NRC's regulations are found in Chapter I of Title 10, "Energy," of the Code of Federal Regulations (10 CFR). Chapter I is divided into Parts 1 through 199. The following are the principal parts governing the nuclear power plant operators.
- Part 55 – Operators' Licenses
- Part 50 – Domestic Licensing of Production and Utilization Facilities
- Part 52 – Licenses, Certifications, and Approvals for Nuclear Power Plant
See also, information on all NRC Rules and Petitions.
The NRC welcomes Public Involvement in Rulemaking, and invites the public to comment on proposed rules and policies, licensing actions, and draft technical documents. We announce public comment opportunities in the Federal Register and on our Documents for Comment page.
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 Power Reactors (Division 1).
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).
