ocr: FISSION REACTORS NUCLEAR FISSION reactor releases A energy inside a nuclear power Steam fed to is station. At the reactor's cent ter are rods turbine ofuranium-235, whose atoms break up in nuclear chain reactions. The Control reactions are increased by a moderator, rods usually made of graphite, andslowed Uranium down by control rods, usually made fuel rods ofboron or cadmium. The energy generated by a reactor is used to turn water into steam, which drives a turbine.
