Atomic Energy Commission (AEC), former U.S. government commission created by the Atomic Energy Act of 1946 and charged with the development and control of the U.S. atomic energy program following World War II. At the time, debate centered around the question of whether the commission should be predominantly military or civilian. The act provided for a five-member commission appointed by the President with the advice and consent of the Senate, as well as a military liaison committee which the AEC was directed to advise and consult with on all atomic energy matters that related to military applications. A civilian advisory committee to the AEC was also created and from 1946 to 1952 this committee was chaired by J. Robert Oppenheimer, who had directed the development of the atomic bomb but who opposed the manufacture of the hydrogen bomb. The AEC became the center of a nation-wide controversy in 1954 as a result of Oppenheimer's suspension (1953) as a consultant to the commission on the alleged grounds that he was a security risk.
The activities of the AEC included the production of fissionable materials, the manufacture and testing of nuclear weapons, the development of nuclear reactors for military and civilian use, and research in biological, medical, physical, and engineering sciences. Although the bulk of the AEC's work was in the field of atomic weaponry, it was also involved in projects relating to the peaceful uses of atomic energy (e.g., the development of atomic power plants for the production of electricity). The AEC was dissolved in 1974 and its responsibilities transferred to the Energy Research and Development Administration (these functions are now under the Department of Energy) and the Nuclear Regulatory Commission.
