Uranium ore mined in the Arlit area (Agadez Region) is extracted as triuranium octoxide (U 3 O 8). The SOMAIR mine had uranium reserve of 14,000 tonnes (with U 3 O 8 @ 0.3%) as of 2011 and a production capacity of 2,700 tonnes per year. [11] [12] The COMINAK concession totaled 29,000 tonnes (U 3 O 8 @ 0.4%) and had a production capacity of ...
PUREX (plutonium uranium reduction extraction) is a chemical method used to purify fuel for nuclear reactors or nuclear weapons. [7] PUREX is the de facto standard aqueous nuclear reprocessing method for the recovery of uranium and plutonium from used nuclear fuel ( spent nuclear fuel , or irradiated nuclear fuel).
The first successful solvent extraction process for the recovery of pure uranium and plutonium was developed at ORNL in 1949. [7] The PUREX process is the current method of extraction. Separation plants were also constructed at Savannah River Site and a smaller plant at West Valley Reprocessing Plant which closed by 1972 because of its ...
During this time period, the facility processed 1,983.7 kilograms (4,373 lb) of plutonium and 625.7 metric tons (1,379,000 lb) of spent uranium. [4]: 10–12 Using the PUREX process, the plant was able to recover 1,926 kilograms (4,246 lb) of plutonium and 620 metric tons (1,370,000 lb) of uranium. Most of the recovered uranium was depleted or ...
The advanced reprocessing of spent nuclear fuel is a potential key to achieve a sustainable nuclear fuel cycle and to tackle the heavy burden of nuclear waste management. In particular, the development of such advanced reprocessing systems may save natural resources, reduce waste inventory and enhance the public acceptance of nuclear energy.
World uranium reserves in 2010. Uranium reserves are reserves of recoverable uranium, regardless of isotope, based on a set market price. The list given here is based on Uranium 2020: Resources, Production and Demand, a joint report by the OECD Nuclear Energy Agency and the International Atomic Energy Agency. [1] Figures are given in metric ...
Infrared absorption spectra of the two UF 6 isotopes at 300 and 80 K. Schematic of a stage of an isotope separation plant for uranium enrichment with laser. An infrared laser with a wavelength of approx. 16 μm radiates at a high repetition rate onto a UF6 carrier gas mixture, which flows supersonically out of a laval nozzle.
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.
