Content:
behavior of the containment may be treated by the same method used for localized loads as discussed in SRP Subsection II.4.C. J. Steel Liner Plate and Anchors. For the design and analysis of the liner plate and its anchorage system, the procedures furnished are found adequate and acceptable if in accordance with the provisions of Subarticle CC-3600 of the ASME Code. In general, the liner plate analysis should consider deviations in geometry resulting from fabrication and erection tolerances and variations of the assumed physical properties of the liner and anchor material. Since the liner plate is usually anchored at relatively closely spaced intervals, the analysis procedures are acceptable if based on either the classical plate or beam theory. Since the concrete shell is much stiffer than the liner plate, the strains in the liner will essentially follow those in the concrete. The strains in the concrete under the various load combinations as obtained from the analysis of the shell are thus imposed on the liner plate, and the resulting strains and stresses in the liner and its anchors should be lower than the allowable limits defined in Tables CC-3720-1 and CC-3730-1 of the ASME Code. K. Ultimate Capacity of Concrete Containment. Regulatory criteria require a determination of the internal pressure capacity for containment structures, as a measure of the safety margin above the design-basis accident pressure. The design and analysis procedures are acceptable if performed in accordance with RG 1.216. L. Structural Audit. Appendix B to SRP Section 3.8.4 describes the conduct of a structural audit. M. Design Report. The design report is considered acceptable when it satisfies the guidelines of Appendix C to SRP Section 3.8.4. 3.8.1-16 Revision 4 - September 2013 5. Structural Acceptance Criteria A. For the structural portions of the containment, the specified allowable limits for stresses and strains are acceptable if they are in accordance with Subsection CC-3400 of
