B. Submitting Comments The NRC encourages electronic comment submission through the Federal rulemaking website (https://www.regulations.gov). Please include Docket ID NRC-2023-0153 in your comment submission.
The NRC cautions you not to include identifying or contact information that you do not want to be publicly disclosed in your comment submission. The NRC will post all comment submissions at https://www.regulations.gov as well as enter the comment submissions into ADAMS. The NRC does not routinely edit comment submissions to remove identifying or contact information.
If you are requesting or aggregating comments from other persons for submission to the NRC, then you should inform those persons not to include identifying or contact information that they do not want to be publicly disclosed in their comment submission. Your request should state that the NRC does not routinely edit comment submissions to remove such information before making the comment submissions available to the public or entering the comment into ADAMS.
II. Additional Information The NRC is issuing for public comment a DG in the NRCs Regulatory Guide series. This series was developed to describe methods that are acceptable to the NRC 3
staff for implementing specific parts of the agencys regulations, to explain techniques that the staff uses in evaluating specific issues or postulated events, and to describe information that the staff needs in its review of applications for permits and licenses.
This DG, entitled General Site Suitability Criteria for Nuclear Power Stations, is temporarily identified by its task number, DG-4034.
This proposed revision to RG 4.7 implements the Commission approved alternative population-related criteria in SRM-SECY-20-0045, Population-Related Siting Considerations for Advanced Reactors, (ADAMS Accession No. ML22194A885) through the addition of Appendix A. It provides alternatives to demonstrate compliance with paragraph 100.21(h) of title 10 of the Code of Federal Regulations (10 CFR) in determining the suitability of sites for commercial nuclear power stations to support licensing for non-light-water reactors (LWRs) and light-water small modular reactors with attributes that could support siting a commercial nuclear power station closer to population centers than large LWRs typically have been sited. Appendix A retains the regulatory requirements in 10 CFR part 100 that call for licensees to establish an exclusion area, a low population zone, and a minimum distance to the nearest densely populated center containing more than 25,000 residents. In addition, Appendix A introduces a new graded approach where instead of locating a reactor in an area where the population density does not exceed 500 persons per square mile out to 20 miles from the reactor, an applicant can demonstrate compliance with 10 CFR 100.21(h) by siting a nuclear reactor in a location where the population density does not exceed 500 persons per square mile out to a distance equal to twice the distance at which a hypothetical individual could receive a calculated total effective dose equivalent of 1 rem over a period of 1 month from the release of radionuclides following postulated accidents.

In addition, proposed Revision 4 restructures RG 4.7 to remove repetition found in Revision 3 by consolidating materials from the Discussion section and the two tables in Revision 3 of the RG into Section C, Staff Regulatory Guidance. To improve clarity and cohesiveness each topic in Section C was structured to list (1) relevant statutes and regulations, (2) related guidance, and (3) considerations, regulatory experience, and staff position.
The staff is also issuing for public comment a draft regulatory analysis (ADAMS Accession No. ML23123A095). The staff developed a regulatory analysis to assess the value of issuing or revising a regulatory guide as well as alternative courses of action.
As noted in the Federal Register on December 9, 2022 (87 FR 75671), this document is being published in the Proposed Rules section of the Federal Register to comply with publication requirements under 1 CFR chapter I.
III. Backfitting, Forward Fitting, and Issue Finality Issuance of this DG does not constitute backfitting as defined in 10 CFR 50.109, Backfitting, and as described in NRC Management Directive (MD) 8.4, Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests, would not affect the issue finality of any approval issued under 10 CFR part 52; and would not constitute forward fitting as that term is defined and described in MD 8.4.
If finalized, this regulatory guide will not apply to any construction permits, operating licenses, early site permits, limited work authorizations issued under 10 CFR 50.10, or combined licenses, for which the NRC issued a final environmental impact statement (EIS) preceded by a draft EIS under 10 CFR 51.76 or 51.75, any of which were issued by the NRC prior to issuance of the final regulatory guide. The NRC has already completed its siting determination for those construction permits, operating licenses, early site permits, limited work authorizations, and combined licenses.
5
Therefore, no further NRC regulatory action on siting will occur for those licenses, permits, and authorizations, for which the guidance in the regulatory guide would be relevant.
The methods described in this proposed RG will be used in evaluating applications for construction permits, early site permits, combined operating licenses and limited work authorizations, which includes information under 10 CFR 51.49(b) or (f),
with respect to compliance with applicable regulations governing the siting of new nuclear power plants and testing facilities, unless the applicant proposes an acceptable alternative method for complying with those regulations. Methods that differ from those described in this proposed RG may be deemed acceptable if the applicant provides sufficient basis and information for the NRC staff to verify that the proposed alternative complies with the applicable NRC regulations.
IV. Submitting Suggestions for Improvement of Regulatory Guides A member of the public may, at any time, submit suggestions to the NRC for improvement of existing RGs or for the development of new RGs. Suggestions can be submitted on the NRCs public website at https://www.nrc.gov/reading-rm/doc-collections/reg-guides/contactus.html. Suggestions will be considered in future updates and enhancements to the Regulatory Guide series.
Dated: October 13, 2023.
For the Nuclear Regulatory Commission.
