the design of steel containments. The specified loads and load combinations are acceptable if found to be in accordance with the following: A. Loads D C Dead loads L C Live loads, including all loads resulting from platform flexibility and deformation and from crane loading, if applicable Pt C Test pressure Tt C Test temperature To C Thermal effects and loads during startup, normal operating, or shutdown conditions, based on the most critical transient or steady-state condition Ro C Pipe reactions during startup, normal operating, or shutdown conditions, based on the most critical transient or steady-state condition Po C External pressure loads resulting from pressure variation either inside or outside containment E C Loads generated by the OBE, including sloshing effects, if applicable E' C Loads generated by the SSE, including sloshing effects, if applicable 3.8.2-11 Revision 3 - May 2010 Pa C Pressure load generated by the postulated pipe break accident (including pressure generated by postulated small-break or intermediate-break pipe ruptures), pool swell, and subsequent hydrodynamic loads Note: For loading combinations B, Service Conditions(iii), for (1)(d), (3)(c), and (4)(b), a small or intermediate pipe break accident is postulated; for all other load combinations, the design-basis LOCA is postulated. Ta C Thermal loads under thermal conditions generated by the postulated pipe break accident, pool swell, and subsequent hydrodynamic reaction loads Note: For loading combinations B, Service Conditions(iii), for (1)(d), (3)(c), and (4)(b), a small or intermediate pipe break accident is postulated; for all other load combinations, the design-basis LOCA is postulated. Ra C Pipe reactions under thermal conditions generated by the postulated pipe break accident, pool swell, and subsequent hydrodynamic reaction loads Note: For loading combinations B, Service Conditions(iii), for (1)(d), (3)(c), and (4)(b), a small or intermediate pipe break accident is postulated;
