US6991731B2 - Treatment process for removing radioactive ...

The liquid effluent from solvent extraction contains radioactive thorium Th-231 and Th-234. This invention uses an ion exchange process to remove and concentrate the thorium. The process is designed so that the thorium remains on the ion exchange column until it decays to uranium and protactinium. These decay products are subsequently replaced by additional thorium.

A Thorium Future? | American Scientist

It is conceivable that a nation or revolutionary group might expel IAEA observers, stop a liquid-fluoride thorium reactor (LFTR) and attempt to remove U-233. Skilled engineers would need to modify the radioactive reactor's fluorination equipment to separate uranium from the fuel salt.

Options For Removing Uranium & Thorium From Zircon …

• Natural zircon contains uranium and thorium in varying quantities and from an environmental aspect this is problematic • The industry accepted standard is U+Th <500 ppm • High brightness is a marketing advantage • Removal of uranium and thorium achieves the production of a premium product • Sell a zircon sand to the ceramic market

A sand cleaning machine, beach cleaner, or (colloquially) sandboni is a vehicle that drags a raking or sifting device over beach sand to remove,

Uranium- and Thorium-Doped Graphene for Efficient Oxygen ...

Uranium and thorium compounds are broadly used in chemical catalysis. However, to the best of our knowledge, no previous study has compared the electrocatalytic activity of uranium and thorium. In this respect, the differences between thorium and uranium are related to their chemical behavior. ... (5%) solutions to remove sulfate ions and then ...

Recovery of uranium, thorium and rare earth from ...

This paper addresses the development of a process to recovery uranium, thorium and rare earth elements from an industrial residue, with a subsequent removal of U and Th from the liquor generated. Sulfuric acid digestion followed by water leaching was found …

Thorium processing |

Uranium-233 and thorium are coextracted into a tributyl phosphate solution, which is then contacted with an aluminum nitrate solution to remove traces of accompanying fission products. Dilute nitric acid is used to preferentially remove thorium from the scrubbed organic phase.

How Uranium Becomes Nuclear Fuel - YouTube

May 02, 2015· "The U.S. Nuclear Regulatory Commission (NRC) regulates uranium recovery facilities that mill uranium; fuel cycle facilities that convert, enrich, and fabricate it into fuel for use in nuclear ...

Uranium - Wikipedia

Uranium-234, which is a member of the uranium series (the decay chain of uranium-238), decays to lead-206 through a series of relatively short-lived isotopes. Uranium-233 is made from thorium-232 by neutron bombardment, usually in a nuclear reactor, and 233 U is also fissile.

Thorium vs Uranium - Nuclear Power

Thorium vs Uranium – Energy Release per Fission. In general, the nuclear fission results in the release of enormous quantities of energy. The amount of energy depends strongly on the nucleus to be fissioned and also depends strongly on the kinetic energy of an incident neutron.

Uranium-232 - Wikipedia

Uranium-232 (232 92 U, 232 U, U-232) is an isotope of uranium. It has a half-life of 68.9 years and is a side product in the thorium cycle.It has been cited as an obstacle to nuclear proliferation using 233 U as the fissile material, because the intense gamma radiation emitted by 208 Tl (a daughter of 232 U, produced relatively quickly) makes the 233 U contaminated with it more difficult to ...

Exemption Guidance: Uranium and thorium

Uranium or thorium compounds are substances or articles (including uranium and thorium metals) in which the U-235 concentration is no more than 0.72% by mass in the case of uranium, and the thorium is in its isotopic proportions found in nature.


A process is presented for separating uranium from thorium wherein the ratio of thorium to uranium is between 100 to 10,000. According to the invention the thoriumuranium mixture is dissolved in nitric acid, and the solution is prepared so as to obtain the desired concentration within a critical ...
