
5. IF Diesel Generator operation is required. THEN BLOCK OPEN UTesel Generator Building doors, as indicated on Attachment 1, to establish ventilation for Diesel Generator operations.

l 6. IF RBCCW Heat Exchangers Service Water Inlet Valve, 2-SW-7106 UNNOT be operated f rom the RTGB, THEN Manually 0PERATE 2-SW-V106.

! 7. IF Vital Header Cross-tie Valve, 2-SW-V118 CANN0T be operated TEom the RTGB, THEN Manually 0PERATE 2-SW-V118,

8. IF operation of RHR Service Water System is required AND RHR Te~rvice Water Booster Pumps are NOT available, THEN RUD to OP-43,
