ain function in the event of such failures. 9. The diesel engine fuel oil storage and transfer system is reviewed to verify that protection from the effects of breaks in high and moderate energy lines has been provided. Layout drawings are reviewed to assure that no high- or moderate-energy piping systems are located close to the fuel oil system or that protection from the effects of failure will be provided. The means of providing such protection will be given in Section 3.6 of the SAR, and the procedures for reviewing this information by ASB are given in the 52 corresponding SRP sections. 10. The descriptive information, related system drawings, and the results of failure modes and effects analyses in the SAR are reviewed to verify that minimum system requirements will be met following design basis accidents assuming a concurrent single DRAFT Rev. 3 - April 1996 9.5.4-10 active component failure. For each case the design will be acceptable if minimum system requirements are met. 11. The EELB reviews protective interlocks as indicated in subsection I of this SRP section. Protective interlocks in this system are acceptable if the SAR indicates that the interlocks are in conformance with Position C.1.8 of Regulatory Guide 1.9.53 12. For those plants that will use an emergency diesel generator as the alternate AC source in response to a station blackout event, the reviewer verifies the adequacy of the fuel oil supply and recharging capability, independent of preferred and onsite emergency ac power, of the emergency diesel engine fuel oil storage and transfer system in accordance with Regulatory Position C.3.3.5 of Regulatory Guide 1.155.54 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
