l Design Criterion (GDC) 1, “Quality Standards and Records,” requires, in part, that structures, systems, and components important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. o 10 CFR Part 50, Appendix A, GDC 17, “Electric Power Systems,” requires, in part, that an onsite electric power system and an offsite electric power system be provided to permit functioning of structures, systems, and components important to safety. • 10 CFR Part 52 governs the issuance of early site permits, standard design certifications, combined licenses, standard design approvals, and manufacturing licenses for nuclear power facilities. Part 52 specifies, among other things, that contents of some applications must satisfy the requirements of 10 CFR Part 50, Appendix A; 10 CFR 50.55a; and 10 CFR 50.63, “Loss of all alternating current power.” Related Guidance • NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: Light-Water Reactor (LWR Edition)” (Ref. 4), provides guidance to the NRC staff in performing safety reviews under 10 CFR Part 50 and 10 CFR Part 52. Specifically, Section 8.3.2, “DC Power Systems (Onsite),” contains review guidance related to direct current (dc) systems, including batteries. • RG 1.129, “Maintenance, Testing, and Replacement of Vented Lead-Acid Storage Batteries for Nuclear Power Plants and Utilization Facilities” (Ref. 5), endorses, with clarifications, IEEE Std. 450, “IEEE Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-Acid Batteries for Stationary Applications” (Ref. 6), as an acceptable method to meet the regulations concerning the maintenance, testing, and replacement of vented lead-acid storage batteries in nuclear power plants. • RG 1.128, “Installation Design and Installation of Vented Lead-Acid Storage Batteries for Nuclear Power
