The Nuclear Regulatory Commission licenses and regulates civilian use of nuclear energy to protect public health and safety and the environment.

Organizational Chart

The Nuclear Regulatory Commission (NRC) was established as an independent regulatory agency under the provisions of the Energy Reorganization Act of 1974 (42 U.S.C. 5801 et seq.) and Executive Order 11834 of January 15, 1975. All licensing and related regulatory functions formerly assigned to the Atomic Energy Commission were transferred to the Nuclear Regulatory Commission.

Five Commissioners whom the President appoints and Senate confirms for 5-year terms govern the NRC. The President appoints one of them to be the Commission's Chair and official spokesperson.

The NRC's major program components are the Office of Nuclear Reactor Regulation, the Office of New Reactors, the Office of Nuclear Material Safety and Safeguards, the Office of Federal and State Materials and Environmental Management Programs, and the Office of Nuclear Regulatory Research. Headquartered in Rockville, Maryland, the NRC has four regional offices.

The Commission ensures that nuclear materials and facilities for civilian use are managed in a manner consistent with public health and safety, environmental quality, national security, and antitrust laws. The NRC centers most of its efforts on regulating the use of nuclear energy to generate electric power.


The NRC is primarily responsible for the following functions: licensing the construction, operation, and closure of nuclear reactors and other nuclear facilities, such as nuclear fuel cycle facilities, low-level radioactive waste disposal sites under NRC jurisdiction, the geologic repository for high-level radioactive waste, and nonpower test and research reactors; licensing the possession, use, processing, handling, and export of nuclear material; licensing the operators of nuclear power and nonpower test and research reactors; inspecting licensed facilities and activities; conducting the U.S. Government research program on light-water reactor safety; developing and implementing rules and regulations that govern licensed nuclear activities; investigating nuclear incidents and allegations concerning any matter regulated by the Commission; maintaining the NRC Incident Response Program; collecting, analyzing, and disseminating information on the operational safety of commercial nuclear power reactors and certain nonreactor activities; developing working relationships with the States regarding reactor operations and the regulation of nuclear material; and assuring that adequate regulatory programs are maintained by States exercising regulatory control over certain nuclear materials located within their borders.

Sources of Information

Active Regulatory Guides

Regulatory guides provide guidance to licensees and applicants for implementing parts of the Commission's regulations, techniques used by NRC staff to evaluate problems or postulated accidents, and data needed by NRC staff to review applications for permits or licenses. Regulatory guides are issued in 10 broad divisions: antitrust and financial review, environmental and siting, fuels and materials facilities, materials and plant protection, occupational health, power reactors, products, research and test reactors, transportation, and general. Active regulatory guides may be downloaded from the NRC's online library.

Business Opportunities

The NRC awards contracts to commercial firms, nonprofit organizations, and universities. The agency buys products and services, including technical assistance and research in nuclear fields, information technology, facility management, and administrative support.

Draft Regulatory Guides

The NRC issues regulatory guides in draft form to solicit public comment and participation in developing regulatory positions. Draft regulatory guides have not received complete staff review, and, therefore, they do not represent official NRC staff positions. The public may comment on draft guides and other documents issued in draft form online. NRC staff considers all comments received during the public comment period. Draft regulatory guides may be downloaded from the NRC's online library.


To carry out its mission, the NRC relies heavily on engineers, scientists, and security professionals.
