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).
