PEACH BOTTOM JENERATING STATION 1.
AREA _DgggRIPTIgN The area under consideration is the Clean Clothes Room on the 116'-O" elevation of the Turbine Building (Fire Area 11j).
The bounding walla are constructed of reinforced concrete with an average thickness of 1 ft.
The total surface area for heat transfer la 1,044 ft2 (see Attachment A for a sketch of the area under consideration).

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