# SUPPLEMENTARY INFORMATION:

## I. Discussion

The NRC is issuing a new guide in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public information regarding methods that are acceptable to the NRC staff for implementing specific parts of the agency's regulations, techniques that the NRC staff uses in evaluating specific issues or postulated events, and data that the NRC staff needs in its review of applications for permits and licenses.

RG 2.8 was issued with a temporary identification of Draft Regulatory Guide, DG-DG-2007 (ADAMS Accession No. ML21243A103).

## II. Additional Information

                    The NRC published a notice of the availability of DG-2007 in the                     **Federal Register**                     on November 23, 2021 (86 FR 66464) for a 30-day public comment period. The public comment period closed on December 23, 2021. Public comments on DG-2007 and the staff responses to the public comments are available under ADAMS under Accession No. ML22020A296.                

## III. Congressional Review Act

This RG is a rule as defined in the Congressional Review Act (5 U.S.C. 801-808). However, the Office of Management and Budget has not found it to be a major rule as defined in the Congressional Review Act.

## IV. Backfitting, Forward Fitting, and Issue Finality

                    The NRC staff may use this RG as a reference in its regulatory processes, such as licensing, inspection, or enforcement. However, the NRC staff does not intend to use the guidance in this RG to support NRC staff actions in a manner that would constitute backfitting as that term is defined in Section 50.109 of title 10 of the                     *Code of Federal Regulations*                     (10 CFR), “Backfitting,” and as described in NRC Management Directive (MD) 8.4, “Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests.” However, the backfitting provisions in 10 CFR 50.109, do not apply to Part 50 licensees other than power reactors. The regulatory basis for 10 CFR 50.109 was expressed solely in terms of nuclear power reactors. The NRC's Advanced Notice of Proposed Rulemaking, Policy Statement, Proposed Rules, and Final Rules for amendments to 10 CFR 50.109 in the 1980s involved only nuclear power reactors. As a result, the NRC has not applied 10 CFR 50.109 to research reactors, testing facilities, and other non-power facilities licensed under 10 CFR part 50 (                    *e.g.,*                     “Final Rule; Clarification of Physical Protection Requirements at Fixed Sites”). In a 2012 final rule concerning non-power reactors, the NRC stated, “The NRC has determined that the backfit provisions in 10 CFR 50.109 do not apply to test, research, or training reactors because the rulemaking record for 10 CFR 50.109 indicates that the Commission intended to apply this provision to only power reactors, and NRC practice has been consistent with this rulemaking record” (“Final Rule; Requirements for Fingerprint-Based Criminal History Records Checks for Individuals Seeking Unescorted Access to Non-Power Reactors”).                

## V. 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 NRC's public                           ( print page 10832)                        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.
