This element itself is not fissile but when used in a Liquid Fluoride Thorium Reactor (LFTR), it can potentially be a source of nuclear power that is cheaper, cleaner, and safer compared to current uranium power plants.
Get MoreUranium-233 can be recovered and purified from neutron-irradiated thorium reactor fuels through the thorium extraction, or Thorex, process, which employs tributyl phosphate extraction chemistry. Irradiated fuel, containing either thorium metal or oxide, is dissolved in nitric acid containing a small amount of fluoride ion.

Get MoreThorium has a safer and stable reactor processing. It's a molten-salt process which uses a less pressurized reactor. If reactor power fails, it will automatically shut down orderly. Thorium does not use a water solution, so it cannot boil over or explode. Instead, a molten-salt solution is used.
Get MoreThorium is a naturally occurring, mildly radioactive element. To use it in a nuclear reactor, thorium must absorb neutrons, a process that eventually converts it to an artificial isotope of uranium, uranium-233. U-233 is fissile, and when it absorbs a neutron it generally fissions, releasing two or three neutrons plus a million times more heat ...

Get MoreUranium is cheap as dirt. Thorium requires either (a) molten salt reactors or (b) extensive fuel reprocessing. (a) MSR:s are still in the viability phase, with many technological quirks and material compatibility issues to work out (b) fuel reprocessing is expensive business so only countries with large nuclear fleets with reactors that can utilize MOX fuel or Th-Pu fuel should undertake it.
Get MoreIn essence, a molten salt reactor [ MSR] is a vessel that contains a hot liquid salt which a nuclear reaction takes place. The salt consists of the nuclear fuel, and several other compounds that optimize the reaction, the heat transfer and the stability of the salt. This means the salt mixture is both the fuel and the coolant.
