ppendix B to NUREG/CR-6486 includes proposed modular construction review criteria. 3.8.3-26 Draft Revision 4 - December 2012 G. A structural design audit is conducted as described in Appendix B to SRP Section 3.8.4. H. The applicant’s design report is considered acceptable if it satisfies the guidelines of Appendix C to SRP Section 3.8.4. 5. Structural Acceptance Criteria The structural acceptance criteria for containment internal structures described in Subsection I.1 of this SRP section are acceptable if found to be in accordance with the guidance given below. The acceptance criteria for the divider-barrier and ice-condenser elements of the ice-condenser PWR containment and the drywell of the BWR containment are presented following the criteria given for concrete and steel structures. The structural acceptance criteria for structures that use modular construction methods are reviewed 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. 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. 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
