here is my process for making thorium from the magnetron of a microwave oven. Keep in mind that thorium is radioactive and should be handled with care.

Has the processing of Pa^233 actually been demonstrated ...

Has the processing of Pa^233 actually been demonstrated? One of the criticisms of Thorium reactors is the Protactinium problem. For background, when 232 Th -> 233 Th, it quickly (~20min) decays to 233 Pa, which will decay to 233 U. However, that second decay takes ~27 days. During this time, the 233 Pa is a neutron absorber, meaning it's a ...

Uranium And Thorium Distribution In India - UPSC

Uranium and Thorium are the main atomic minerals to which may be added i.e., beryllium, lithium, and zirconium. Thorium is derived from monazite which contains 10 percent thoria and 0.3 percent urania. The other mineral carrying thorium is thorianite. The nuclear power plants in India use nuclear fuel processed in three stages.

12. Thorium can power Lunar ore processing, ore furnaces, machining, manufacturing, and assembly of more Thorium LFTR reactors – as well as building space craft. (This obviates the need to take everything to the Moon from Earth.) I would advocate the design of robotics solely for lunar use (which may or may not be made on Earth).

Economic analysis of thorium extraction from monazite ...

Thorium (232 Th) is four times more abundant than uranium in nature and has become a new important source of energy in the future.This is due to the ability of thorium to undergo the bombardment of neutron to produce uranium-233 (233 U).The aim of this study is to investigate the production cost of thorium oxide (ThO 2) resulted from the thorium extraction process.

Thorium Reactors: An Improvement Over Uranium?

Thorium has its share of risks as a nuclear fuel, and it isn't obvious that it would be a significant improvement over uranium in terms of safety, proliferation prevention, or cost. If an easy-to-switch-off accelerator is used to supply neutrons, and a molten salt reactor is used, then some (though not all) of the main failure modes of uranium ...

Thorium Extraction Methods - UC Homepages

when thorium-232 absorbs a neutron, it transmutes to uranium-238, a viable nuclear fuel. Originally, thorium extraction was a process that was high in energy and waste, using large amounts of heat and solvent. Modern science is working to produce thorium more efficiently. In this paper, several common thorium extraction processes are discussed.

Thorium - World Nuclear Association

Thorium is much more abundant in nature than uranium. Thorium can be used as a nuclear fuel through breeding to uranium-233 (U-233). When this thorium fuel cycle is used, much less plutonium and other transuranic elements are produced, compared with uranium fuel cycles. Several thorium-fuelled reactor concepts are under consideration.
