2020-3-31 · Thorium vs Uranium – Energy Release per Fission. In general, the nuclear fission results in the release of enormous quantities of energy. The amount of energy depends strongly on the nucleus to be fissioned and also depends strongly on the kinetic energy of an incident neutron.

Thanks for asking Akhil. When you consider radioactive decay of nuclei, half life plays a very important role. Uranium ore is 99.28% U-238 (I'd believe you on that), which is radioactive but with a very big half life of 4.5 x 10^9 years. Which m...

2020-3-29 · Uranium is a silvery-gray metallic weakly radioactive chemical element.It has the chemical symbol U and atomic number 92. The most common isotopes in natural uranium are 238 U (99.27%) and 235 U (0.72%). All uranium isotopes present in natural uranium are radioactive and fissionable, and 235 U is fissile (will support a neutron-mediated chain reaction). Uranium, thorium, and potassium are the ...
