I. Introduction

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 such as methods that are acceptable to the NRC staff for implementing specific parts of the agency's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.

The NRC issued Revision 1 of RG 1.184 with a temporary identification as Start Printed Page 64029Draft Regulatory Guide, DG-1271 in the Federal Register on February 14, 2012 (77 FR 8902), for a 60-day public comment period. The public comment period closed on April 16, 2012. Public comments on DG-1271 and the staff responses to the public comments are available in ADAMS under Accession No. ML13144A843.

Revision 1 of RG 1.184 describes a method that the NRC staff considers acceptable for use in complying with the NRC's regulations relating to the decommissioning process for nuclear power reactors. The revision takes advantage of the 13 years of decommissioning experience since the first issuance of RG 1.184 in July 2000, and decommissioning guidance documents released since then have been incorporated into the guide.

II. Congressional Review Act

This regulatory guide 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.

III. Backfitting and Issue Finality

Issuance of this final regulatory guide does not constitute backfitting as defined in 10 CFR 50.109 and is not otherwise inconsistent with the issue finality provisions in 10 CFR part 52. As discussed in the “Implementation” section of this regulatory guide, the NRC has no current intention to impose this regulatory guide on holders of current operating licenses or combined licenses.
