text: Glossary chain reaction repeated fission caused when the neutrons released in fission bombard other atoms containment system (also, shield) a three-part structure of materials that protects the exterior of a nuclear fission reactor and operating personnel from the high temperatures, pressures, and radiation levels inside the reactor control rod material inserted into the fuel assembly that absorbs neutrons and can be raised or lowered to adjust the rate of a fission reaction critical mass amount of fissionable material that will support a self-sustaining (nuclear fission) chain reaction fissile (or fissionable) when a material is capable of sustaining a nuclear fission reaction fission splitting of a heavier nucleus into two or more lighter nuclei, usually accompanied by the conversion of mass into large amounts of energy fusion combination of very light nuclei into heavier nuclei, accompanied by the conversion of mass into large amounts of energy fusion reactor nuclear reactor in which fusion reactions of light nuclei are controlled nuclear fuel fissionable isotope present in sufficient quantities to provide a self-sustaining chain reaction in a nuclear reactor nuclear moderator substance that slows neutrons to a speed low enough to cause fission nuclear reactor environment that produces energy via nuclear fission in which the chain reaction is controlled and sustained without explosion nuclear transmutation conversion of one nuclide into another nuclide particle accelerator device that uses electric and magnetic fields to increase the kinetic energy of nuclei used in transmutation reactions reactor coolant assembly used to carry the heat produced by fission in a reactor to an external boiler and turbine where it is transformed into electricity subcritical mass amount of fissionable material that cannot sustain a chain reaction; less than a critical mass supercritical mass amount of material in which there is an increasing rate of fission transmutation reaction bombardment of one type of nuclei with other nuclei or neutrons transuranium element element with an atomic number greater than 92; these elements do not occur in nature
text: A reactor aims for a steady rate of fission over time, where the neutrons released by fission cause an equal number of fissions in other fissile atoms.
text: The course of a chain reaction is determined by the probability that a neutron released in fission will cause a subsequent fission.
text: Neutrons released in fission are initially fast (velocity about 109 cm/sec, or energy above 1 MeV), but fission in U-235 is most readily caused by slow neutrons (velocity about 105 cm/s, or energy about 0.02 eV).
text: U does not undergo fission by the neutrons released in fission, thermal neutrons can be captured by the nucleus to transmute the uranium into 239
