LIMERICK GENERATING STATION

1. AREA DESCRIPTION The area under consideration is the ESW and RHRSW Pump Area on the 268' elevation of the Spray Pond Pump Structure (Fire Area 122A). The bounding walls of.the area are of reinforced concrete construction with an average thickness of 2 ft' . The total surface area for heat transfer is 3860 ft2 (see Attachment A for. sketch and Calculation of surface areas).

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

There are no combustible liquids in this area.

3. VENTILATION PARAMETERS Ventilation to the area is through a doorway located in the West Wall of

~

the area.

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

5. RESULTS The 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.
