SUPPLEMENTARY INFORMATION:

I. Discussion

The NRC is issuing a revision to an existing 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 1 of RG 1.199 was issued for public comment with a temporary identification of Draft Regulatory Guide, DG-1284. The revision addresses changes in the codes and standards endorsed by Revision 0 of the guide. The revised codes and standards endorsed by Revision 1 include: (1) Appendix D, “Anchoring to Concrete,” of American Concrete Institute (ACI) 349-13, “Code Requirements for Nuclear Safety-Related Concrete Structures and Commentary,” (2) ACI 355.2-07, “Qualification of Post-Installed Mechanical Anchors in Concrete and Commentary,” and (3) American Society for Testing and Materials (ASTM) E488/E488M-15, “Standard Test Methods for Strength of Anchors in Concrete Elements.”

II. Additional Information

The NRC published a notice of the availability of DG-1284 in the Federal Register on April 22, 2019 (84 FR 16699) for a 60-day public comment period. The public comment period closed on June 21, 2019 and there were no public comments on the guide.

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

This regulatory guide provides guidance on standards for anchoring components and structural supports in concrete for nuclear power plants licensed under 10 CFR parts 50 and 52. The issuance of this regulatory guide does not constitute backfitting as defined in 10 CFR 50.109, “Backfitting,” and as described in NRC Management Directive 8.4, “Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests,” or affect issue finality of any approval issued under 10 CFR part 52, “Licenses, Certificates, and Approvals for Nuclear Power Plants,” because, as explained in this regulatory guide, licensees are not required to comply with the positions set forth in this regulatory guide.

Dated: April 3, 2020.
