“United States Atomic Energy Commission”的意思、由来-开放百科全书

The United States Atomic Energy Commission, commonly known as the AEC, was an agency of the United States government established after World War II by U.S. Congress to foster and control the peacetime development of atomic science and technology.^[4]{{rp|91–102}} 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 on January 1, 1947.^[5] This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the atomic bomb.^[6]

During its initial establishment and subsequent operationalization, the AEC played a key role in the institutional development of Ecosystem ecology. Specifically, it provided crucial financial resources, allowing for ecological research to take place.^[7] Perhaps even more importantly, it enabled ecologists with a wide range of groundbreaking techniques for the completion of their research. In the late 1950s and early 1960s, the AEC also approved funding for numerous bioenvironmental projects in the arctic and subarctic regions. These projects were designed to examine the effects of nuclear energy upon the environment and were a part of the AEC's attempt at creating peaceful applications of atomic energy.^[8]{{rp|22–25}}

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 the U.S. Congress decided to abolish the AEC. The AEC 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.^[9] On August 4, 1977, President Jimmy Carter signed into law The Department of Energy Organization Act of 1977, which created the Department of Energy. The new agency assumed the responsibilities of the Federal Energy Administration (FEA), the Energy Research and Development Administration (ERDA), the Federal Power Commission (FPC), and various other Federal agencies.

History

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.^[10] 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.^[4] {{rp| 91–92}}

Congress gave the new civilian AEC extraordinary power and considerable independence to carry out its mission. To provide the AEC exceptional freedom in hiring its scientists and engineers, AEC employees were exempt from the civil service system. The AEC's first order of business was to inspect the scattered empire of atomic plants and laboratories to be inherited from the U.S. Army.^[6]{{page needed|date=August 2014}}

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 AEC 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 AEC's missions.{{citation needed|date=December 2011}} the Argonne was the first of the regional laboratories, to involve universities in the Chicago area. Others were the Clinton (CEW) labs and the Brookhaven National Laboratory in the Northeast, although a similar lab in Southern California did not eventuate.{{sfn|Nichols|1987|p=232}}

On 11 March 1948 Lilienthal and Kenneth Nichols were summoned to the White House where Truman told them "I know you two hate each other’s guts". He directed that "the primary objective of the AEC was to develop and produce atomic weapons", Nichols was appointed a major general and replaced Leslie Groves as chief of the Armed Forces Special Weapons Project (AFSWP), previously Lilienthal had opposed his appointment. Lilienthal was told to "forgo your desire to place a bottle of milk on every doorstop and get down to the business of producing atomic weapons. {{sfn|Nichols|1987|pp=257-259}} Nichols became General Manager of the AEC on 2 November 1953.{{sfn|Nichols|1987|p=299}}

The AEC was in charge of developing the U.S. nuclear arsenal, taking over these responsibilities from the wartime Manhattan Project. In its first decade, the AEC oversaw the operation of Los Alamos Scientific Laboratory, devoted primarily to weapons development, and in 1952, the creation of new second weapons laboratory in California, the Lawrence Livermore National Laboratory. The AEC also carried out the "crash program" to develop the hydrogen bomb (H-bomb), and the AEC played a key role in the prosecution of the Rosenbergs for espionage.

The AEC also began a program of regular nuclear weapons testing, both in the faraway Pacific Proving Grounds and at the Nevada Test Site in the western United States. While the AEC also supported much basic research, the vast majority of its early budget was devoted to nuclear weapons development and production.{{citation needed|date=December 2011}}

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 General Advisory Committee (GAC) made a number of controversial decisions, notably its decision against building the hydrogen bomb (H-bomb), announced in 1949. As a result, U.S. Senator Brien McMahon prompted the decision not to reappoint J. Robert Oppenheimer to the GAC when his six-year statutory term expired in 1952. David Lilienthal, the AEC chairman, agreed with Oppenheimer, and he also opposed "a crash program to build the hydrogen bomb ahead of any other nation." Then President Truman asked Lilienthal to leave the AEC, and he did so on February 15, 1950. Lilienthal had been one of the original members of the AEC who granted Dr. Oppenheimer nuclear security clearances in 1947.

With Oppenheimer and Lilienthal removed, President Truman announced his decision to develop and produce the hydrogen bomb. The first test firing of an experimental H-bomb ("Ivy Mike") was carried out in the Central Pacific on November 1, 1952, under President Truman. Furthermore, U.S. Navy Admiral Lewis. W. Strauss was appointed in 1953 by the new President Eisenhower as the Chairman of the AEC, to carry out the military development and production of the H-bomb.^[11]

Lilienthal wanted to give high priority to peaceful uses, especially with nuclear power plants. However, coal was still cheap, and the electric power industry was not interested. The first experimental nuclear power plant was started in Pennsylvania under President Eisenhower in 1954.^[12]

Regulations and experiments

The AEC was connected with the U.S. Department of Defense by a "Military Liaison Committee"'. The Joint Committee on Atomic Energy exercised congressional oversight over the AEC and had considerable power in influencing AEC decisions and policy.^[13]

The AEC's far-reaching powers and control over a 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".^[14]

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 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. {{citation needed|date=December 2011}} 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 a history of involvement in experiments involving radioactive iodine. In a 1949 operation called the "Green Run," the AEC released iodine-131 and xenon-133 to the atmosphere which contaminated a {{convert|500000|acre|km2|adj=on}} area containing three small towns near the Hanford site in Washington.^[16]{{rp||pages=130–131}} In 1953, the AEC ran several studies on the health effects of radioactive iodine in newborns and pregnant women at the University of Iowa. Also in 1953, the AEC sponsored a study to discover if radioactive iodine affected premature babies differently from full-term babies. In the experiment, researchers from Harper Hospital in Detroit orally administered iodine-131 to 65 premature and full-term infants who weighed from {{convert|2.1|to|5.5|lbs|kg}}.^[16]{{rp|132–134}} In another AEC study, researchers at the University of Nebraska College of Medicine fed iodine-131 to 28 healthy infants through a gastric tube to test the concentration of iodine in the infants' thyroid glands.^[16]{{rp|132–134}}

Public opinion and abolishment of the AEC

During the 1960s and early 1970s, the Atomic Energy Commission came under fire from opposition concerned with more fundamental ecological problems such as the pollution of air and water.^[17]{{rp|113}} Under the Nixon Administration, environmental consciousness grew exponentially and the first Earth Day was held on April 22, 1970.^[17]{{rp|113}} Along with rising environmental awareness came a growing suspicion of the AEC and public hostility for their projects increased. In the public eye, there was a strong association between nuclear power and nuclear weapons, and even though the AEC had made a push in the late 1960s, to portray their efforts as being geared toward peaceful uses of atomic energy, criticism of the agency grew. The AEC was chiefly held responsible for the health problems of people living near atmospheric test sites from the early 1960s, and there was a strong association of nuclear energy with the radioactive fallout from these tests.^[17]{{rp|115}} Around the same time, the AEC was also struggling with opposition to nuclear power plant siting as well as nuclear testing. An organized push was finally made to curb the power held by the AEC, and in 1970 the AEC was forced to prepare an Environmental impact statement (EIS) for a nuclear test in northwestern Colorado as part of the initial preparation for Project Rio Blanco.^[18]{{rp| 244}}

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.{{citation needed|date=January 2019}} However, after 1973, orders for nuclear reactors declined sharply as electricity demand fell and construction costs rose. Some partially-completed nuclear power plants in the U.S. were stricken, and many planned nuclear plants were canceled.^[15]{{rp|283}}{{better source|date=January 2019}}

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 transferred the regulatory functions of the AEC to the new Nuclear Regulatory Commission (NRC), which began operations on January 19, 1975. Promotional functions went to the Energy Research and Development Administration which was later incorporated into the United States Department of Energy.^[19]

Lasting through the mid-1970s, the AEC and the Manhattan Project carried out human radiation experiments. The government covered up most of these radiation mishaps until 1993, when President Bill Clinton ordered a change of policy. Nuclear radiation was known to be dangerous and deadly (from the atomic bombings of Hiroshima and Nagasaki in 1945), and the experiments were designed to ascertain the detailed effect of radiation on human health.^[27] In Nashville, pregnant women were given radioactive mixtures. In Cincinnati, some 200 patients were irradiated over a period of 15 years. In Chicago, 102 people received injections of strontium and cesium solutions. In Massachusetts, 74 schoolboys were fed oatmeal that contained radioactive substances. In all these cases, the subjects did not know what was going on and did not give informed consent.

With the exposure of these experiments in 1993, under the administration of President Bill Clinton. The resulting investigation was undertaken by the Advisory Committee on Human Radiation Experiments, and it uncovered much of the material included in The Plutonium Files.^[20]

Ecology

For many years, the AEC provided the most conspicuous example of the benefit of atomic age technologies to biology and medicine.^[21]{{rp|649–684}}

Shortly after the Atomic Energy Commission was established, its Division of Biology and Medicine began supporting diverse programs of research in the life sciences, mainly the fields of genetics, physiology, and ecology.^[7] Specifically concerning the AEC's relationship with the field of ecology, one of the first approved funding grants went to Eugene Odum in 1951.^[7] This grant sought to observe and document the effects of radiation emission on the environment from a recently built nuclear facility on the Savannah River in South Carolina. Odum, a professor at the University of Georgia, initially submitted a proposal requesting annual funding of $267,000, but the AEC rejected the proposal and instead offered to fund a $10,000 project to observe local animal populations and the effects of secondary succession on abandoned farmland around the nuclear plant.^[7]

In 1961, AEC chairman Glenn T. Seaborg established the Technical Analysis Branch (to be directed by Hal Hollister) to study the long-term biological and ecological effects of nuclear war.^[22] Throughout the early 1960s, this group of scientists conducted several studies to determine nuclear weapons' ecological consequences and their implications for human life. As a result, during the 1950s and 1960s, the U.S. government placed emphasis on the development and potential use of "clean" nuclear weapons to mitigate these effects.^[23]

In later years,{{when|date=May 2014}} the AEC began providing increased research opportunities to scientists by approving funding for ecological studies at various nuclear testing sites, most notably at Eniwetok, which was part of the Marshall Islands. Through their support of nuclear testing, the AEC gave ecologists a unique opportunity to study the effects of radiation on whole populations and entire ecological systems in the field.^[7] Prior to 1954, no one had investigated a complete ecosystem with the intent to measure its overall metabolism, but the AEC provided the means as well as the funding to do so. Ecological development was further spurred by environmental concerns about radioactive waste from nuclear energy and postwar atomic weapons production. In the 1950s, such concerns led the AEC to build a large ecology research group at their Oak Ridge National Laboratory, which was instrumental in the development of radioecology. A wide variety of research efforts in biology and medicine took place under the umbrella of the AEC at national laboratories and at some universities with agency sponsorship and funding.^[21]{{rp|649–684}} As a result of increased funding as well as the increased opportunities given to scientists and the field of ecology in general, a plethora of new techniques were developed which led to rapid growth and expansion of the field as a whole. One of these techniques afforded to ecologists involved the use of radiation, namely in ecological dating and to study the effects of stresses on the environment.^[7]

In 1969, the AEC's relationship with science and the environment was brought to the forefront of a growing public controversy that had been building since 1965. In search for an ideal location for a large-yield nuclear test, the AEC settled upon the island of Amchitka, part of the Aleutian Islands National Wildlife Refuge in Alaska.^[18]{{rp|246}} The main public concern was about their location choice, as there was a large colony of endangered sea otters in close proximity. To help diffuse the issue, the AEC sought a formal agreement with the Department of the Interior and the U.S. state of Alaska to help transplant the colony of sea otters to other former habitats along the West Coast.^[18]{{rp|247}}

Arctic ecology

The AEC played a role in expanding the field of arctic ecology. From 1959 to 1962, the Commission's interest in this type of research peaked. For the first time, extensive effort was placed by a national agency on funding bio-environmental research in the Arctic. Research took place at Cape Thompson on the northwest coast of Alaska, and was tied to an excavation proposal named Project Chariot.^[8]{{rp|22}} The excavation project was to involve a series of underground nuclear detonations that would create an artificial harbor, consisting of a channel and circular terminal basin, which would fill with water. This would have allowed for enhanced ecological research of the area in conjunction with any nuclear testing that might occur, as it essentially would have created a controlled environment where levels and patterns of radioactive fallout resulting from weapons testing could be measured.^[8]{{rp|23}} The proposal never went through, but it evidenced the AEC's interest in Arctic research and development.

The simplicity of biotic compositions and ecological processes in the arctic regions of the globe made ideal locations in which to pursue ecological research, especially since at the time there was minimal human modification of the landscape.^[8]{{rp|25}} All investigations conducted by the AEC produced new data from the Arctic, but few or none of them were supported solely on that basis.^[8]{{rp|25}} While the development of ecology and other sciences was not always the primary objective of the AEC, support was often given to research in these fields indirectly as an extension of their efforts for peaceful applications of nuclear energy.{{citation needed|date=May 2014}}

Reports

The AEC issued a large number of technical reports through their technical information service and other channels. These had many numbering schemes, often associated with the lab from which the report was issued. AEC report numbers included AEC-AECU (unclassified), AEC-AECD (declassified), AEC-BNL (Brookhaven National Lab), AEC-HASL (Health and Safety Laboratory), AEC-HW (Hanford Works), AEC-IDO (Idaho Operations Office), AEC-LA (Los Alamos), AEC-MDCC (Manhattan District), AEC-TID, and others. Today, these reports can be found in library collections that received government documents, through the National Technical Information Service (NTIS), and through public domain digitization projects such as HathiTrust.^[24]
