3011 BASES '
E11L' PROTECTION SYSTEMS The OPERABILITY of the fire protection systems ensures that adequate fire protection features are available to detect, confine, and extinguish fires occurring in any portion of the facility where safety-related equipment is located. The fire protection system J
consists of fire detection instrumentation, fire pumps, and water i
distribution mains, spray and/or sprinkler systems, CO2 F" tJms, fire I
hose stations, yard fire hydrants and hose house stations.nd fire barriers. The collective capability of the fire suppression systems is adequate to minimite potential damage to safety-related equipment and is a major element in the facility fire protection program.
OPERABILITY of the detection instrumentation ensures that both adequate warning
[
capability is available for prompt detection of fires and that fire suppression systems that are actuated by fire detectors will discharge extinguishing agent in a t " "v manner.
Prompt detection and i
suppression of fires will i the potential for damage to an integral element in the overall safety-related equipment &
4 facility fire protection pt.
am.
In the event that portions of the fire protection systems are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas until the inoperable equipment is restored to service. When the inoperable fire fighting equipment is l
intended for use as a backup means of fire suppression, a longer period of time is allowed to provide an alternate means of fire fighting than if the inoperable equipment is the primary means of fire suppression.
If in the avent that all the high-pressure fire pumps become inoperable, an alternate backup pump or supply is available, such as using the additional fire pump which normally protects outlying areas and mobile fire apparatus to maintsin the 2250 gpm water supply at a system head of 300 feet.
Fire protection water systems protecting areas containing redundant safe shutdown systems, as defined in BFN's Fire Hazard Analysis, warrant more stringent compensatory measures (i.e., continuous fire watches) than l
areas containing only one division of safe shutdown systems or safety-related equipment not required for safe shutdown under fire l
conditions.
l The surveillance requirements provide assurances that the minimum OPERABILITY requirements of the fire protection systems are met. All fire protection equipment surveillances required by this technical specification can be performed when the unit is in any operating mode.

Flushing of the high-pressure' fire protection system mains and building headers assures that sediment and marine growth is removed from the system to prevent obstruction.
Subsequent biocide addition reduces further marine organism growth.
Individual hose stations and fire hydrants are not included in the overall flush requirements, but are flushed periodically during specific OPERABILITY verifications.
!!ydraulic performance of the water fire suppression syatem is tested in accordance with the 16th Edition of the Fire Protection Ilandbook, published by the National Fire Protection Association.
The functional integrity of the fire barrier assemblies and penetration sealing devices ensures that fires vill be confined or adequately retarded from spreading to adjacent portions of the facility.
This design feature minimizes the possibility of a single fire from involving several areas of the facility prior to detection and extinguishment.
The fire barrier penetrations are a passive element in the facility fire protection program and are subject to periodic inspections.
The barrier penetrations, including fire doors, fire dampers, and cable and pipe penetration seals, are considered functional when the visually observed condition ~ indicates no significant degradation.
