WebDec 18, 2024 · Thorium has no isotopes that readily fission to produce energy. So thorium is not usable as a fuel directly, but is instead a fertile nucleus that can be converted to uranium in a reactor. Only after conversion to uranium does thorium become useful as a nuclear fuel. WebThorium. The only gaseous product in the thorium decay series is thoron, which has a very short half-life (56 s). It can be used to determine 220 Rn, and also its parent, 232 Th. Thorium is determined by comparison with a standard, but because of the short half-life of 220 Rn, decay correction must be made. Naturally occurring thorium cannot be ...

WebJan 10, 2024 · A thorium reactor is a form of nuclear energy, proposed for use as a molten salt reactor. It is fueled by the uranium-233 isotope that is taken from the element … WebThe irradiated fuel can then be unloaded from the reactor, the U-233 separated from the thorium, and fed back into another reactor as part of a closed fuel cycle. Alternatively, thorium can be incorporated into the fuel salt of a molten salt reactor (MSR) and the U-233 burned as it is bred. (See information page on MSRs .)
