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. As augmented by Regulatory Guide 1.142 (Ref. 6) * 3.8.5-3 DRAFT Rev. 2 - April 1996 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, 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. 2. Applicable Codes, Standards, and Specifications Information pertaining to design codes, standards, specifications, regulatory guides, and other industry standards that are applied in the design, fabrication, construction, testing, and surveillance of seismic Category I foundations is reviewed. 3. Loads and Load Combinations Information pertaining to the applicable design loads and their various combinations is reviewed. The loads normally applicable to seismic Category I foundations are the same as those applicable to the structures which the foundations support. These loads are described in subsection I.3 of SRP Section 3.8.4. 4. Design and Analysis Procedures The design procedures used for seismic Category I foundations are reviewed, with emphasis on the extent of compliance with the ACI 349 Code (Ref. l) for concrete * 3 structures and with the AISC N690 Specifications (Ref. 2) for steel structures. The 4 analysis procedures used for seismic Category I foundations are reviewed with respect to the applicability of the theories on which these procedures are based. Among the areas reviewed are the following: a. The assumptions made on boundary conditions and
