Content:
10 kPa (45 psig) where D = Dead load Pg1 = Pressure resulting from an accident that releases hydrogen generated from 100-percent metal-water reaction of the fuel cladding Pg2 = Pressure resulting from uncontrolled hydrogen burning Pg3 = Pressure resulting from postaccident inerting, assuming carbon dioxide is the inerting agent 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. An analytical technique accepted by the NRC staff should demonstrate the containment structural integrity. This analysis should include sufficient supporting justification to show that the technique 3.8.1-12 Revision 3 - May 2010 describes the containment response to the structural loads involved. RG 1.7 presents further guidance on the analytical technique, loads, loading combination, and acceptance criteria. 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 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 for use in the load combination for construction given in Table CC-
