LIMERICK GENERATING STATION

1. AREA DESCRIPTION The area under consideration is the Recombiner Access Area, Room 259, on

-the 200' elevation of the Control Structure (Fire Area IN). Bounding walls are of concrete masonry units and reinforced concrete construction with an average thickness of 2 ft. The south wall of the access area is a non-fire rated barrier. The total surface area for heat transfer is 5456 ft2 (see Attachment A for sketch and surface area calculations.)

2. COMBUSTIBLE LOADING There are no cable tr;ys or combustible liquids located in this area.

3. VENTILATION PARAMETERS Three doors enter the area. On the east wall is a set of double doors with each leaf measuring 5' wide by 8' high. Two doors, each measuring 3' wide by 7' high, are located in the south wall.

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

5. RESULTS The structural steel in this area will not fail since there are no fixed combustibles in the area to support a fire.
