NRC's guidance documents are reviewed on a periodic basis to determine whether they require an update. You may review the update status of these guidance documents by going to the Guidance Document Revisions section of this site.

Regulatory guides (RGs) are issued in ten divisions and are intended to aid licensees in implementing regulations. The guides most applicable to licensing operators are in:

Division 1, Power Reactors

The following guides in these divisions are the ones most relevant to licensed operators.

  • RG 1.8 - Qualification and Training of Personnel for Nuclear Power Plants
  • RG 1.114 - Guidance to Operators at the Controls and to Senior Operators in the Control Room of a Nuclear Power Unit
  • RG 1.134 - Medical Evaluation of Licensed Personnel for Nuclear Power Plants
  • RG 1.149 - Nuclear Power Plant Simulation Facilities for Use in Operator License Examinations.
  • RG 1.206 - Combined License Applications for Nuclear Power Plant.

Each regulatory guide is listed by division number; title; date issued, and revisions, if applicable. A guide available at this site has an underscored number. Draft regulatory guides are listed separately. Many regulatory guides are available in NRC's Agency Document Access and Management System (ADAMS).
