Fission reactions happen when the number of sub-atomic particles of an atom is reduced. Nuclear power plants take the element uranium and split it into lighter elements (such as cesium and rubidium), releasing energy in the process. Like fusion reactions in the sun, it takes very specific conditions to sustain a nuclear reaction like this.
