Uranium and the majority of the other heavy elementsâ¦ are formed by stellar nucleosynthesis in novas and supernovas. Heavy elements from the various sources in our galaxy combined with the mass of hydrogen that was the beginning of the formation our solar system around five billion years ago.
Uranium found in nature consists largely of two isotopes, U-235 and U-238. The production of energy in nuclear reactors is from the 'fission' or splitting of the U-235 atoms, a process which releases energy in the form of heat. U-235 is the main fissile isotope of uranium.
