NRC requirement, then the standard constitutes a method acceptable to the NRC staff for meeting that regulatory requirement as described in the specific RG. If the secondary reference has neither been incorporated by reference into NRC regulations nor endorsed in a RG, then the secondary reference is neither a legally binding requirement nor a “generic” NRC approved acceptable approach for meeting an NRC requirement. However, licensees and applicants may consider and use the information in the secondary reference, if appropriately justified, consistent with current regulatory practice, and consistent with applicable NRC requirements. DG-1420, Page 6 C. STAFF REGULATORY GUIDANCE The NRC staff finds that IEEE Std. 308-2020 provides methods acceptable for complying with the design, operation, and testing requirements for electric power systems, subject to the following exceptions and clarifications. 1. This RG does not endorse Section 2, “Normative References,” of IEEE Std. 308-2020. The following RGs contain additional information for the design, operation, and testing requirements for electric power systems. • RG 1.28, “Quality Assurance Program Criteria (Design and Construction),” (Ref. 19) which endorses ASME NQA-1, with clarifications. • RG 1.89, “Environmental Qualification of Certain Electric Equipment Important to Safety for Nuclear Power Plants,” (Ref. 20) which endorses IEC/IEEE 60780-323, with clarifications. • RG 1.152, “Criteria for Use of Computers in Safety Systems of Nuclear Power Plants,” (Ref. 21) which endorses IEEE 7-4.3.2, with clarifications. • RG 1.63, “Electric Penetration Assemblies in Containment Structures for Nuclear Power Plants,” (Ref. 22) which endorses IEEE Std. 317, with clarifications. • RG 1.118, “Periodic Testing of Electric Power and Protection Systems,” (Ref. 23) which endorses IEEE Std. 338, with clarifications. • RG 1.75, “Criteria for Independence of Electrical Safety Systems,” (Ref.
