sites for commercial nuclear power stations1. Applicability This RG applies to applicants for commercial nuclear power reactor licenses and approvals under Title 10 of the Code of Federal Regulations (10 CFR) Part 50, “Domestic Licensing of Production and Utilization Facilities” (Ref. 1), and 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” (Ref. 2), and addresses requirements in 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions” (Ref. 3), and 10 CFR Part 100, “Reactor Site Criteria” (Ref. 4). Applicable NRC Regulations • 10 CFR Part 50 governs the licensing of nuclear power plants, including issuance of construction permits and operating licenses. Appendix A, “General Design Criteria for Nuclear Power Plants,” to 10 CFR Part 50 provides general design criteria (GDC) for water-cooled nuclear power plants2. GDC 2, “Design bases for protection against natural phenomena,” requires that structures, systems, and components (SSCs) important to safety be designed to withstand the effects of 1 For the purpose of this guide, the term “commercial nuclear power station” is equivalent to “nuclear power plant” and refers to the nuclear reactor unit or units, nuclear steam supply, electric generating units, auxiliary systems (including the cooling systems) and structures such as docks that are located on a given site, and any new electrical transmission towers and lines erected in connection with the facilities. 2 The General Design Criteria are also considered to be generally applicable to other types of nuclear power units and are intended to provide guidance in establishing the principal design criteria for such other units. DG-4034, Page 2 expected natural phenomena when combined with the effects of normal accident conditions without loss of capability to perform their safety function. • 10 CFR Part 51 provides regulations applicable to the
