REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of plant design for protection of structures, systems, and components form internal and external hazards Secondary - None. I. AREAS OF REVIEW 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. Currently, missiles generated by design-basis tornadoes are considered in the plant design bases for all plants. Missiles from hurricane and 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) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and 3.5.1.4-2 Revision 3 - March 2007 Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of review are identified and addressed as appropriate in accordance with SRP Section 14.3. 3. COL Action Items and Certification Requirements and Restrictions. For a DC application, the review will also address COL action items and requirements and restrictions (e.g., interface requirements and site parameters). For a COL application referencing a DC, a COL applicant must address COL action items (referred
