EXTERNALLY-GENERATED MISSILES REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of plant design for protection of structures, systems, and components from internal and external hazards Secondary - None I. AREAS OF REVIEW The review of the structures, systems, and components (SSCs) to be protected from externally-generated missiles includes all plant site safety-related SSCs supporting the reactor facility, such elements as essential service water intakes, buried components (e.g., essential service water piping, storage tanks), and structure access openings and penetrations. The specific areas of review are as follow: 1. The functional operations or performance requirements for SSCs are reviewed for compliance with 10 CFR 50, Appendix A, General Design Criteria (GDCs) 2 and 4 requirements and SSCs necessary for the safe shutdown of the reactor facility and SSCs, the failure of which could result in a significant release of radioactivity, are identified. 3.5.2-2 Revision 3 - March 2007 2. Safety-related SSCs are reviewed for their capability to perform functions required to attain and maintain safe shutdown conditions during normal or accident conditions, mitigating the consequences of an accident, or preventing the occurrence of an accident, assuming impact from externally-generated missiles. 3. If the turbine is not properly oriented, the protection of SSCs from the effects of turbine missiles is reviewed. Based on their relation to safety, structures or areas of structures, systems or portions of systems, and components require protection from externally-generated missiles if they could prevent an intended safety function or if, as a result of missile impact on a nonsafety-related SSC, its failure could affect the intended safety function of a safety-related SSC. 4. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC
