ch 2007 RG 1.70 provides guidance for information to be submitted with an application for construction permit (CP) or operating license (OL). 2. Applicable Codes, Standards, and Specifications. Codes, standards, and specifications, acceptable either in their entirety or in part, cover the design, materials, fabrication, erection, inspection, testing, and inservice surveillance of steel containments. The following codes and guides are acceptable: Code/Guide Title ASME Code Section III, Division 1, Subsection NE, “Class MC Components” ASME Code Section XI, Subsection IWE, “Requirements for Class MC and Metallic Liners of Class CC Components of Light-Water Cooled Plants” RG 1.7 Control of Combustible Gas Concentrations in Containment RG 1.57 Design Limits and Loading Combinations for Metal Primary Reactor Containment System Components 3. Loads and Loading Combinations. Currently, ASME Code, Section III, Division 1, Subsection NE, and RG 1.57 do not explicitly state the loads and load combinations that should be considered in the design of steel containments. The staff has issued as a proposed revision to RG 1.57, “Design Limits and Loading Combinations for Metal Primary Reactor Containment System Components.” This draft guide or subsequent revision to RG 1.57 provides additional guidance for design requirements, including load 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 from crane loading, if applicable Pt — Test pressure 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 3.8.2-11 Revision 2 - March 2007 Ro — Pipe reactions during startup, normal operating, or
