Energy sustainability Nuclear energy Nuclear energy is released through nuclear fission. Nuclear fission is when an atom splits and releases neutrons after absorbing a neutron. All nuclear power is generated from Uranium, which is a pure metal. Nuclear fission expained When atoms split, energy is released and then converted to a more easier form to use. Uranium-235, an isotope of Uranium (same number of protons, but different numbers of neutrons, meaning they have varying masses), is most commonly used in this proccess, because it requires less energy to split then other isotopes like Uranium-238. Basically, inside a nuclear reactor, free neutrons collide with the Uranium atoms. Uranium-235 is the minority as it only makes up 0.7% of natural Uranium. When a neutron collides with an atom of Uranium-235, it would join the nucleus of the atom, making it Uranium-236. After gaining the neutron, the atom will split, releasing energy as it does that. The products of the reaction are Krypton-92, Barium-141 and 3 free neutrons. Going in a chain reaction, the new neutrons would then collide with the other Uranium atoms causing them to split as well. The reaction has been written underneath. 1 neutron + 1 Uranium-235 → Barium-141 + Krypton-92 + 3 neutrons * In order to slow down the proccess and control the heat produced, control rods made of boron are lowered into the reactor to absorb the neutrons. The conversion to Electrical power 1. The energy from nuclear fission is
