vertent full actuation of the postaccident inerting hydrogen control system (assuming carbon dioxide), but not including seismic or design basis accident loadings. (See 10 CFR 50.34(f)(3)(v)(B)(1).)11 k. Those loads that are generated by pressure and dead load alone during an accident that releases hydrogen generated from 100% fuel clad metal-water reaction accompanied by either hydrogen burning or added pressure from postaccident inerting. (See 10 CFR 50.34(f)(3)(v)(A)(1).)12 The various combinations of the above loads that are normally postulated and reviewed include the following: Testing loads; normal operating loads; normal operating loads with severe environmental loads; normal operating loads with severe environmental loads and abnormal loads; normal operating loads with extreme environmental loads and abnormal loads; and post-LOCA flooding loads with severe environmental loads, if applicable. Specific and more detailed information on these combinations are delineated in subsection II.3 of this Standard Review PlanSRP section. Unless the steel containment is protected by a shield building, other site-related design loads might also be applicable, including those described in subsection I.3 of Standard Review PlanSRP Section 3.8.1. 4. Design and Analysis Procedures The design and analysis procedures utilized for the steel containment are reviewed with emphasis on the extent of compliance with Subsection NE of the Code, Section III, Division 1. Particular emphasis is placed on the following subjects: a. Treatment of nonaxisymmetric and localized loads. 13 b. Treatment of local buckling effects. c. The computer programs utilized in the design and analysis. d. Ultimate capacity of steel containment. e. Structural audit. f. Design report. 5. Structural Acceptance Criteria The design limits imposed on the various parameters that serve to quantify the structural behavior of the containment are reviewed, specifically with respect to allowable stresses, DRAFT Rev. 2 -
