Content:
tes the results of failure modes and effects analyses presented in the SAR to assure functioning of required components, traces the availability of these components on system drawings, and checks that minimum system requirements are met for each degraded situation over required time spans. For each case, the design is acceptable if minimum system requirements are met. 5. For those plants that will use an emergency diesel generator as the AAC source in response to a station blackout event, the reviewer verifies the adequacy of the EDELS to DRAFT Rev. 3 - April 1996 9.5.7-10 support this functional capability, independent of preferred and onsite emergency ac power, by comparing system design with regulatory position C.3.3.5 of Regulatory Guide 1.155.50 For standard design certification reviews under 10 CFR 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 the site parameters, interface criteria, and ITAAC. At the time of DC reviews the diesel engine 51 vendor may not have been selected; therefore, the interfaces between the diesel engine and the support (auxiliary) systems may not be fully defined. Portions of the EDE and associated support systems design may be considered outside the scope of the design submitted by applicants for design certification. Portions of the design determined not to be within the DC scope are the responsibility of the applicant referencing the certified design. The DC applicant's submittal should provide a conceptual design and interface requirements for that portion of the design outside the
