c Power Systems at Nuclear Power Plants." The applicant has also met the positions of Branch Technical 52 Position ICSB-17(PSB), "Diesel Generator Protective Trip Circuit Bypasses," and NUREG/CR-0660, "Enhancement of Onsite Emergency Diesel Generator 53 Reliability." The applicant has met the requirements of the following industry standards: IEEE Stdandard 387, "IEEE Standard Criteria for Diesel Generator 54 Units Applied as Standby Power Supplies for Nuclear Power Generating Stations," and Diesel Engine Manufacturers Association (DEMA) Standard. If the applicant proposes to designate an emergency diesel generator as the alternate AC source in response to a station blackout event, the following finding should be included: The applicant has met the requirements of 10 CFR 50.63, "Loss of All Alternating Current Power," relevant to the design of the EDESS for the Alternate ac power source. The EDESS supporting the Alternate ac power source can start its associated diesel DRAFT Rev. 3 - April 1996 9.5.6-10 generator and system can be recharged independent of preferred and onsite emergency ac power for the specified duration of the station blackout. This meets the positions of Regulatory Guide 1.155 "Station Blackout."55 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.56 V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. 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 57 cases in which the applicant
