-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, and may include building dynamic response 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 defines the 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 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; normal operating loads with extreme environmental
