ENGI!1EERI!1G ASSESSMENT BATTERY ROOM CORRIDOR FULL AREA SUPPRESSION CAPABILITY 1.O PJJTQSX The purpose of this assessment is to address the adequacy of existing fire protection capabilities in Fire Zone BR-5 when analyzed against the critoria of Appendix R Section III.G.3.

James A.
FitzPatrick Nuclear Power Plant Evaluation of the Compliance tc Appendix R section III,G. October 1985.
3.o DAQEGB9X1fD 3.1 Annlicable Rectylatory Criteria Appendix R Section III.C.3 requires that detection and fixed suppression be provided in areas,
- rooms, or zones for which alternate shutdown capability is provided.
Redundant cables for safe shutdown systems are located in the Battery Room Corridor Fire Zone DR-5.
Fire Zone BR-5 has been redefined as Fire Area XVI and is the only zone within the area.
Alternative shutdown capability is required for this area due to loss of Division "A"
and "B"
cabling due to a fire in the area.
Modifications previously implemented in Fire Zone DR-4 to ensure alternative shutdown for a fire in the Main Control Room also ensure alternative shutdown for a fire in Fire Zone BR-5 via the provision for Division "B"
de power to the remote shutdown panels via distribution panel 71DC-B4 (Fire Zone EG-6).
Automatic detection is provided for the Battery Room Corridor; however, suppression system capability is not.
4.O ANAL]L81H 4.1 Combustible.MatqEini The Battery Room Corridor has a combustible loading consisting of cable insulation, with an equivalent fire severity of under one hour.
The Battery Room Corridor provides access only to the Battery and Battery Charger Rooms; it is not a normal access route to other plant locations.
The introduction of transient combustible materials into the corridor, other than that required for work in the corridor and adjacent Battery and Battery Charger Rooms is considered to be highly unlikely.
Therefore, the cable insulation is the primary source of combustible material in this area.

4.2 Detection and Suppression Automatic detection consisting of ceiling mounted ionization detectors is provided in the corridor.
Potential fires in the Corridor would involve primarily cable insulation Battery Roon located in trays near ceiling lovel or in vertical risors along the south wall.
Fires of this naturo would be detected in the incipient stage, with alarm notification in the continuously manned Main Control Room.
Alarm notification would result in prompt dispatch of the fire brigade for rapid initiation of manual fire fighting activitics.
4.3 Other Features Portable extinguishers and a manual hose station are provided in the Battery Room corridor.
Extinguishers and hose stations are also available for fire brigado uso in adjacent locations.
Reasonable assurance is provided that manual fire fighting activities would result in prompt extinguishment of postulated fires.
5.0 CQNCLUSION Based on the results of the proceding assessment, the provision of suppression in the Battery Room Corridor would not significantly The basis for this improve the existing fire protection features.
l conclusion are summarized as follows:
Alternative shutdown capability is provided outsido of the area Automatic detection adequato for the hazards is provided at ceiling level Postulated cable insulation fire scenarios would bo detected in the incipient stage, alarmed in the Main Control Room and result in prompt dispatch of the fire brigado.
Manual fire fighting activities using extinguishers and hose stations available in the zone and in adjacent locations wo'nd result in prompt extinguishment of postulated fires.
