How does thorium react
WebNearly 100% of thorium found on Earth is thorium-232, which is only slightly radioactive because it has such a long half-life. (Uranium-235’s half-life is 700 million years, shorter by … 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 ...
