Amendment No. AM,111 3-87a

3.18.3 Deluge / Sprinkler Systems Applicability: At all times when equipment in the area is required to be operable.

Objective: To assure adequate fire suppression capability.

Specification:

3.18.3.1 The Deluge and/or Sprinkler Systems located in the following areas shall be operable or action shall be taken as described in specification 3.18.3.2.

a. Diesel Generator and Radiator Rooms

b. Diesel Generator Combustion Air Intakes

c. Diesel Generator Cooling Air Intake

d. Control Building Filter (AH-F3A, AH-F38) Rooms

e. Air Intake Tunnel (3 zones)

f. Charcoal Filter (AH-F10, AH-F11) 9 Intake Screen Pump House

h. Diesel driven fire pump areas

1. Control Building at elevation 306'

j. Control Building ESAS Relay Room at elevation 338'6" (manual system)

k. Fuel Handling Butiding at elevation 281'0"

1. Auxiliary Building containment penetration area at elevation 281'0" (automatic preaction sprinkler system) and water curtain at elevation 305'0" 3.18.3.2 With any of the above deluge and/or sprinkler systems in any room or zone inoperable:

a. Establish a continuous fire watch with backup fire suppression equipment for the unprotected area (s), within one hour except that no fire watch is required in the air intake tunnel,

b. Restore the system to OPERABLE status within 14 days or, prepare and submit a Special Report to the Commission within the next 30 days outlining the actions taken, the cause of inoperability and the plans and schedules for restoring the system to OPERABLE status.

3-89 Amendment No. M,101

3.18.7 FIRE BARRIER PENETRATIONS Applicability: All fire barrier penetration seals (including cable and pipe penetration barriers, fire doors and fire dampers) in fire zone boundaries l protecting safety related areas shall be functional at all times when equipment on either side of the barrier is required to be operable.

Objective: To assure the effectiveness of barriers.

Specifications:

3.18.7.1 All fire barrier penetration seals protecting safety related areas shall be functional or action shall be taken as described in 3.18.7.2.

3.18.7.2a With one or more of the above required fire barrier penetration seals non-functional, establish a continuous fire watch on at least one side of the affected penetration within one hour.

3.18.7.2b Restore the penetration seal to an OPERABLE status within 14 days or, prepare and submit a Special Report to the Commission within the next 30 days outlining the action to be taken, the cause of the inoperability and the plans and schedule for restoring the system to an OPERABLE status.

BASES: The functional integrity of the fire barrier penetration seals ensures that fires will be confined or adequately retarded from spreading to adjacent portions of the facility. This design feature minimizes the possibility of a single fire rapidly involving several areas of the facility prior to detection and exti nguishment. The fire barrier penetration seals are a passive element in the facility fire protection program and are subject to periodic inspections.

During periods of time when the seals are not functional, a continuous fire watch is required to be maintained in the vicinity l of the affected seal until the seal is restored to functional status as described in specification 3.18.7.2.
