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 Staff reviews and inspections for extreme wind missile protection are based on applicable regulations and the requirements contained in the current licensing bases documents, typically the updated final safety analysis report (FSAR) or for a combined license (COL) referencing a standard design certification (DC), the final safety evaluation report and referenced design control document. When evaluating for conformance with the licensing basis for extreme wind missile protection, in the absence of specific descriptions of protective features for extreme wind missile protection, including procedures and repairs, contained in the licensing basis documents, the staff relies on U.S. Nuclear Regulatory Commission (NRC) regulations and guidance provided in regulatory guides and the standard review plans to interpret any generalities in a plant’s licensing basis. 3.5.1.4-2 Revision 4 - March 2015 Title 10 of the Code of Federal Regulations (10 CFR) Part 50, “Domestic Licensing of Production and Utilization Facilities,” 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. The specific areas of review are as follows: 1. The staff reviews and evaluates the applicant’s
