The United States Atomic Energy Commission (AEC) was an agency of the United States government established after World War II by Congress to foster and control the peace time development of atomic science and technology. President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective from January 1, 1947.
An increasing number of critics during the 1960s charged that the AEC's regulations were insufficiently rigorous in several important areas, including radiation protection standards, nuclear reactor safety, plant siting, and environmental protection. By 1974, the AEC's regulatory programs had come under such strong attack that Congress decided to abolish the agency. The agency was abolished by the Energy Reorganization Act of 1974, which assigned its functions to two new agencies: the Energy Research and Development Administration and the Nuclear Regulatory Commission.[1]

In creating the AEC, Congress declared that atomic energy should be employed not only in the form of nuclear weapons for the nation's defense, but also to promote world peace, improve the public welfare and strengthen free competition in private enterprise. At the same time, the McMahon Act which created the AEC also gave it unprecedented powers of regulation over the entire field of nuclear science and technology. It furthermore explicitly prevented technology transfer between the United States and other countries, and required FBI investigations for all scientists or industrial contractors who wished to have access to any AEC controlled nuclear information. The signing was the culmination of long months of intensive debate among politicians, military planners and atomic scientists over the fate of this new energy source and the means by which it would be regulated. President Truman appointed David Lilienthal as the first Chairman of the AEC.
Congress gave the new civilian Commission extraordinary power and considerable independence to carry out its mission. To provide the Commission exceptional freedom in hiring scientists and professionals, Commission employees were exempt from the Civil Service system. Because of the need for great security, all production facilities and nuclear reactors would be government-owned, while all technical information and research results would be under Commission control. The National Laboratory system was established from the facilities created under the Manhattan Project. Argonne National Laboratory was one of the first laboratories authorized under this legislation as a contractor-operated facility dedicated to fulfilling the new Commission's mission.
The AEC was furthermore in charge of developing the United States' nuclear arsenal, taking over these responsibilities from the wartime Manhattan Project. Over the course of its first decade, the AEC oversaw the operation of Los Alamos Scientific Laboratory, devoted primarily to weapons development, and, in 1952, the establishment of a second weapons laboratory in California (the Lawrence Livermore National Laboratory). It also implemented the "crash" program to develop the hydrogen bomb, and played key roles in the prosecution of the Rosenbergs for espionage. It began a program of regular nuclear testing both in the Pacific Proving Grounds and at the continental Nevada Test Site. While it also supported much basic research, the vast majority of its early budget was devoted to atomic weapons development and production.
Within the AEC, high-level scientific and technical advice was provided by the General Advisory Committee, originally headed by J. Robert Oppenheimer. In its early years, the GAC provided a number of controversial decisions, notably its decision against building the hydrogen bomb in 1949. The AEC's connections with the armed services was facilitated by a Military Liaison Committee. Congressional oversight over the AEC was exercised by the Joint Committee on Atomic Energy, which had considerable power in influencing AEC decisions and policy.
The AEC's far-reaching powers and control over subject matter which had far-reaching social, public health, and military implications made it an extremely controversial organization. One of the drafters of the McMahon Act, James R. Newman, famously concluded that the bill made "the field of atomic energy [an] island of socialism in the midst of a free-enterprise economy".
Before the Nuclear Regulatory Commission (NRC) was created, nuclear regulation was the responsibility of the AEC, which Congress first established in the Atomic Energy Act of 1946. Eight years later, Congress replaced that law with the Atomic Energy Act Amendments of 1954, which for the first time made the development of commercial nuclear power possible, and resolved a number of other outstanding problems in implementing the first Atomic Energy Act. The act assigned the AEC the functions of both encouraging the use of nuclear power and regulating its safety. The AEC's regulatory programs sought to ensure public health and safety from the hazards of nuclear power without imposing excessive requirements that would inhibit the growth of the industry. This was a difficult goal to achieve, especially in a new industry, and within a short time the AEC's programs stirred considerable controversy. Stephanie Cooke has written that:
"the AEC had become an oligarchy controlling all facets of the military and civilian sides of nuclear energy, promoting them and at the same time attempting to regulate them, and it had fallen down on the regulatory side ... a growing legion of critics saw too many inbuilt conflicts of interest".[2]
An increasing number of critics during the 1960s charged that the AEC's regulations were insufficiently rigorous in several important areas, including radiation protection standards, nuclear reactor safety, plant siting, and environmental protection.
In 1973, the AEC predicted that, by the turn of the century, one thousand reactors would be producing electricity for homes and businesses across the United States. But after 1973, reactor orders declined sharply as electricity demand fell and construction costs rose. Many orders and partially completed plants were cancelled.[3]
By 1974, the AEC's regulatory programs had come under such strong attack that Congress decided to abolish the agency. Supporters and critics of nuclear power agreed that the promotional and regulatory duties of the AEC should be assigned to different agencies. The Energy Reorganization Act of 1974 put the regulatory functions of the AEC into the new NRC, which began operations on January 19, 1975 and placed the promotional functions within the Energy Research and Development Administration, which was later incorporated into the United States Department of Energy.
