Uranium stocks on the ASX: The Ultimate Guide
The active part of this energy process is the uranium-235 isotope which raw uranium contains in small amounts (0.71%), along with isotopes U-238 (99.28%) and traces of U-234 (0.0054%). Of these, only U-235 (143 neutrons + 92 protons) is fissile, meaning it can start a nuclear reaction and sustain it.
