and split (nuclear fission). Uranium, used at a nuclear power station, is an element with such atoms. Fission In a nuclear power station atoms are split during a process called nuclear fission which takes place in the reactor core. The nuclear fission process releases energy in the form of heat. The heat is used to heat and convert water to steam.

In general, conversion is a process in which the uranium is converted to a form suitable either for fuel fabrication or enrichment. A minority of nuclear power plants do not require enriched uranium and for these power plants, the yellow cake (U 3 O 8) is converted to uranium dioxide (UO 2) at the conversion plant.
