1. AREA DESCRIPTION The area under consideration is the ESW and RHRSW Pipeway on the 251' ele-vation of the Spray Pond Pump Structure (Fire Area 122C). The Dounding walls of the' area are of reinforced concrete construction with an average thickness of 2 ft. The total surface area for heat transfer is 2372 ft2 (see Attachment A for sketch and calculation of surface areas).

2. COMBUSTIBLE LOADING All cabling in this area is routed in conduit, thcre are no cable trays.

There are ne combustible liquids in this area.

3. VENTILATION PARAMETERS Ventilation to the area is through a hatch located in the Southwest corner

'of the area and is open to the 268' elevation.

4. CASES EXAMINED With no exposed combustible cabling and no combustible liquids in the area, there is no fuel in the area to support a fire.

5. .RESULTS Tne structural steel in this area will not fail due to a fire as there are no fixed combustibles in the-area to support a fire.
