Content:
tric power systems in nuclear power plants. Specifically, it provides guidance for meeting the general design criteria (GDC) for the safety-related portions of systems and equipment in the alternating current (AC) power systems, direct current (DC) power systems, and instrumentation and control power systems. This RG revision endorses, with exceptions and clarifications, Institute of Electrical and Electronics Engineers (IEEE) Standard (Std.) 308-2020, “IEEE Standard Criteria for Class 1E Power Systems for Nuclear Power Generating Stations” (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). Under 10 CFR Part 50, this RG applies to applicants for and holders of licenses, as defined in 10 CFR 50.2, “Definitions.” Under 10 CFR Part 52, this RG applies to applicants for and holders of combined licenses, standard design approvals and manufacturing licenses, and applicants for standard design certifications for nuclear power plants. Applicable Regulations • 10 CFR Part 50, Appendix A, “General Design Criteria for Nuclear Power Plants,” establishes the minimum requirements for principal design criteria for water-cooled nuclear power plants,1 which include the following: 1 The GDC in 10 CFR 50 Appendix A are considered to be generally applicable to other types of nuclear power units and are intended to provide guidance in establishing the principal design criteria for such other units. DG-1420, Page 2 o General Design Criteria (GDC) 1, “Quality Standards and Records,” requires, in part, that structures, systems, and components important to safety be designed, fabricated, erected, constructed, tested, and inspected to quality standards commensurate with the importance of the safety function to
