Start Preamble

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 4 of Regulatory Guide 1.97, entitled “Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants,” describes a method that the NRC staff considers acceptable for use in complying with the agency's regulations with respect to satisfying criteria for accident monitoring instrumentation in nuclear power plants. Specifically, the method described in this regulatory guide relates to General Design Criteria 13, 19, and 64, as set forth in Appendix A to Title 10, Part 50, of the Code of Federal Regulations (10 CFR part 50), “Domestic Licensing of Production and Utilization Facilities.” In addition, Subsection (2)(xix) of 10 CFR 50.34(f), “Additional TMI-Related Requirements,” requires operating reactor licensees to provide adequate instrumentation for use in Start Printed Page 39374monitoring plant conditions following an accident that includes core damage.

This revision of Regulatory Guide 1.97 represents an ongoing evolution in the nuclear industry's thinking and approaches with regard to accident monitoring systems for nuclear power plants. Specifically, this revision endorses (with certain clarifying regulatory positions specified in Section C of the revised guide) the “Criteria for Accident Monitoring Instrumentation for Nuclear Power Generating Stations,” which the Institute of Electrical and Electronics Engineers (IEEE) promulgated as IEEE Std. 497-2002.

This revised regulatory guide is intended for licensees of new nuclear power plants.[1] Previous revisions of this regulatory guide remain in effect for licensees of current operating reactors,1 who are unaffected by this proposed revision. (See regulatory position #1 in Section C of the revised guide for information regarding the applicability of IEEE Std. 497-2002 for current operating reactors.)

The NRC previously solicited public comment on this revised guide by publishing a Federal Register notice (70 FR 49953) concerning Draft Regulatory Guide DG-1128 on August 25, 2005. Following the closure of the public comment period on October 14, 2005, the staff considered all stakeholder comments in the course of preparing Revision 4 of Regulatory Guide 1.97. The staff's responses to all comments received are available in the NRC's Agencywide Documents Access and Management System (ADAMS) at http://www.nrc.gov/​reading-rm/​adams.html, under Accession #ML061580516.
