dent and physically separated from the other system serving the redundant diesel generator. A single failure in any one of the systems will affect only the associ- ated diesel generator. The EDELS for each diesel engine provides the necessary engine lubrication during operation and maintains the lube oil at a temperature that improves first-start reli- ability. This meets the positions of Regulatory Guide 1.9, "Selection, Design, and Qualification of Diesel Generator Units 9.5.7-7 Rev. 2 - July 1981 Used as Standby (Onsite) Electric Power Systems at Nuclear Power Plants." The applicant has also met the positions of Branch Technical Position ICSB-17 (PSB), "Diesel Generator Protective Trip Circuit Bypasses," and NUREG/CR-0660, "Enhance- ment of Onsite 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. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those 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. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced regulatory guides and NUREG. VI.
