ment. 10 CFR 50.34(f)(3)(v) requirements regarding loads and loading combinations include the following: DRAFT Rev. 2 - April 1996 3.8.1-10 d. Containment integrity should be maintained by meeting the requirements of Subarticle CC-3720 of the ASME Code, "Factored Load Category," (considering pressure and dead load alone) during an accident that releases hydrogen generated from 100% fuel clad metal-water reaction and accompanied by either hydrogen burning or added pressure from postaccident inerting (assuming carbon dioxide is the inerting agent). At a minimum, the code requirements will be met for a combination of dead load and an internal pressure of 310 kPa (45 psig) . 41 42 e. 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 containment liner in excess of the limits established in Subarticle CC-3720 of the Code. 43 The requirements of Subarticle CC-3720 of the Code shall be met when the containment structure is exposed to the following loading conditions: 1. For the Factored Load Category: D + P + [P or P ]. g1 g2 g3 2. For the Service Load Category, the strains in the containment liner shall not exceed the limits set forth in Subarticle CC-3720 when exposed to pressure P . g3 3. As a minimum design condition for either condition 1 or 2 above, the following load combination must be satisfied: D + 310 kPa (45 psig) where D = Dead load P = Pressure resulting from an accident that releases hydrogen generated from g1 100% fuel clad metal-water reaction P = Pressure resulting uncontrolled hydrogen burning g2 P = Pressure resulting from postaccident inerting assuming carbon dioxide is g3 the inerting agent44 4.
