UCTION This guide describes updated methods that the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable for use in complying with the Commission’s requirements regarding fuel oil systems for safety-related emergency diesel generators and oil-fueled gas turbine generators, including assurance of adequate fuel oil quality. The guidance provided herein may also be applied to the fuel oil systems for nonsafety-related standby power supplies to the extent deemed appropriate to the safety significance of the power supplies. Title 10, of the Code of Federal Regulations, Part 50, “Domestic Licensing of Production and Utilization Facilities” (10 CFR Part 50) (Ref. 1), Appendix A, “General Design Criteria for Nuclear Power Plants,” General Design Criteria (GDC) 17, “Electric Power Systems,” requires, in part, that an onsite electric power system and an offsite electric power system be provided to permit functioning of structures, systems, and components important to safety. In addition, Criterion 17 contains requirements concerning system capacity, capability, independence, redundancy, availability, testability, and reliability. The NRC issues regulatory guides to describe to the public methods that the staff considers acceptable for use in implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific problems or postulated accidents, and to provide guidance to applicants. Regulatory guides are not substitutes for regulations and compliance with them is not required. This regulatory guide contains information collection requirements covered by 10 CFR Part 50 and Title 10, of the Code of Federal Regulations, Part 52, ALicenses, Certifications, and Approvals for Nuclear Power Plants” (10 CFR Part 52) (Ref. 2) that the Office of Management and Budget (OMB) approved under OMB control numbers 3150-0011 and 3150-0151, respectively.
