f the above loads that are normally postulated and reviewed include the following: Testing loads; normal operating loads; normal operating loads with severe environmental loads; normal operating loads 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 might be applicable also. Such 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, explosive hazards in proximity of the site and projectiles and missiles generated from activities of nearby military installations. 3. 8.1-3 Rev. I - July 1981 4. Design and Analysis Procedures The design and analysis procedures utilized for the containment are reviewed with emphasis on the extent of compliance with Article CC-3000 of the Code, 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 utilized 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. Steel penetration closures are covered by Standard Review Plan Section 3.8.2. J. Ultimate capacity of the concrete containment. k. Structural audit. 1.
