ads with extreme environmental loads; normal operating loads with abnormal loads; normal operating loads with severe environmental and abnormal loads; normal operating loads with extreme environmental and abnormal loads; and post-LOCA flooding loads with severe environmental loads, if applicable. The loads and load combinations described above are generally applicable to all containments. However, other site-related design loads may also apply. Any loads, which are not normally combined with abnormal loads, are reviewed on a case-by-case basis. They include those loads induced by floods, potential aircraft crashes 3.8.1-5 Revision 4 - September 2013 (nonterrorism-related incidents), explosive hazards in proximity to the site, and projectiles and missiles generated from activities of nearby military installations. 4. Design and Analysis Procedures. The staff reviews the design and analysis procedures used for the containment with emphasis on the extent of compliance with Article CC-3000 of the ASME Code, with additional guidance provided by 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. Description of the computer programs used in the design and analyses F. Treatment of the effects of seismically induced tangential (membrane) shears G. Evaluation of the effects of variations in specified physical properties of materials on analytical results H. Treatment of the large, thickened penetration regions I. 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
