ommission (NRC) to meet regulatory requirements for the qualification of safety-related or Class 1E battery chargers, inverters, and uninterruptible power supply systems for production and utilization facilities. It endorses Institute of Electrical and Electronics Engineers (IEEE) Standard (Std.) 650-2017, “IEEE Standard for Qualification of Class 1E Static Battery Chargers, Inverters, and Uninterruptible Power Supply Systems for Nuclear Power Generating Stations” (Ref. 1). Applicability This RG applies to reactor licensees subject to Title 10 of the Code of Federal Regulations (10 CFR), Part 50, “Domestic Licensing of Production and Utilization Facilities” (Ref. 2), or 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” (Ref. 3). Under 10 CFR Part 50, this RG applies to licensees or applicants for nuclear power plants and utilization facilities. Under 10 CFR Part 52, this RG applies to applicants and holders of combined licenses, standard design certifications, standard design approvals, and manufacturing licenses. Applicable Regulations • 10 CFR Part 50 requires that structures, systems, and components (SSCs) that are important to safety must be designed to accommodate the effects of environmental conditions (i.e., remain functional under postulated design basis events). o 10 CFR 50.49(b)(1) and (c)(3) define safety-related equipment and a mild environment, respectively. DG-1412 Page 2 o 10 CFR 50.55a(h)(3) requires safety systems to meet the requirements for safety systems in IEEE Std. 603-1991, “Criteria for Safety Systems for Nuclear Power Generating Stations” (Ref. 4) and the correction sheet dated January 30, 1995, if applications for construction permits and operating licenses under 10 CFR Part 50, and for design approvals, design certifications, and combined licenses under 10 CFR Part 52, were filed on or after May 13, 1999. The system criteria identified in this standard, include the qualification for the
