EXTERNALLY GENERATED MISSILES REVIEW RESPONSIBILITIES Primary - AuxiliaryPlant Systems Branch (ASB)(SPLB)1 Secondary - None I. AREAS OF REVIEW The ASBSPLB review of the structures, systems, and components (SSC) to be protected from 2 externally generated missiles includes all safety-related SSC on the plant site that have been provided to support the reactor facility. These include such elements as essential service water intakes, buried components (e.g., essential service water piping, storage tanks), and access openings and penetrations in structures. The ASBSPLB reviews the functional operations or performance requirements for SSC to 3 assure conformance with the requirements of General Design Criteria 2 and 4 and identifies the SSC that are necessary for the safe shutdown of the reactor facility and the SSC whose failure could result in a significant release of radioactivity. Safety-related SSC are reviewed with respect to their capability to perform functions required for attaining and maintaining a safe shutdown condition during normal or accident conditions, mitigating the consequences of an accident, or preventing the occurrence of an accident assuming impact from externally generated missiles. If the turbine is not properly oriented, AEB will request ASB toSPLB will also review 4 the protection of SSC from the effects of turbine missiles. Based on their relation to safety, structures or areas of structures, systems or portions of systems, and components are identified as requiring protection from externally generated missiles if a missile could prevent the intended safety function, or if as a result of missile impact on a DRAFT Rev. 3 - April 1996 3.5.2-2 nonsafety-related SSC, its failure could degrade the intended safety function of a safety-related SSC. Review Interfaces:5 The SPLB also performs the following review under the SRP sections indicated:6 Specific missile sources and the protection needed are reviewed under SRP Sections 3.5.1.1, 3.5.1.2,
