Content:
ion of safety-related steel structures and steel-plate composite (SC) walls for other than reactor vessels and containments. This guide endorses, with exceptions and clarifications, the procedures and standards of the 2018 edition of American National Standards Institute (ANSI)/American Institute of Steel Construction (AISC) N690, “Specification for Safety-Related Steel Structures for Nuclear Facilities” (Ref. 1). Applicability This RG applies to applicants and licensees subject to Title 10 of the Code of Federal Regulations (10 CFR), Part 50, “Domestic Licensing of Production and Utilization Facilities” (Ref. 2), and 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” (Ref. 3). Applicable Regulations • Appendix A, “General Design Criteria for Nuclear Power Plants,” to 10 CFR Part 50 establishes necessary design, fabrication, construction, testing, and performance requirements for structures, systems, and components (SSCs) important to safety through general design criteria (GDC). GDC applicable to this RG include the following: o GDC 1, “Quality standards and records,” requires, in part, that SSCs “important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. Where generally recognized codes and standards are used, they shall be identified and evaluated for applicability, adequacy, and DG-1304. Page 2 sufficiency and shall be supplemented or modified as necessary to assure a quality product in keeping with the required safety function.” o GDC 2, “Design bases for protection against natural phenomena,” requires, in part, that SSCs “important to safety be designed to withstand the effects of natural phenomena . . . without loss of capability to perform their safety functions.” o GDC 4, “Environmental and dynamic effects design bases,” requires, in part, that SSCs “important to safety be designed to
