Regulatory Guide Update Program

The NRC is reviewing and prioritizing updates to its regulatory guides (RGs) based on anticipated need and to ensure complete, accurate, and current guidance. The NRC has categorized the RGs to be updated into four groups. The first group (Phase 1) represents RGs that the staff updated by March 2007 to support anticipated new reactor licensing activities. The staff prioritized the remaining RGs based on information from several sources. The staff plans to develop and publish the second group (Phase 2) by December 2008, and the third group (Phase 3) by December 2009, and the fourth group (Phase 4) by the end of CY 2010. All RGs have been categorized into one of the following groups:

1. Phase 1
2. Phase 2
3. Phase 3
4. Phase 4
5. Considered for Withdrawal
6. Not planned to be developed or revised by the end of CY 2010

Notes on Regulatory Guides

• A guide number is composed of the division number followed by a period and a sequential number in that division (e.g., 1.25). A guide is further identified by revision numbers, as appropriate, the date of issuance, and sometimes its ADAMS Accession Number (an "ML" number in parentheses).
• A draft regulatory guide presents guidance that is issued for public comment while being developed. Comments are considered before finalizing the guide. Some draft guides are proposed revisions of existing guides.
• A draft guide number is composed of DG followed by a hyphen, the division number, and a sequential number in that division (e.g., DG-1070). A draft is sometimes identified by its ADAMS Accession Number (an "ML" number in parentheses).
• A guide available at this site has an underscored number. (The footnote numbers in online versions may differ from the printed versions.)
• Each division lists the titles of all the regulatory guides and all the draft guides.
