(SRV) and LOCAs) which would generate building vibration inertial loads (floor response spectra) and elevated temperatures. The various combinations of the above loads that are normally postulated and reviewed include construction loads, normal operating loads, normal operating loads with severe environmental loads, normal operating loads with extreme environmental loads, normal operating loads with abnormal loads, normal operating loads with severe environmental and abnormal loads, and normal operating loads with extreme environmental and abnormal loads. 3.8.4-5 Revision 3 – May 2010 The loads and load combinations described above are generally applicable to all types of structures. However, other site-related loads might also be applicable. Such loads, which are not normally combined with abnormal loads, include those induced by floods, potential aircraft crashes (nonterrorism-related incidents), explosive hazards in proximity to the site, and projectiles and missiles generated from activities of nearby military installations. 4. Design and Analysis Procedures. The review of the design and analysis procedures used for Seismic Category I structures focuses on the extent of compliance with American Concrete Institute (ACI) 349, with supplement guidance by RG 1.142 for concrete structures and American National Standard Institute (ANSI)/ American Institute of Steel Construction (AISC) N690-1994 including Supplement 2 (2004) for steel structures. The review includes the following areas: A. General assumptions on boundary conditions B. The expected behavior under loads and the methods by which vertical and lateral loads and forces are transmitted from the various elements to their supports and eventually to the foundation of the structure C. The computer programs that are used D. A design report on Seismic Category I structures (Appendix C) E. Performance of a structural audit (Appendix B) F. Design of the spent fuel pool and racks (Appendix D) G. Steel embedments
