'HALON FIRE SUPPRESSION SYSTEM llMITING CONDITION FOR OPERATION 3.7.9.4 The following halon 1301 fire suppression systems shall be OPERABLE with: an intact gas boundary, an operable activation system, and a container having a net weight of not less than 95% of full charge weight at 325 psig minimum (corrected to 70*F).

a) West D.C. Switchgear Room b) East D.C. Switchgear Room APPLICABillTY: At all times.

ACTION:

a, With one or more of the above systems inoperable, establish a conttaucus fire watch with backup fire suppression equipment for the unprotected area (s) within I hour; restore the system to OPERABLE status within 14 days or, in lieu of any other report required by Specification 6.6.1, prepare and submit a Special Report to the Commission, pursuant to Specification 6.9.2, within the next 30 days cutlining the action taken, the cause of the inoperability and the plans and schedule for restoring the ystem to OPERABLE status,

b. The provisions of Specification 3.0.3 are not applicable.

SVRVEILLANCE RE0VIREMENTS 4.7.9.4 Each of the above halon fire suppression systems shall be demonstrated OPERABLE:

a. At least once per 6 months:
1. By performing a system functional test which includes simulated autcmatic operation of the system; and:
a. simulated manual actuation of the system.
b. verifying that the storage containers have a net weight of not less than 95% of full charge weight at 325 psig (corrected to 70*F).
c. verifying the associated room dampers close.
b. At least once per 18 months:
1. By performing a visual inspection of the discharge nozzles to assure no blockage.
2. By performing a visual inspection to assure the gas boundary is intact, l

'3/4.7.10 PENETRATION FIRE BARRIERS LIMITING CONDITIONS FOR OPERATION 3.7.10 All fire rated assemblies (walls, floor / ceilings, cable tray enclosures, and other fire barriers) separating safety-related fire areas or separating portions of redundant systems important to safe shutdown within a fire area and all sealing devices in fire rated assembly penetrations (fire doors, fire windows, fire dampers, cable, piping, and ventilation duct penetration seals) shall be OPERABLE.

APPLICABILITY: At all times unless otherwise determined that the separation of safety-related fire areas or separating portions of redundant systems important to safe shutdown within a fire area is not required based on the MODE of operation.

ACTION:

a. With one or more of the above required fire rated assemblies and/or penetration sealing devices inoperable, within 1 hour:
1. Determine that the fire areas / zones on both sides of the affected fire rated assembly and/or penetration sealing device are monitored by either an OPERABLE fire detection or automatic suppression system at the fire barrier and establish a fire watch patrol that inspects both areas at least once per hour, 2I
2. Establish a continuous fire watch on at least one side of the affected fire rated assembly and/or penetration seal, er
3. Temporarily repair the inoperable fire rated assembly and/or sealing device and classify it as temporary.

All teinporary or inoperable fire rated assemblies and/or sealing devices shall be permanently repaired within 30 days, or implement ACTION 1 or 2 above,

b. The provisions of Specification 3.0.3 are not applicable.

SVRVEI1 LANCE RE0VIREMENTS l

4.7.10 The above required fire rated assemblies and penetration sealing devices shall be verified to be OPERABLE by a visual inspection:

a. At least once per 18 months for fire doors and fire dampers.
