Portsmouth Gaseous Diffusion Plant is a facility located in Scioto Township, Pike County, Ohio, just south of Piketon, Ohio, that previously produced enriched uranium, including highly enriched weapons-grade uranium, for the United States Atomic Energy Commission (AEC), the U.S. nuclear weapons program and Navy nuclear propulsion; in later years, it produced low-enriched uranium for fuel for ...
Yellowcake (also called urania) is a type of powdered uranium concentrate obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared by various extraction and ...
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 ...
For natural uranium fuel, fissile component starts at 0.7% 235 U concentration in natural uranium. At discharge, total fissile component is still 0.5% (0.2% 235 U, 0.3% fissile 239 Pu, 241 Pu ). Fuel is discharged not because fissile material is fully used-up, but because the neutron-absorbing fission products have built up and the fuel becomes ...
Uranium dioxide is minimally soluable in water, but after oxidation it can be converted to uranium trioxide or another uranium(VI) compound which is much more soluble. Uranium dioxide (UO 2 ) can be oxidised to an oxygen rich hyperstoichiometric oxide (UO 2+x ) which can be further oxidised to U 4 O 9 , U 3 O 7 , U 3 O 8 and UO 3 .2H 2 O.
The cooled oxide fuel is chopped up in the Shear Cell and the fuel dissolved in nitric acid. It is chemically conditioned before passing to the chemical separation plant. Pulsed columns (designated HA/HS) are used to initially separate the majority of the uranium and plutonium from the fission products by transferring them into the solvent ...
New deals just dropped, including our favorite digital picture frame, every Apple device you can think of, and a Barbie dreamhouse any kid would be thrilled to open Christmas morning.
Here uranium values were recovered from feed materials (i.e., ores, concentrates and residues) and were converted to concentrated uranium trioxide, also called orange salt. In addition to uranium, the Refinery was capable of extracting and purifying a number of different materials.
