should be as indicated in the appendix to SRP Section 3.8.1. Fluid-structure interaction associated with these hydrodynamic loads and those from earthquakes should be taken into account. The design of concrete structures needs to consider the loads and load combinations that may occur during their construction. These loads consist of dead loads, live loads, temperature, wind, snow, rain, ice, and construction loads that may be applicable such as material loads, personnel and equipment loads, horizontal construction loads, erection and fitting forces, equipment reactions, and form pressure. Structural Engineering Institute (SEI)/American Society of Civil Engineers (ASCE) Standard 37 gives additional guidance on construction loads. This standard provides supplemental guidance, and in cases where the criteria in the standard and in the Code/SRP conflict, then the Code/SRP shall govern. 3.8.4-11 Revision 4 – September 2013 The analysis should consider other site-related or plant-related loads applicable to seismic Category I structures outside the containment such as floods, explosive hazards in proximity to the site, potential aircraft crashes (non- terrorism-related incidents), and missiles generated from activities of nearby military installations or turbine failures. The inclusion of these loads and the related load combinations are reviewed on a case-by-case basis. B. Steel Structures All loads and load combinations are to be in accordance with AISC N690-1994 including Supplement 2 (2004). This specification uses the allowable stress design method. The supplemental criteria on the use of loads and load combinations presented above for concrete structures also apply to steel structures. 4. Design and Analysis Procedures. The design and analysis procedures used for seismic Category I structures, including assumptions about boundary conditions and expected behavior under loads, are acceptable if found to be in accordance with the following: A. For concrete
