Appendix A, “General Design Criteria for Nuclear Power Plants,” to 10 CFR Part 50 establishes the minimum requirements for the principal design criteria for water-cooled nuclear power plants. The General Design Criteria (GDC) 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. The following GDC is of importance to evaluating postulated explosions at nearby facilities and transportation routes: o GDC 4, “Environmental and dynamic effects design bases,” of Appendix A to 10 CFR Part 50, requires that nuclear power plant SSCs important to safety be appropriately protected against dynamic effects that may result from equipment failures and from events and conditions that may occur outside the nuclear power plant. These events include explosions of materials at nearby facilities or on nearby transportation routes. • 10 CFR Part 100 provides requirements for proposed sites for stationary power reactors. The following requirements are specified with respect to the scope of this RG: o 10 CFR 100.20(b), requires that the nature and proximity of hazards related to human activity (e.g., airports, dams, transportation routes, and military and chemical facilities) be evaluated to establish site characteristics for use in determining if a plant design can accommodate commonly occurring hazards, and if the risk of other hazards is very low. o 10 CFR 100.21(e), requires that potential hazards associated with nearby transportation routes, industrial, and military facilities must be evaluated and site characteristics established such that the potential hazards from such routes and facilities will pose no undue risk to the type of facility proposed at the site. • 10 CFR Part 50 provides regulations for licensing production and utilization facilities and requires applicants and licensees to assess site features that may affect the
