PBdPS 3.14 BASES The water and CO2 Fire Protection Systems, although not classified as safety related systems, provide fire suppression capabilities in those areas of the plant where protection of plant equipment is deemed necessary.
t A.
Water Fire Protection System Two fire pumps supply water to sprinklers, manual hose stations, and hydrants in or surrounding the plant.
One electrically driven pump is powered from an emergency power bus; the other pump is diesel driven.
The capacity of each pump is in excess of the system design load.
In the event that both fire pumps become inoperable, immediate corrective measures are taken since this system is a major portion of the fire suppression capability of the plant.
The requirement for a twenty-four hour report to the Commission provides for prompt evaluation of the acceptability of the corrective measures to provide adequate fire suppression capability for the continued protection of the plant.
B.
CO2 Fire Protection Systems i
The CO2 Fire Protection Systems provide fire suppression capability for the Cable Spreading Room, Computer Room, HPCI
{
l' Rooms, and the Diesel Generator Rooms.
The specified minimum i
quantities of CO2 provide the capability to flood the Cable Spreading Room and Computer Room simultaneously, a HPCI room, or a Diesel Generator Room with sufficient CO2 to meet concentration i
objectives.
In the event that portions of the CO2 Fire Protection System are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas until the affected fire suppression equipment can be returned to service.
l l
C.
Fire Detection J
operability of the fire detectors ensures that adequate warning is available for the proinpt detection of fires.
This capability is required in order to detect and locate fires in thei.r early l
stages.
Prompt detection of fires will reduce the potential for damage to plant equipment and is an integral element in the overall plant fire protection program.
