r use in nuclear power plants. The report outlines the technical basis for the acceptance of this new specification and the technical background for additional staff guidance. This guide considers the aforementioned technical background and provides updated regulatory guidance for the design, fabrication, and erection of safety-related steel and SC walls other than reactor vessels and containments. The nuclear industry and the NRC staff can use this new design and review guidance as needed for new reactor designs, including small modular reactors and advanced nonlight-water designs, and the guidance is available for the review of license amendments for operating plants that invoke the new guidance and use SC or steel structures. 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 Standards DG-1304. Page 6 and Safety Guides for protecting people and the environment from harmful effects of ionizing radiation. These standards and guides provide a system of safety fundamentals, safety requirements, and safety guides reflecting an international perspective on what constitutes a high level of safety. In developing or updating Regulatory Guides, the NRC has considered IAEA Safety Standards and Safety Guides in order to benefit from the international perspectives.1 The following IAEA Safety Guides incorporate similar design and preoperational testing guidelines and is consistent with the basic safety principles considered in developing this Regulatory Guide: • Safety Guide NS-G-1.5, “External Events Excluding Earthquakes in the Design of Nuclear Power Plants,” issued 2003 (Ref. 17) • Safety Guide NS-G-1.6, “Seismic Design and Qualification for Nuclear Power Plants,” issued 2003 (Ref. 18) • Safety Guide NS-G-2.6, “Maintenance, Surveillance and In-service Inspections in Nuclear Power
