PEACH BOTTOM GENERATING STATION 1.
AREA _QEggRIPTIgN The area under consideration is the Health Physics Utility Room on the 116'-O" elevation of the Turbine Building (Fire Area 82).
The bounding walla are constructed of reinforced concrete with an average thickness of 1 ft.
The total surface area for heat transfer is 904 ft2 (see Attachment A for a sketch of the area under consideration).
