s located near the system. Reference to the SAR sections describing site features and the general arrangement and layout drawings will be neces- sary in this determination. Plant arrangement features, in conjunction with the protection obtained by location and the design of the system and structures, are considered in determining the ability of the system to maintain 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 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 active component failure. For each case the design will be acceptable if minimum system requirements are met. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and that his review supports conclusions of the following type, to be included in the staff's safety evaluation report: The emergency diesel engine fuel oil storage and transfer system (EDEFSS) includes storage tanks, fill, vent, stick gauge drain, and overflow return lines, fuel oil transfer pumps, strainers, filters, valves, day tanks, and all components and piping up to the connections to the engine interfaces. The scope of review of the diesel engine fuel oil storage and transfer system for the plant included layout drawings, piping and instrumentation diagrams, and
