en this is preferable to minimize seismic interaction. C. Auxiliary Building Foundation The auxiliary building foundation is typically of a mat type, particularly if the supporting medium is soil. The review addresses the general arrangement of the foundation, with particular emphasis on methods of transferring loads from the structure to the foundation media. 3.8.5-3 Revision 3 - May 2010 D. Other Category I Foundations The foundations for other Seismic Category I 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 with foundations subject to such a review are fuel storage buildings, control buildings, diesel generator buildings, intake structures, and cooling towers. The review also includes the foundations of safety-related structures that, because of other design provisions, are not classified as Seismic Category I. 2. Applicable Codes, Standards, and Specifications. The review addresses information pertaining to design codes, standards, specifications, regulatory guides (RGs), and other industry standards that are applied in the design, fabrication, construction, testing, and surveillance of Seismic Category I foundations. 3. Loads and Load Combinations. The review includes information pertaining to the applicable design loads and their various combinations. The loads normally applicable to Seismic Category I foundations are the same as those applicable to the structures that the foundations support. SRP Section 3.8.1, Subsection I.3 describes these loads for the containment foundation, and SRP Section 3.8.4, Subsection I.3 details such loads for all other Seismic Category I foundations. 4. Design and Analysis Procedures. The review assesses design procedures used for Seismic Category I foundations other than containment, emphasizing the extent of compliance with American Concrete Institute (ACI) 349, with additional guidance
