Draft Revision 4 - December 2012 CC-3000 of the ASME Code and RG 1.136 (see SRP subsection II.3 of this section), particularly with respect to the following: A. Assumptions on boundary conditions B. Treatment of axisymmetric and nonaxisymmetric loads C. Treatment of transient and localized loads D. Treatment of the effects of creep, shrinkage, and cracking of the concrete E. A description of the computer programs used in the design and analyses F. The treatment of the effects of seismically induced tangential (membrane) shears G. The evaluation of the effects of variations in specified physical properties of materials on analytical results H. The treatment of the large, thickened penetration regions I. The treatment of the steel liner plate and its anchors (SRP Section 3.8.2 covers steel penetration closures) J. Ultimate capacity of the concrete containment K. Structural audit L. Design report submitted for review 5. Structural Acceptance Criteria. The staff reviews the design limits imposed on the various parameters that quantify the structural behavior of the containment, with emphasis on the extent of compliance with Article CC-3000 of the ASME Code and RG 1.136 (see Subsection II.3 of this SRP section), specifically with respect to allowable stresses, strains, deformations, and other parameters that quantify the margins of safety. For each load combination specified, the reviewer compares the proposed allowable limits with the acceptable limits delineated in Subsection II.5 of this SRP section. These allowable limits include the following major parameters: A. Compressive stresses in concrete, including membrane, membrane plus bending, and localized stresses B. Shear stresses in concrete, particularly those tangential (membrane) stresses induced by lateral loads C. Tensile stresses in reinforcement D. Tensile stresses in prestressing tendons E. Tensile or compressive strain limits in the liner plate, including membrane and membrane plus bending
