Web26 apr. 2016 · The majority of uranium in the fuel is uranium-238, but a small percentage (3-5%) is uranium-235. Uranium-235 can undergo nuclear fission, and is therefore the portion of the fuel we’re interested in. So what is nuclear fission? Put simply, it’s when an atom splits into two smaller atoms, releasing a lot of energy as it does so. Web10 apr. 2024 · Isotopes of Uranium. The most common isotopes of uranium are uranium-238 and uranium-235. Uranium-238: It is the most abundant isotope of uranium, accounting for over 99% of natural uranium.
