REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of plant design for protection of structures, systems, and components from internal and external hazards Secondary - Organization responsible for the review of meteorological data I. AREAS OF REVIEW Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix A, General Design Criterion (GDC) 2, “Design bases for protection against natural phenomena,” requires structures, systems, and components (SSCs) important to safety to be designed to withstand the effects of natural phenomena such as tornadoes and hurricanes without loss of capability to perform their safety functions. GDC 4, “Environmental and dynamic effects design bases,” requires, in part, that SSCs important to safety be appropriately protected against dynamic effects, including missiles that may result from events and conditions outside the nuclear power unit. 3.5.1.4-2 Draft Revision 4 –July 2013 The specific areas of review are as follows: 1. The staff reviews and evaluates the applicant’s assessment of possible hazards attributable to missiles generated by high-speed winds, such as tornado, hurricane, and any other extreme winds identified in Section 3.5 of the Safety Analysis Report (SAR), to ensure that the applicant has chosen and properly characterized appropriate design-basis missiles, and to ensure that the effects caused by those missiles are acceptable. Missiles generated by design-basis tornadoes and hurricanes are considered in the plant design bases for all plants. Missiles from any other extreme winds are considered on a case-by-case basis when they are identified. 2. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) application reviews, the staff reviews the applicant's proposed ITAAC associated with the SSCs related to this Standard Review Plan (SRP) section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses,
