cceptable. Code Title ASME Boiler and Pressure Vessel Code, Section III, Division 1, Subsection NE, "Class MC Components" Regulatory Guide 1.57 Design Limits and Loading Combinations for Metal Primary Reactor Containment System Components 3. Loads and Loading Combinations Subsection NE of the Code, Section III, Division 1 and Regulatory Guide 1.57 are not explicit with respect to the loads and load combinations which should be considered in 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 --- Dead loads. L --- Live loads including all loads resulting from platform flexibility and deformation, and crane loading if applicable. Pt ~~Test pressure. 3.8.2-7 Rev. 1 - July 1981 Tt --- Test temperature. To --- Thermal effects and loads during startup, normal operating or shutdown conditions, based on the most critical transient or steady-state condition. Ro --- Pipe reactions during startup, normal operating or shutdown conditions, based on the most critical transient or steady- state condition. P. --- External pressure loads resulting from pressure variation ° either inside or outside containment. E --- Loads generated by the operating basis earthquake including sloshing effects, if applicable. El --- Loads generated by the safe shutdown earthquake including sloshing effects, if applicable. Pa --- Pressure load generated by the postulated pipe break accident including PO, pool swell and subsequent hydrodynamic loads. Ta --- Thermal loads under thermal conditions generated by the postulated pipe break accident including T , pool swell, and subsequent hydrodynamic reaction loads. 0 Ra--- Pipe reactions under thermal conditions generated by the postulated pipe break accident including R., pool swell, and subsequent hydrodynamic reaction loads. Ps --- All pressure loads which are caused by the actuation of safety relief valve discharge including pool swell and subsequent
