WebThe primary natural isotopes of uranium are uranium-235 (0.7 percent), which is fissile, and uranium-238 (99.3 percent), which is fissionable but not fissile. In nature, plutonium exists only in minute concentrations, so the fissile isotope plutonium-239 is made artificially in nuclear reactors from uranium-238. (See uranium processing.) 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. how many kilograms are 16 pounds
