The U.S. Nuclear Regulatory Commission (NRC) has issued a revision to an existing guide in the agency's Regulatory Guide Series. This series has been 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.
Revision 3 of Regulatory Guide 1.75, “Criteria for Independence of Electrical Safety Systems,” describes a method that is acceptable to the NRC staff for complying with the NRC's regulatory requirements concerning the physical independence of the circuits and electrical equipment that comprise or are associated with safety systems. Toward that end, the guide endorses, with minor exceptions, the “Standard Criteria for Independence of Class 1E Equipment and Circuits, which the Institute for Electrical and Electronics Engineers (IEEE) promulgated on June 18, 1992, as IEEE Std. 384-1992.
In December 2003, the NRC staff published a draft of this guide as Draft Regulatory Guide DG-1129. Following the closure of the public comment period on March 12, 2004, the staff considered all stakeholder comments in the course of preparing Revision 3 of Regulatory Guide 1.75.
The NRC staff encourages and welcomes comments and suggestions in connection with improvements to published regulatory guides, as well as items for inclusion in regulatory guides that are currently being developed. You may submit comments by any of the following methods.
