PVNGS FSAR APPENDIX 9A Building (refer to figure 9B-9,[formerly FPER Figure 2], column lines J4/JD). This hose will be able to reach Zones 21A, 21B, 22A and 22B (formerly Zones 21 and 22). Installation will be completed prior to fuel load.

b. Zones 74A and 74B formerl Zone 74 Main Steam Support Structure (MSSS) Zones 74A and 74B (formerly Zone 74) can be reached throughout.

the 100 foot (grade) elevation and 140 foot level from standpipe and hose stations at those levels located at the northwest corner of the Turbine Building. These hose reels will be equipped with 150 feet of 1-1/2 inch hose from hose station 563 (100 foot elevation) and 100 feet of 1-1/2 inch hose from hose station N72 (140 foot elevation).

0 The 120 foot elevation of the MSSS is an open grating and hose streams can be directed at all areas of that level upward from the 100 foot eleva-tion and downward from the 140 foot, elevation (which is also an open grating. The hose nozzles will reach within 30 feet of all areas of the building.

C. Zones 37C and 37D formerl Zone 37 All areas of the Auxiliary Building Zones 37C and 37D (formerly Zone 37), can be reached within 30 feet. by 125 feet of l-l/2 inch hose from hose station 525.

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
