 Nuclear reactor - Wikipedia   (Site not responding. Last check: 2007-10-08)
A nuclear reactor is an apparatus in which nuclear fission chain reactions are initiated, controlled, and sustained at a contained rate.
Although the majority of nuclear reactors exist to produce useful energy for the generation of electricity, some are used for research, the production of radioactive isotopes for medical and industrial use, and/or the production of plutonium for nuclear weapons.
Thermal (slow) reactors are composed of fuel (fissionable material), moderating materials to slow neutrons to low velocities (to prevent capture by U238), heavy-walled pressure vessels to house reactor components, shielding to protect personnel, systems to conduct heat away from the reactor, and instrumentation for monitoring and controlling the reactor's systems.
