on a case-by-case basis. See Section II.4.E of this SRP section for criteria relating to modular construction. A. Concrete Structures ACI 349 and RG 1.142 define the structural acceptance criteria for concrete structures. The structural acceptance criteria for anchors (steel embedments) used for support of systems and components to concrete structures are acceptable if found to be in accordance with Appendix B to ACI 349, with additional guidance provided by RG 1.199. 3.8.3-25 Revision 2 - March 2007 B. Steel Structures ANSI/AISC N690-1994 including Supplement 2 (2004) defines the structural acceptance criteria for steel structures. This specification uses the ASD method. Use of the LRFD version of the specification (N690L) is reviewed on a case-by-case basis. C. Divider Barrier and Ice-Condenser of PWR Ice-Condenser Containment i. Divider Barrier For concrete pressure-resisting portions of the divider barrier, the specified limits for stresses and strains are acceptable if found to be in accordance with Subsection CC-3400 of ASME Code Section III, Division 2, with additional guidance provided by applicable portions of SRP Section 3.8.1 and RG 1.136. For steel portions of the divider barrier that resist pressure but are not backed by structural concrete, the design should be similar to that of steel containments. Accordingly the stress limits are acceptable if found to be in accordance with Subsection NE of the ASME Code, Section III, Division 1, with additional guidance provided by applicable portions of SRP Section 3.8.2 and RG 1.57. For the other concrete and steel portions of the divider barrier, the specified limits for stresses and strains are acceptable if found to be in accordance with those provided in Subsections II.5.A and B for concrete and steel, respectively. ii. Ice-Condenser Elements For load combination delineated in Subsection II.3 of this SRP section, the specified limits for stresses and strain are acceptable if found to be in accordance with
