Organization & Functions
The NRC is headed by a five-member Commission. The President designates one member to serve as Chairman and official spokesperson. The Commission as a whole formulates policies and regulations governing nuclear reactor and materials safety, issues orders to licensees, and adjudicates legal matters brought before it. The Executive Director for Operations (EDO) carries out the policies and decisions of the Commission and directs the activities of the program offices.
The offices reporting to the EDO ensure that the commercial use of nuclear materials in the United States is safely conducted. As part of the regulatory process, the four regional offices conduct inspection, enforcement, and emergency response programs for licensees within their borders.
The NRC has an annual budget of about $1 billion and employs about 3,000 people located in five primary locations in the United States.

Inspector General
- Office of the Inspector General (OIG)
Due to the unforeseen defunding of the Council of Inspectors General on Integrity and Efficiency (CIGIE), the website for the NRC Office of the Inspector General—which CIGIE hosts—is not being supported and has, for now, been shut down. As a result, there is no access to the online portal through our website’s Hotline submission form. If you have a concern that you would like to report to the OIG, you may still do so in three ways by using:
- Please see online Hotline submission form;
- The Hotline phone number (800-233-3497); or,
- The Hotline email address (OIGHOTLINE.Resource@nrc.gov).
