Loads and Loading Combinations. The specified loads and load combinations are acceptable if found to be in accordance with Article CC-3000 of the ASME Code with the exceptions listed below applied to the requirements specified in Table CC-3230-1. RG 1.136, “Design Limits, Loading Combinations, Materials, Construction, and Testing of Concrete Containments,” provides additional guidance for design requirements, including load and load combinations, which should be considered in the design of concrete containments. A. The maximum values of Pa, Ta, Ra, Rrr, Rrj, and Rrm should be applied simultaneously, where appropriate, unless a time-history analysis is performed to justify doing otherwise. B. Hydrodynamic loads resulting from LOCA and/or SRV actuation should be combined as indicated in the appendix to this SRP section. Fluid structure interaction associated with these hydrodynamic loads and those from earthquakes should be considered. C. As noted in Appendix S to 10 CFR Part 50, the OBE is only associated with plant shutdown and inspection unless specifically selected by the applicant as a design input. If the OBE is set at one-third or less of the SSE ground motion, an explicit response or design analysis is not required. If the OBE is set at a value greater than one-third of the SSE, an analysis and design must be performed to demonstrate that the containment remains functional and is within applicable stress, strain, and deformation limits. SRP Section 3.7 provides further
