edures 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 9.5.5-11 DRAFT Rev. 3 - April 1996 procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC. For DC reviews, the diesel engine vendor 52 may not have been selected; therefore, the interaction 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 (DC). 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 scope of the DC as required by 10 CFR 52.47(a)(1)(vi-ix).53 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his review supports conclusions of the following type, to be included in the staff's safety evaluation report: The emergency diesel engine cooling water system (EDECWS) includes all piping, valves, heat exchangers, and pumps up to the points where the cooling water piping connects to the engine interfaces. The scope of review of the diesel engine cooling water system for the plant included layout drawings, process flow diagrams, piping and instrumentation diagrams, and descriptive information for the system and auxiliary supporting systems that are essential to its operation. The essential portions of the EDECWS that are necessary to
