Nuclear power is created through the process of nuclear fission, this involves splitting a large nucleus into two smaller nuclei with the release of kinetic energy and gamma radiation. The atoms that are usually used in the process of nuclear power are uranium 235 or plutonium 239. When a neutron with energy hits uranium 235, it becomes unstable and splits into two smaller nuclei such as barium and krypton whilst also releasing kinetic energy in the form of heat and also two or three neutrons that collide again with other atoms causing a chain reaction. This can be seen by the nuclear fission equation of uranium 235 . This chain reaction is controlled by the ‘control rods’ in the reactor vessel that absorb the neutrons. Before uranium 235
