Responsibility for the regulation and licensing of nuclear power, science and medicine in the United States and Canada, is shared by a number of federal, state and provincial agencies.

United States Nuclear Regulatory Commission (U.S.NRC) is an independent agency of the United States government tasked with protecting public health, safety and the environment related to nuclear energy. Created by Congress in 1974, NRC ensures and enforces safe use of radioactive materials for beneficial civilian purposes; and regulates commercial nuclear power plants and uses of nuclear materials in nuclear medicine.

Office of Nuclear Energy (NE) is an agency of the United States Department of Energy (DOE) which promotes nuclear power as a resource capable of meeting the United States’ energy, environmental, and national security needs by resolving technical and regulatory barriers through research, development, and demonstration.

National Nuclear Security Administration (NNSA) is a semi-autonomous agency within U.S. DOE responsible for enhancing national security through military application of nuclear science. Created by Congress in 2000, NNSA: maintains and enhances safety, security, and effectiveness of U.S. nuclear weapons stockpile without nuclear explosive testing; works to reduce global danger from weapons of mass destruction; provides U.S. Navy with safe and effective nuclear propulsion; and responds to nuclear and radiological emergencies in the U.S. and abroad.

Canadian Nuclear Safety Commission (CNSC-CCSN) is the federal regulator of nuclear power and materials in Canada. CNSC regulates: development, production and use of nuclear energy; health, safety and environment; possession and transport of nuclear substances; measures respecting the non-proliferation of nuclear weapons and nuclear explosive devices.

Atomic Energy of Canada Limited (AECL) is a federal Crown corporation responsible for enabling nuclear science and technology and managing the Government of Canada’s decommissioning and radioactive waste responsibilities.
