Draft Revision 4 - December 2012 E. Those loads to be sustained during extreme environmental conditions, including those induced by the design-basis tornado and the safe-shutdown earthquake (SSE) specified for the plant site. F. Those loads to be sustained during abnormal plant conditions, which include loss-of-coolant accidents (LOCAs). The main abnormal plant condition for containment design is the design-basis LOCA. Other accidents involving various high-energy pipe ruptures are also considered. Loads induced on the containment by such accidents include elevated temperatures and pressures and possibly localized loads such as jet impingement and associated missile impact. For BWR containments, the review should consider the LOCA- and SRV-related hydrodynamic loads in suppression pools manifested as jet loads and/or pressure loads. Appendix A to this SRP section describes loads associated with LOCAs. G. Those loads to be sustained, if applicable, after abnormal plant conditions, including flooding of the containment subsequent to a LOCA to maintain core cooling and/or fuel recovery. H. For those plants to which Title 10 of the Code of Federal Regulations (10 CFR) 50.34(f)(3)(v) applies, pressure and dead loads during an accident that releases hydrogen generated from 100-percent metal-water reaction of the fuel cladding and accompanied by either hydrogen burning or added pressure from postaccident inerting, and the loadings produced by the inadvertent full actuation of a postaccident inerting hydrogen control system, excluding seismic or design- basis accident loadings. I. Loads associated with combustible gas generation from a metal-water reaction of the fuel cladding in accordance with 10 CFR 50.44, which define the applicable plants that must consider this loading and the percent fuel cladding to consider. The various combinations of the above loads that are normally postulated and reviewed include construction loads; testing loads; normal operating loads; normal
