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 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 NRC'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 Fiber-Optic Cables, Connections, and Optical Fiber Splices for Use in Safety Systems for Production and Utilization Facilities,” is temporarily identified by its task number, DG-1427, and describes an approach that is acceptable to the NRC staff for use in complying with NRC regulations that address the environmental qualification of fiber-optic cables, connections, and optical fiber splices in safety systems in production and utilization facilities.
DG-1427 is newly proposed Revision 0 of RG 1.257 and endorses, subject to the conditions described in Section C of this DG, the Institute of Electrical and Electronics Engineers Standard 1682-2023, which provides methods, directions, and documentation for the qualification of fiber optic cables, connections, and optical fiber splices in safety systems of production and utilization facilities.
The staff is also issuing for public comment a draft regulatory analysis (ADAMS Accession No. ML24201A069). The staff developed a regulatory analysis to assess the value of issuing or revising an RG 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 chapter I of title 1 of the Code of Federal Regulations (CFR).
III. Backfitting, Forward Fitting, and Issue Finality
Issuance of DG-1427, if finalized, would 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”; does not affect issue finality of any approval issued under 10 CFR part 52, “Licenses, Certificates, and Approvals for Nuclear Power Plants”; nor constitute forward fitting as defined in MD 8.4, because, as explained in this DG, licensees would not be required to comply with the positions set forth in this DG.
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.
