PBAPS 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.

A. Water Fire Protection System Two fire pumps supply water to sprinklers, manual hose s^ations, 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 The CO2 Fire Protection Systems provide fire suppression capability for the Cable Spreading Room, Computer Room, Control Room, HPCI Rooms, and the Diesel Generator Rooms. The specified minimum quantities of CO2 provide the capability to flood the Cable Spreading Room, Computer Room, a HPCI room, or a Diesel Generator Room with sufficient CO2 to meet concentration objectives.

In the event that portions of the CO2 Pire 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.

C. Fire Detection Operability of the fire detectors ensures that adequate warning is available for the prompt detection of fires. This capability is required in order to detect and locate fires in their early 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.

- 240 q-

PBAPS In the event that a portion of the fire detection instrumentation is inoperable, the establishment of fire patrols in the eccessible affected areas is required to provide detection capability until the inoperable instrumentation is returned to service.

D. Fire Barrier Penetrations The functional integrity of the fire barrier penetration seal 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 extinguishment. 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 of the affected seal until the seal is restored to functional status.

E. Water Suppression System Water suppression systems for the oil systems located within the M-G set room and M-G set lube oil room are provided to contain a possible oil fire to the respective fire area. The_ suppression system is a pre-action type using smoke detectors to charge the sprinkler headers with fire water and spray nozzle actuation on high temperature. Both fire water ficw (Iow pipe pressure swi tch ) and smoke detector actuation annunciates in the control room. The sprinkler header is normally pressurized with air, with a low pressure annunciator to monitor header and nozzle integrity.

F. Battery Room Ventilation Flow Detector Loss of the battery room exhaust ventilation flow will result in a buildup of combustible gases and a potential fire hazard to i

safety-related cables. A flow detector will annunciate an alarm in the control room upon poor ventilation conditions.

PBAPS 4.14 BASES A. Water Fire Protection System The monthly test of the fire pumps is conducted to check for equipment failures and deterioration. The fire pump minimum capacity is based on a design load of 2400 gpm for the largest oprinkler plus 300 gpm for manual hose lines.

When it is determined that a fire pump is inoperable, the increased surveillance required by 4.14.A.2 provides adequate assurance that the remaining pump will be operable when required.

B. CO2 Fire Protection Systems Weekly checking of the storage tank level and pressure is deemed adequate to provide assurance that sufficient CO2 will be available in the event of a fire occurrence.

The method for testing heat detectors in the automatic discharge systems is in accordance with NFPA-72E-1974.

Testing of the discharge initiation logic, injection valve, damper closings, and fan trippings without actual discharge of CO2 into a room demonstrates operability of the active components of the systems. System operability is demonstrated by both manual and automatic initiation for automatic discharge systems.

Testing of the headers and nozzle by an air flow test will detect buildups of material which may affect continued availability.

C. Fire Detection The method for testing fire detectors is in accordance with NFPA-72E,1974.

D. Fire Barrier Penetrations Penetration fire barrier seals are visually inspected to verify that they are functional.
