II. Further Information Back to Top
The NRC is issuing for public comment a draft guide in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public such information as methods that are acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.
The draft regulatory guide, entitled, “Fuel Oil Systems for Emergency Power Supplies,” is temporarily identified by its task number, DG-1282. The DG-1282 is proposed revision 2 of Regulatory Guide 1.137, “Fuel Oil Systems for Standby Diesel Generators” dated April 1979.
This guide describes a method that the NRC staff 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.
Proper quantity and quality of fuel oil is necessary for proper operation of the emergency diesel generators and gas turbine generators. Appendix C to ANSI/ANS-59.51-1997, “Recommended Fuel Oil Practices,” addresses recommended practices for maintaining fuel oil quantity and quality. Although not a mandatory part of the standard, the NRC staff believes Appendix C serves as an acceptable basis for a program to maintain the quality of fuel oil, with additions, deletions, and clarifications as contained in this guide.
Dated at Rockville, Maryland, this 26th day of June, 2012.
