is therefore typically deferred until review of applications referencing the certified design. Depending on the nature and source of the externally generated missiles, protection 18 may be provided by missile barriers for individual components, by locating independent redundant systems in compartments located in a missile protected structure, or by subgrade location at a sufficient depth. Physical separation alone is not normally an acceptable method of missile protection for redundant safety-related systems and components located in nonmissile protected independent structures. Specific missile sources and the protection needed are considered in other SRP sections in the 3.5.1 series.19 The reviewer determines that nonsafety-related SSC are identified as requiring protection from externally generated missiles if as a result of their failure by a missile, the consequences could 3.5.2-5 DRAFT Rev. 3 - April 1996 prevent the intended safety function of a safety-related SSC. In addition, any failure of nonsafety-related SSC that could result in external missile generation should not prevent safety- related SSC from performing their intended safety function. The reviewer also verifies for those applicants referencing a certified design that SSC outside of the design certification scope that may result in external missile generation would not prevent safety-related SSC from performing their intended safety function.20 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including
