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?

Fact-check: Five claims about thorium made by Andrew Yang

WebThe ability to control the chain reaction is entirely due to the presence of the small proportion of delayed neutrons arising from fission (0.66% for U-235, 0.27% for U-233, 0.23% for Pu-239). Without these, any change in the critical balance of the chain reaction would lead to a virtually instantaneous and uncontrollable rise or fall in the ... 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 .) kevin paffrath wikipedia
