y settings used for accident conditions may lead to an unplanned or unexpected plant trip under nonaccident conditions during a significant switchyard voltage transient. Consideration of International Standards The International Atomic Energy Agency (IAEA) works with member states and other partners to promote the safe, secure, and peaceful use of nuclear technologies. The IAEA develops Safety Requirements and Safety Guides for protecting people and the environment from harmful effects of ionizing radiation. This system of safety fundamentals, safety requirements, safety guides, and other relevant reports, reflects an international perspective on what constitutes a high level of safety. To inform its development of this RG, the NRC considered IAEA Safety Requirements and Safety Guides pursuant to the Commission’s International Policy Statement (Ref. 31) and Management Directive and Handbook 6.6, “Regulatory Guides” (Ref. 32). The following IAEA Guides were considered in the development of the RG: • Specific Safety Guide No. SSG-34, “Design of Electrical Power Systems for Nuclear Power Plants,” issued March 2016 (Ref. 33) • IAEA Nuclear Energy Series No. NG-T-3.8, “Electric Grid Reliability and Interface with Nuclear Power Plants,” issued 2012 (Ref. 34) Documents Discussed in Staff Regulatory Guidance This RG endorses, in part, the use of one or more codes or standards developed by external organizations and other third-party guidance documents. These codes, standards and third-party guidance documents may contain references to other codes, standards, or third-party guidance documents (“secondary references”). If a secondary reference has itself been incorporated by reference into NRC regulations as a requirement, then licensees and applicants must comply with that standard as set forth in the regulation. If the secondary reference has been endorsed in a RG as an acceptable approach for meeting an NRC requirement, then the standard constitutes a
