## II. Additional Information

The NRC is issuing for public comment a DG in the NRC's “Regulatory Guide” series. This series was developed to describe methods that are acceptable to the NRC staff for implementing specific parts of the agency's 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.

The DG, entitled “Qualification of Class 1E Connection Assemblies for Production and Utilization Facilities,” is temporarily identified by its task number, DG-1400.

                    Production and utilization facilities licensed under part 50 of title 10 of the                     *Code of Federal Regulations*                     (10 CFR), “Domestic Licensing of Production and Utilization Facilities” and 10 CFR part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” are required to demonstrate and document for Class 1E electrical connection assemblies and environmental seals in combination with cables or wires as assemblies for the ability of this equipment to perform safety functions under applicable service conditions, including design-basis events. Proposed Revision 2 provides updated information on state-of-the-art environmental qualification methodologies for production and utilization facilities.                

The staff is also issuing for public comment a draft regulatory analysis (ADAMS Accession No. ML21288A561). The staff developed a regulatory analysis to assess the value of issuing or revising a regulatory guide as well as alternative courses of action.

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

Issuance of DG-1400, if finalized, would not constitute backfitting as that term is 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 constitute forward fitting as that term is defined and described in MD 8.4; and would not affect issue finality of any approval issued under 10 CFR part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants.” As explained in DG-1400, applicants and licensees are not required to comply with the positions set forth in DG-1400.

## 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 NRC's 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.
