Thorium Reactors: An Improvement Over Uranium?

Thorium and uranium reactors use different fission reactions, which means the reactions have different products and properties. Uranium reactors use uranium-235 as their fissile fuel, as well as the plutonium-239 that is produced from the uranium-238 that is also present in the fuel, and this reaction produces enough neutrons to perpetuate the ...

SOME INVESTIGATIONS ON THE URANIUM-THORIUM-CARBON …

The dicarbides of uranium and thorium were prepared by sintering mixtures of the elemental powders at 1500 and 1800 deg C, respectively. Uranium dicarbide is stable in air at room temperature; in pellet form as prepared it breaks down in dry air between 200 and 300 deg C and in moist argon between 300 and 400 deg C. Thorium dicarbide decomposes rapidly at room temperature by reaction with ...

Uranium–thorium dating - Wikipedia

Uranium–thorium dating, also called thorium-230 dating, uranium-series disequilibrium dating or uranium-series dating, is a radiometric dating technique established in the 1960s which has been used since the 1970s to determine the age of calcium carbonate materials such as speleothem or coral. Unlike other commonly used radiometric dating techniques such as rubidium–strontium or uranium ...

Thorium Reactor - Thorium Power Plant

Thorium reactors are based on the thorium fuel cycle and use thorium 232 as a fertile material.During the fuel burning, thorium 232 transforms into a fissile uranium 233.Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as thorium 231), which are insufficient to initiate and sustain nuclear chain reaction.

Thorium - World Nuclear Association

Uranium, Radium, and Thorium Uranium, radium, and thorium occur in three natural decay series, headed by uranium-238, thorium-232, and uranium-235, respectively. In nature, the radionuclides in these three series are approximately in a state of secular equilibrium, in which the activities of all radionuclides within each series are nearly equal.

Thorium - HPS Chapters

Thorium is also found in the minerals thorite (thorium silicate) and thorianite (mixed thorium and uranium oxides). The isotope thorium-230, a decay product of uranium-238, is found in uranium deposits as well as in uranium mill tailings. How Is It Used? The principal use of thorium has been in the preparation of the Welsbach mantle for ...

Uranium and thorium | Geoscience Australia

Uranium and thorium are not stable. They break down in a process called radioactive decay. More than 99% of natural uranium exists in a form (isotope) called uranium-238 while more than 99% of natural thorium exists as thorium-232. These metals decay very slowly eventually to form lead.
