sideration 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. E. For those plants to which 10 CFR 50.34(f)(3)(v) applies, the requirements regarding loads and loading combinations include the following: Containment integrity should be maintained by meeting the requirements of Subarticle CC-3720 of the ASME Code (considering pressure and dead load alone) 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 (assuming carbon dioxide is the inerting agent). At a minimum, the ASME Code requirements will be met for a combination of dead load and an internal pressure of 310 Kilo Pascals (KPa) or 45 pounds per square in gauge (psig) F. The containment structure should be designed against the loadings produced by the inadvertent full actuation of a postaccident inerting hydrogen control system (assuming carbon dioxide), excluding seismic or design-basis accident loadings. Under these conditions, the loadings should not produce strains in the
