d. E. Structural Audit A structural audit, as described in SRP Section 3.8.4, Appendix B. is conducted. 5. Structural Acceptance Criteria. The review evaluates the design limits imposed on the various parameters that quantify the structural behavior of the various interior structures of the containment, particularly with respect to stresses, strains, deformations, and factors of safety against structural failure, with emphasis on the extent of compliance with the applicable codes indicated in Subsection II.5 of this SRP. 6. Materials, Quality Control, and Special Construction Techniques. The review evaluates the information provided on the materials that are used in the construction of the containment internal structures. Concrete ingredients, reinforcing bars and splices, structural steel, and various supports and anchors are among the major materials of construction reviewed. The review evaluates the quality control program proposed for the fabrication and construction of the containment internal structures, including nondestructive examination of the materials to determine physical properties, placement of concrete, and erection tolerances. Special, new, or unique construction techniques, such as the use of modular construction methods, if proposed, are reviewed on a case-by-case basis to determine their effects on the structural integrity of the completed containment internal structures. 3.8.3-13 Revision 2 - March 2007 In addition, the following information should be provided: A. The extent to which the materials and quality control programs comply with American Concrete Institute (ACI) 349, as supplemented by additional guidance provided by Regulatory Guides (RG) 1.142 and 1.199 for concrete and anchors (steel embedments), respectively, and American National Standards Institute/American Institute of Steel Construction (ANSI/AISC) N690-1994 including Supplement 2 (2004), for steel, as applicable. B. If welding of reinforcing bars is proposed, describe the
