Lakeview Mining Company
The Lakeview Mining Company was a Uranium mining#Heap leaching, uranium reduction plant north of Lakeview, Oregon, Lakeview, Lake County, Oregon, Lake County, Oregon. The mill began operating in February 1958 and operating until November 1960. The site covered ; of ore were processed, leaving behind large amounts of residual radioactive material. These were moved to an engineered disposal cell in 1986-1988. The plant was built in 1957-1958 for a cost of approximately $3 million, selling the yellow cake to United States Atomic Energy Commission, Atomic Energy Commission. The plant employed approximately 50 workers. Two successful mines were open in the area, Lucky Lass and White King, feeding the Lakeview plant. Seven raffinate ponds across were used for the uranium extraction process, and a uranium tailings pile existed. In 1961 Kerr-McGee purchased the site; it changed hands several times and by 1968 was owned by Atlantic Richfield (ARCO), which began radiation remediation. M ...

Uranium Mining
Uranium mining is the process of extraction of uranium ore from the ground. Over 50 thousand tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tons per year included Namibia, Niger, Russia, Uzbekistan, the United States, and China. Nearly all of the world's mined uranium is used to power nuclear power plants. Historically uranium was also used in applications such as uranium glass or ferrouranium but those applications have declined due to the radioactivity of uranium and are nowadays mostly supplied with a plentiful cheap supply of depleted uranium which is also used in uranium ammunition. In addition to being cheaper, depleted uranium is also less radioactive due to a lower content of short-lived and than natural uranium. Uranium is mined by in-situ leaching (57% of world production) or by conventional und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium Mill Tailings Radiation Control Act
The Uranium Mill Tailings Radiation Control Act (1978) is a United States environmental law that amended the Atomic Energy Act of 1954 and authorized the Environmental Protection Agency to establish health and environmental standards for the stabilization, restoration, and disposal of uranium mill waste. Title 1 of the Act required the EPA to set environmental protection standards consistent with the Resource Conservation and Recovery Act, including groundwater protection limits; the Department of Energy to implement EPA standards and provide perpetual care for some sites; and the Nuclear Regulatory Commission to review cleanups and license sites to states or the DOE for perpetual care. Title 1 established a uranium mill remedial action program jointly funded by the federal government and the state. Title 1 of the Act also designated 22 inactive uranium mill sites for remediation, resulting in the containment of 40 million cubic yards of low-level radioactive material in UMTRCA Tit ...

Radioactive Waste
Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity, intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding, and high-level waste (HLW), which is highly radioactive and hot due to decay heat, so requires cooling and shielding. In nuclear reprocessing plants about 96% of spent nuclear fuel is recycled back into uranium-based and mixed-oxide (MOX) fuels. The residual 4% is minor actinides and fission products the latter of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium Mines In The United States
Uranium is a chemical element with the Symbol (chemistry), symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive decay, radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordial nuclide, primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few Parts-per notation#Parts-per expressions, parts per million in soil, rock and water, and is commercially uranium mining, ext ...

Climax Uranium Mill
Climax Uranium Mill is a decommissioned uranium mill near Grand Junction, CO. The mill, which processed vanadium as well as uranium, was incorporated May 11, 1950. It was constructed on city-owned property next to the Colorado River which was once the Grand Junction sugar beet mill. Climax Uranium Company gutted the former sugar beet mill, removing any remaining equipment and stabilizing weak walls, and began uranium and vanadium milling operations. The mill soon grew to be 12 buildings large and processed 2 million tons of ore, mostly for the United States Atomic Energy Commission. The mill caused contamination in an aquifer directly beneath the surface of the site. Mill tailings were allowed to be taken for civilian and construction use in the city which led to many vicinity properties with elevated radiation levels. In 1970, the mill was decommissioned and most of the contaminated materials were brought to the Grand Junction Disposal Site. Some of the leftover tailings used in ...

Hunter's Hot Springs (Oregon)
Hunters Hot Springs (often stylized as Hunter's Hot Springs) are natural geothermal springs located in Lake County, Oregon, north of Lakeview. The springs are named after Harry Hunter, who bought the springs in 1923. The best known feature within the geothermal area is ''Old Perpetual'', which is Oregon's only continuously erupting geyser. The geyser was formed as a result of a well drilling attempt while Hunter was developing a health resort at the springs. Springs The hot springs were discovered in 1832 by trappers from the Hudson's Bay Company, who noted in their journal that the water was unbearably hot.Birkby, Jeff"Geyser (Hunter's) Hot Spring" ''Touring Washington and Oregon Hot Springs'', Globe Pequot Publishers, Guilford, Connecticut, 2002, p. 120.
