The Nuclear Energy Institute is the policy organization of the nuclear technologies industry, based in Washington, D.C.
NEI's mission is to promote the use and growth of nuclear energy through efficient operations and effective policy.
NEI accomplishes this by providing a unified industry voice before Congress, the executive branch, state, and local legislatures, and federal regulators, as well as international organizations and venues, on key policy issues.
NEI's members include companies that own or operate nuclear power plants, reactor designers and advanced technology companies, architect and engineering firms, fuel suppliers and service companies, consulting services and manufacturing companies, companies involved in nuclear medicine and nuclear industrial applications, radionuclide and radiopharmaceutical companies, universities and research laboratories, law firms, labor unions, and international electric utilities.
