Our Mission

  • The NRC licenses and regulates the Nations civilian use of radioactive materials to provide reasonable assurance of adequate protection of public health and safety and to promote the common defense and security and protect the environment.

5 Some Nuclear Facts 99 nuclear power plants supply about 20 percent of the electricity in the U.S.

Nuclear materials are used in medicine for diagnosis and cancer treatment.

Nuclear materials are widely used in industry, such as in density gauges, flow measurement devices, radiography devices, and irradiators.
