te Emergency Diesel Generator Reliability." The applicant has met the requirements of the following industry standards: IEEE Standard 387, "IEEE Standard Criteria for Diesel Generator Units Applied as Standby Power Supplies for Nuclear Power Generating Stations," and Diesel Engine Manufacturer Association (DEMA) Standard. If the applicant proposes to designate an emergency diesel generator as the AAC source in response to a station blackout event, the following finding should be included: The applicant has met the requirements of 10 CFR Part 50.63, "Loss of All Alternating Current Power," relevant to the design of the EDELS for the Alternate ac power source. The EDELS for the Alternate ac power source can perform its lubrication functions for its associated diesel generator independent of preferred and onsite emergency ac power for the specified duration of the station blackout. This meets the applicable positions of Regulatory Guide 1.155 "Station Blackout."56 For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff's evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site interface requirements, and combined license action items that are relevant to this SRP Section.57 V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. DRAFT Rev. 3 - April 1996 9.5.7-12 This SRP section will be used by the staff when performing safety evaluations of license applications submitted by applicants pursuant to 10 CFR 50 or 10 CFR 52. Except in those 58 cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations.
