B.

Carbon Dioxide Systems B.1 The following CO2 Systems shall be Operable with the minimum number of bottles of CO2 indicated, connected and available for service and having at least 90% of full charge weight, whenever the protected equipment in the area is required to be Operable:

a)

Cable Vault (18) b)

Primary Auxiliary Building Charcoal Filters (8)

B.2 From and af ter the time a CO2 system listed in B.1 is determined to be inoperable, within one hour establish a continuous fire watch with backup fire suppression equipment for the unprotected equipment and/or area.

B.3 Restore the system to Operable status within 14 days or prepare and submit a Licensee Event Report to the Commission pursuant to Specification 6.9.2.b within 30 days of the occurrence outlining the cause of the inoperability and the plans for restoring the system to Operable status.

C.

Halon 1301 Systems C.1 The following Halon 1301 Systems shall be Operable with the minimum number of bottles of Halon 1301 indicated, connected and available for service and having at least 92% of full charge weight, whenever the protected equipment in the area is required to be Operable:

a)

Switchgear Room (7) b)

Control Room (3)

C.2 From and after the time a Halon 1301 system listed in C.1 is determined to be inoperable, within one hour establish a continuous fire watch with backup fire suppression equipment for the unprotected equipment and/or area.

C.3 Restore the system to Operable status within 14 days'or prepare and submit a Licensee Event Report to the Commission pursuant to Specification 6.9.2.b within 30 days of the occurrence outlining the cause of the inoperability and the plans for restoring the system to Operable status.

D.

Fire Water Stations D.1 The Fire Water Stations listed in Table 3.22-1 shall be Operable.

3-42

l b)

At least once per 18 months 2 25% by:

i 1.

Verifying that all system components operate properly when mariual devices are manually operated and automatic devices are actuated by a simulated signal, and 2.

Verifying that there is no blockage in headers and nozzles by conducting a flow test.

i C.

Halon 1301 Systems C.1 The Halon 1301 Systems listed in Section 3.22.C.1 shall be demonstrated operable:

8 a)

At least once per six months i 25% the weight and pressure of refillable containers shall be checked. If a container shows a net weight of less than 92 percent or shows a pressure less than 324 psig, it shall be refilled or replaced.

b)

At least once per 18 months 1 25% by:

1.

Verifying that all system components operate properly when manual devices are manually operated and automatic 3

l devices are actuated by a simulated signal, and 2.

Assuring that there is no blockage in discharge piping and nozzles by conducting a visual inspection.

D.

Fire Hose Stations and Hydrants D.1 Each Fire Hose Station and Hydrant listed in Table 3.22-1 shall be verified to be operable:

a)

At least once per month 1 25% by visual inspection of the hose stations and hydrants to assure all equipment is available.

b)

At least once per 18 months 2 25% by removing the hose for inspection and reracking, and replacing all gaskets in the couplings that are degraded.

c)

At least once every year by opening valve and flushing hydrant to verify valve operability and no blockage, d)

At least once per 3 years i 25%, partially open hose station valves to verify valve operability and no blockage.

e)

At least once per 3 years 1 25%, conduct a hose hydrostatic test at a pressure at least 50 psig greater than the maximum 4

pressure available at that hose station.
