t failure. The reviewer evaluates the results of failure modes and effects analyses in the SAR for the functioning of required system portions. 6. The performance requirements of the diesel engine are reviewed to determine the time available to provide cooling water to the diesels and the other systems that must operate to assure onsite power capability. 7. The reviewer verifies whether the EDECWS and the diesel generator can perform for extended periods with less than full electrical power generation without degradation of performance or reliability. A statement to the effect that operating procedures will require loading of the engine up to a minimum of 25 percent of full load or as specified by the manufacturer recommendation for one hour after eight hours of continuous no-load operation or as recommended by the manufacturer is acceptable. 9.5.5-10 Revision 3 - March 2007 8. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. 9. For reviews under 10 CFR Part 50, the procedures are used during
