hen derived in accordance with Appendix D of IEEE Standard 344-1987. D. Where post-LOCA flooding is a design consideration for the plant, the load combination in the ASME Code containing LOCA flooding along with OBE should be considered. Where post-LOCA flooding is combined with the OBE set at one-third or less of the SSE for the plant, this load combination may be eliminated provided the load combination is shown to be less severe than one of the other load combinations. 3.8.1-12 Revision 4 - September 2013 E. For those plants to which 10 CFR 50.34(f)(3)(v) applies, RG 1.136 provides the requirements regarding loads and loading combinations due to 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. F. 10 CFR 50.44 requires that an analysis be performed that demonstrates that the containment structural integrity is maintained under loads resulting from combustible gases generated from metal-water reaction of the fuel cladding. RGs 1.7, 1.136, and 1.216 provide the requirements regarding these loads and load combinations associated with 10 CFR 50.44. G. Other site-related or plant-related loads applicable to containment such as floods, explosive hazards in proximity to the site, potential aircraft crashes (nonterrorism- related incidents), and missiles generated from activities of nearby military installations or turbine failures need to be considered. The staff reviews the inclusion of these loads in the factored load combinations on a case-by-case basis. H. The review considers those loads encountered during construction of the containment, which include dead loads, live loads, prestress loads, temperature, wind, earth pressure, snow, rain, and ice, and construction loads that may be applicable such as material loads, personnel and equipment loads, horizontal construction loads, erection and
