1. Per 10 CFR 50 Append;x "P." Sections llt.G & L.
2. Per 10 CFR 50 Appendix "R" Section Ill.J.

C. 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 B equipment, AND
2. The Shift Foreman has determined that the reactor is to be brought to Cold Shutdown using Alternative Safe Shutdown Train A.

l The purpose of this procedure is to provide supplemental actions to be used concurrently with E0Ps and other operations procedures to achieve 4nd l R B.I 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-l sita power.

D. OPERATOR ACT10fis

1. IF while executing this procedu're, the fire is extinguished AND tTieShiftForemandeterminesthhtnoactionwithinthis procedure is required, THEN EXIT this procedure.
2. OBSERVE the following parameters on instruments indicated while performing actions to achieve and maintain cold shutdown.

Location Instrument 1 2-CAC-TR-44:6-1 Suppression Pool Temp. (Pt.1) Control Room Panel Ccr.irol Room Panel 2-CAC.LR-2602 Torus Level Control Room Panci 2-C32 PI-R605 Reactor Pressure Control Room Panel 2-C32-L1-R606 A Reactor Water Level

3. IF reactor building entry is required to restore OR,R monitor equipment, THEf(
a. DISPATCH the following minimum manpower for performance of this procedure:

b. OBTAIN the following keys from the Shift Foreman's Key Locker
/

(1) ASSD Equipment Cabinet Key #148 (1) ASSD Flashlight Tool Box Key #160

~ ~~

c. OBTAIN Security Access Keys from SAS Security Officer located in the Control Room

- AND PROCURE the following equipment from the ASSD Tqiiipment Cabinet:

For Reactor Buildh

1) Sound powered phone

~((1) Flashlight (1) Copy of this procedure (3) Remote Shutdown Keys, Serial T112

_ (1) Security Access Key (1) Twenty-five foot sound powered phone extension cord

d. USE appropriate figures in this procedure to provide access / egress routes, equipinent and comunication'"

locations.

NOTE

! Implementation of ASSD-18 for Unit 1 l

will requjre Diesel Generator No. 4 to be crons-tied to 4KV Bus El via 1 4KV Bus EU. When 4KV Bus El and

. Substation E5 are re-energized by Unit 1, Suppression Pool Cooling and Shutdown Cooling for Unit 2 can then be established using Train A safe shutdown equipment.

4. IF Nuclear Service Water to Vital .eaoer Valve, 2-SW-V117 UNNOT be operated from the RTG8, THEN Manually OPERATE F5V-T117.
5. IF Nuclear Service Water Supply Valve, 2-SW-V105 CANNOT be operated from the RTGB, THEN Manually OPERATE 2-SVWfDT.
6. IF Conventional-Nuclear Header Cross-tie Valve, 2-SW-V102 UNNOT be operated from the RTGB, ~THEN Manually OPERATE F5W-7102. j
7. IF operation of RHR; Service Water System is required AND RHR Tervice Water Booster Pumps are jiOT, T available, THEN RUER to 09-43.
