development program, and his determination to double the total federal commitment to energy research and development for fiscal year 1975, were in line with the recommen- dations made by the Commission chairman. The Ray report also supported the President’s recommendation to establish an Energy Research and Development Administration.(41) Reactor Safety In December 1973 the Commission announced new requirements for the performance of the emergency core cooling systems (ECCS) installed in light-water-cooled powerreactors. Such systems provided the capability for emergency removal of heat from the reactor core in the event of a loss of the normal reactor coolant water. The Commission's action concluded a two-year public rulemaking hearing which had served as a foca! point for public discussion of opposing viewpoints on the safety of nuclear powerplants. Six months of hearing sessions, between January 27, 1972 and July 25, 1973, had produced a voluminous transcript, a clear witness to the complexity of the technical issues involved in nuclear safety. A constant advocate of the public’s right to know and fully understand the possible dangers of radiation, the Joint Committee on Atomic Energy had also held a hearing in early 1973 on the safety of nuclear powerplants. Clearly the handwriting on the wail was spelling out the numbered days of the AEC in 1973. Although nuclear power constituted a significant part of the answer to the Nation's need for additional sources of energy, it was by no means the only answer as had been predicted in the early decades of the Commission's existence. Summary When President Ford signed the Energy Reorganization Act of 1974 on October 11, the Atomic Energy Commission’s twenty-eight year stewardship of the Nation’s nuclear energy program came to an end. On January 19, 1975, the Commission's research and development responsibilities were assumed by the Energy Research and Development Administration, and the regulatory and licensing functions by the Nuclear Regulatory Commission. Six thousand, three hundred and twenty Commission employees went to ERDA while one thousand nine hundred and seventy former regulatory personnel becamepart of the new Nuclear Regulatory Commission. In the preceding twenty-eight years the Atomic Energy Commission had accomplished a large partion of the mission established by the Congress in 1946. First, through its weapon laboratories and production contractors, it had developed and stockpiled an array of sophisticated nuclear weapons which for nearly three decades had served as an important element in national defense. Also in the area of defense, the Commission had supported the development of nuclear propulsion reactors which made possible the creation of a fleet of reliable nuclear submarines and surface ships. Although for many years military related programs commanded the major portion of the budget, the Commission had initiated and supported extensive research in the nuclear sciences. The research contract and the national laboratory had become keyinstruments in the widespread development and application of nuciear technology for scientific, medical, and industrial purposes. Through participation in the International Atomic Energy Agency,international conferences and bilateral agreements, the United States shared the new technologywith other nations. The congressional mandate of 1946 also called for the use of atomic energy in a way that would strengthen free competition in private enterprise. Although the severe restrictions of the 1946 Act made atomic energy virtually a government monopoly, the Commission in less than a decade advanced nuclear technology to the point where industrial participation was feasible, and then encouraged the passage of new legislation in 1954 which made a nuclear industry possible. By the eariy 1970’s nuclear poweroffered a promising option for meeting national and world energy needs. in carrying out the Congressional mandate of 1946, the Atomic Energy Commission essentially worked its way out of existence. After concentrating on defense commitments in the early years, the Commission then focused on the development of a viable nuclear industry, only to come underfire in the late 1960's and 1970's for being in the position of regulating the same industry it helped to create. This difficulty had been foreseen in 1961 when the functions of the agency were divided between the General Managerand the Director of Regulation. Then in 1963 the two functions were physically separated by being housed in different geographical locations. Finally, the legal separation of the developmental and requlatory functions, requested in 1973 by the Commission itself, was accomplished by the Energy Reorganization Act of 1974. The regulatory and licensing responsibilities became the exclusive focus of a new agency headed by a five-member board, the Nuclear Regulatory Commission, while the developmental functions were placed under a single administrator in a second agency, the Energy Research and Development Administration. In the preceding decade the Atomic Energy Commission had lost muchofits privileged status with Congress and the American public. The exclusive monopoly ard the mantle of secrecy had been largely removed, and no longer did atomic energy seemingly provide the perfect formula for both military defense and civilian energy needs. Regulatory restrictions and environmental concerns were a large part of the reason for the demise of the AEC, but more important was the recagnition that a_ single technology should not be the exclusive focus of one agency. The energy crisis would now require the coordination of all major energy programs in a new research and development agency, whose primary purpose would be to assist the Nation in achieving energy independence. Asa legacy to the new agency, the Atomic Energy Commission passed on its unique production facilities, its valuable network of national {aboratories, and the proven technological skills, resourcefulness, and experience of its personnel. Three years later the Energy Research and Development Administration, like the Atomic Energy Commission before it, became part of an even larger organiza- tion. On October 1, 1977 Congress created a cabinet-level Department of Energy to coordinate Federal energy policies and programs.
