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.

Revision 0 of RG 1.164 (ADAMS Accession No. ML17041A206) was issued with a temporary identification of Draft Regulatory Guide, DG-1292 (ADAMS Accession No. ML15313A425). This RG proposes new guidance that describes methods that the NRC staff considers acceptable in meeting regulatory requirements for dedication of commercial-grade items used in nuclear power plants.

II. Additional Information

The NRC published a notice of the availability of DG-1292 in the Federal Register on July 8, 2016 (81 FR 44670), for a 60-day public comment period. The public comment period closed on September 6, 2016. Public comments on DG-1292 and the staff responses to the public comments are available under ADAMS under Accession No. ML17041A202.

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 and Issue Finality

Regulatory Guide 1.164, Revision 0, describes a method that the staff of the NRC considers acceptable for dedication of commercial-grade items for use in nuclear power plants. Issuance of this RG does not constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule) and is not otherwise be inconsistent with the issue finality provisions in 10 CFR part 52. As discussed in the “Implementation” section of this RG, the NRC has no current intention to impose this RG on holders of current operating licenses or combined licenses.
