What is nuclear energy? The science of nuclear power



Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei as energy is released.

For example, the nucleus of a uranium-235 atom, when hit by a neutron, splits into a barium nucleus and a krypton nucleus and two or three neutrons. These extra neutrons hit other surrounding uranium-235 atoms, which also split and create extra neutrons in a multiplication effect, causing a chain reaction to start in a fraction of a second.

With every reaction, energy is released in the form of heat and radiation. The heat can be converted into electricity in a nuclear power plant, similar to how heat from fossil fuels such as coal, gas and oil is used to generate electricity.
