s;Page 240ga74 - FDL PSAPS 3.14 BASES l The water and CO2 Fire Protection Systems provide fire suppression l
capabilities in those areas of the plant wnere orotection of plarit equipment is 4
deemed necessary.
r f
A.
Water Fire Protection SystCO i
Two fire pumps supply water to sprinklers, manual hose s',ations, and hyirants in or turroundirg the plant. One electrically driven pump is poaered 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 fira, mp bect me Inoperable, LrneJ14te corrective l
measures are taken since this syf te is a major porthn of the fire suppression i
capability of the plant.
Re requirement fot a twenty four hour report to the Comission provides for prompt evalua: 1on of the acceptability of the corrective measures to provide adequate fire sunpression capability for the continued
.I protection of the plant, i
i B.
C09 Fire Protection Systems i
The CO2 Fire Protection Systems previod fire suppression capability for the i
Cable 5preadir.g Room, Computer Room, Control Room, HPC' Rooms, and the Diesel Generator Rooms.
The specified minimum cuantities of i.02 provide the
]
Capability to flood the Cable Spreading Rono and Computer Room simultaneously, a HPCI rocm, or a Diesel Generator Room with sufficient CO2 to meet 3
J concentration objectives.
In the event that portions of the C0; Fire Protection $ystem are inoparable.
I alternate backup fire fighting equipment is required to be marJe nailable in the j
af fected areas until the affected fire suppression equipment can be returned to
)
service.
f i
1 C.
Fire Dete: tion t
1 Operability of the fire detectors ensures that adequate warning is available for I
the P W Dt detection of fires.
This capability is required in order to detect l
and Ic. ate fires in their early stages, prompt detection of fires will reduce j
the potential for damage to plant equirent and is an integral element in the overall plant fire protection program.
Table 3.14.C.1 specifies the minimum 1
j reber of operable detectors in each room.
l There are sixteen heat detectors in each diesel generator rcom, two detector s I
]
located in close proximity to each other at each of eight locations (each j
constituting a "zone"). Actuation of both detectors in any zone will initiate i
Cardox cischarge in tne room and a trip signal to the diesel generator in the 1
room. Cne detector or bcth detec. ors in one zone of each diesel generator room I
fray be inoperatie for a period not to esteed seven days without co?pensatory
]
measures being taken.
