PEACH BOTTOM GENERATING STATION 1- eBE6_DE29BIEII9N The area under consideration is the Toilet Area on the 116'-O" elevation of the Turbine Building (Fire Area 115). The bounding walls are constructed of reinforced concrete with an average thickness of 1 ft. The total surface area for heat transfer la 1661 ft2 (see Attachment A for a sketch of the area under consideration).

No general room fire was postulated because of the lack of

-exposed fixed combustibles in the area.

There are no cable-trays in this area to present a localized heating exposure to the structural steel.

This area contains no exposed fixed combustiblea. The table below lists the maximum heat release rate for transient

- combustibles for different fire durations which result in an area
