UESTION 9A.116 (FPER Audit Open Item No. 11)
(9B.3)
The applicant, in the Fire Protection Evaluation committed to comply with Section E.l of BTP ASB 9.5-1 concerning the design and installation of fire detection systems.
We observed that Amendment l3 9A-98 August 1984
PVNGS FSAR APPENDIX 9A fire detectors were absent from the following areas which contain safety related equipment.
a.
Condensate transfer pump room (Zone 83) b.
Elevation 131 feet, Diesel Generator Building (Zones 25A and 25B [formerly Zone 25])
c.
Above auxiliary control cabinets (Control Room) d.
In computer room adjacent. to the control room, within the control room complex e.
(DELETED) f.
"Dead air space" such as in Zones 37C and 37D (formerly Zone 37) (Elevation 70 feet, Auxiliary Building) g.
E.C.W.
heat, exchanger rooms (Zone 43) h.
Charging pump rooms (Zones 46A, 46B and 46C [formerly Zone 46])
i.
Spray chemical accumulator room j.
Spray chemical storage tank zoom (Zone 51B)
RESPONSE
The area listed as "g" contains no safety related equipment. susceptible to fire damage.
The only safety-related component within Zone 43 is the essential cooling water heat exchanger (i.e., the heat exchanger shell).
No significant combustible loading is present.
Therefore, no detectors are required.
Area "d," the computer room adjacent to the control room, has fire detectors to detect fire and activate the Halon suppression system.
Potential dead air spaces between heavy beam ceiling supports have been previously identified and reviewed (through site walkdowns) by the detector supplier.
Additional detectors were added based on air flow and configuration.
The remaining "dead air spaces,"
noted as August 1984 9A-99 Amendment l3
