Start Preamble

The U.S. Nuclear Regulatory Commission (NRC) has issued for public comment a draft of a new 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.

The draft regulatory guide, entitled “Combined License Applications for Nuclear Power Plants (LWR Edition),” is temporarily identified by its task number, DG-1145, which should be mentioned in all related correspondence. This proposed regulatory guide contains guidance for use in submitting combined license (COL) applications in compliance with the Commission's regulations in Title 10 Part 52 of the Code of Federal Regulations (10 CFR Part 52), “Early Site Permits; Design Certifications; and Combined Licenses for Nuclear Power Plants.” Specifically, 10 CFR Part 52 governs the issuance of early site permits, standard design certifications, and combined licenses for nuclear power plants.

In February 1972, the NRC initially published Regulatory Guide 1.70, “Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants (LWR Edition),” which the nuclear industry has since used in preparing applications for construction permits and operating licenses for new nuclear power plants. The NRC most recently revised Regulatory Guide 1.70 in November 1978 and, since that time, the Commission has established a new process for licensing new reactors. That process, described in detail in 10 CFR Part 52, allows an applicant to reference an early site permit (ESP), a design certification (DC), both, or neither, in a COL application. The NRC has developed Draft Regulatory Guide DG-1145 to provide guidance to applicants who plan to use this new process.

The NRC initially issued 10 CFR Part 52 in April 1989 to offer alternative licensing (ESP, standard DC, COL, and manufacturing license) processes for new nuclear power plants. More recently, the agency proposed a revision of the rule on March 13, 2006, (71 FR 12782), to clarify the applicability of various requirements to each of the licensing processes. This Draft Regulatory Guide, DG-1145, is based on the proposed revised rule. The specific requirements pertaining to technical requirements for content of applications are contained in proposed 10 CFR 52.79, “Contents of applications, general requirements” and proposed 10 CFR 52.80, “Contents of applications, additional technical information.” The final Regulatory Guide will be conformed to the final rule that is adopted by the Commission, and will be issued when that final rule is available.

At this time, the NRC staff is soliciting comments on Draft Regulatory Guide DG-1145. Comments may be accompanied by relevant information or supporting data, and should mention DG-1145 in the subject line.
