Content:
the containment enclosure building is constructed of reinforced concrete, it is usually supported on the same mat foundation which supports the containment. Where the containment enclosure building is constructed of structural | steel and metal siding, it may surround only the exposed portion of the containment. In such a situation, the enclosure building columns are founded on individual or combined footings at grade level, on the roof of the buildings adjacent to or surrounding the containment, on the dome of the containment, or possibly on brackets anchored to the exterior face of the cylindrical wall of the containment. General arrangement of such foundations is reviewed with particular emphasis on methods of isolating the enclosure building from other buildings in a lateral direction, where this is preferable to minimize seismic interaction. c. Auxiliary Building Foundation The auxiliary building foundation is typically of a mat type, particularly where the supporting medium is soil. The general arrangement of the foundation is reviewed, with particular emphasis on methods of transferring loads from the structure to the foundation media. d. Other Category I Foundations The foundations for other seismic Category I1 structures, which may be one or a combination of several foundation types, are reviewed to an extent similar to that of the containment foundation. Among seismic Category I structures the foundations of which are so reviewed, are: fuel storage buildings, control buildings, diesel generator buildings, intake structures, and cooling towers. Also reviewed are foundations of safety-related structures which, because of other design provisions, are not classified as seismic Category I. 3.8.5-2 Rev. 1 - July 1981 2.
