Equipment for carrying out controlled nuclear fission reactions, usually used to generate power
A device in which nuclear fission may be sustained and controlled in a self-supporting nuclear reaction. The varieties are many, but all incorporate certain features, including fissionable material or fuel, a moderating material (unless the reactor is operated on fast neutrons), a reflector to conserve escaping neutrons, provisions of removal of heat, measuring and controlling instruments, and protective devices. The reactor is the heart of a nuclear power plant. See; Light-Water Reactor, Pressurized-Water Reactor, Reactor.
A plant that produces energy by nuclear fission.
A device in which nuclear fission may be sustained and controlled in a self-supporting nuclear reaction. There are several varieties, but all incorporate certain features, such as fissionable material or fuel, a moderating material (to control the reaction), a reflector to conserve escaping neutrons, provisions for removal of heat, measuring and controlling instruments, and protective devices
A device in which a controlled, self-sustained nuclear chain reaction can be maintained and generated heat removed. Types include power reactors, research and test reactors, and fissile material production reactors (for fissile material).
A device containing fissionable material in sufficient quantity and suitable arrangement to maintain a controlled, self-sustaining nuclear chain reaction.
(physics) any of several kinds of apparatus that maintain and control a nuclear reaction for the production of energy or artificial elements
a device containing quantities of fissionable materials in which a chain reaction can be sustained on a constant basis
a device to control this release of energy
a furnace, fueled by radioactive material
an apparatus in which nuclear fission chain reactions are initiated, controlled, and sustained at a contained rate
an apparatus in which nuclearfission chain reactions are initiated, controlled, and sustained ata steady rate
a unit constructed to enclose all the equipment and material necessary to produce and control the process of nuclear fission
A heat balance device, in which the heat is provided by controlled fission of radioactive isotopes.
A device in which a fission chain reaction is maintained, used for the irradiation of materials or the generation of electricity.
A device in which a nuclear fission reaction is maintained and controlled for the purpose of generating heat, which boils water, to spin a turbine, to drive a generator, to produce electricity.
A device in which a fission chain reaction can be initiated, maintained and controlled. Nuclear reactors are used in the power industry to produce steam for electricity.
(1) A device that produces a sustained, controlled fission chain reaction. (2) A device in which a sustained fission reaction can be maintained. The core is made of a fissile material such as uranium enriched in the isotope 235U. It is usually surrounded by water which moderates neutrons and removes heat from the core. Synonym: reactor. Related to nuclear power plant. Related to research reactor.
An apparatus in which nuclear fission may be sustained in a self-supporting chain reaction. A reactor includes fissionable material (fuel) such as uranium or plutonium, and moderating material (except fast reactors), and usually includes a reflector to conserve escaping neutrons, provision for heat removal, and measuring and control elements. The terms "pile" and "reactor" have been used interchangeably, with reactor now becoming more common. These terms usually are applied only to systems in which the reaction proceeds at a controlled rate, but they have also been applied to bombs.
Nuclear reactor is an assembly of fissionable material (uranium-235 or plutonium-239) designed to produce a sustained and controllable chain reaction for the generation of electric power. The essential components of a nuclear reactor are: 1. The core, metal rods containing enough fissionable material to maintain a chain reaction at the necessary power level (as much as 50 t of uranium may be required). 2. A source of neutrons to initiate the reaction (such as a mixture of polonium and beryllium) 3. A moderator to reduce the energy of fast neutrons for more efficient fission (material such as graphite, beryllium, heavy water, and light water are used) 4. A coolant to remove the fission-generated heat (water, sodium, helium, and nitrogen may be used) 5. A control system such as rods of boron or cadmium that have high capture cross sections (to absorbs neutrons) 6. Adequate shielding, remote-control equipment, and appropriate instrumentation are essential for personnel safety and efficient operation.
A device in which a fission chain reaction can be initiated, maintained, and controlled. Its essential components are fissionable fuel, moderator, shielding, control rods, and coolant.
A system in which controlled nuclear fisson reactions generate heat energy on a large scale, which is subsequently converted into electrical energy.
a device in which atoms are split at a controlled rate.
a device that sustains a controlled nuclear fission chain reaction. (from U.S. Department of Energy website http://www.em.doe.gov/). **Note: There are 103 active nuclear reactors in the U.S.
A device in which a nuclear fission chain reaction occurs under controlled conditions so that the heat yield can be harnessed or the neutron beams utilised. All commercial reactors are thermal reactors, using a moderator to slow down the neutrons.
A device in which nuclear fission can be sustained in a self-supporting chain reaction involving neutrons. In thermal reactors, fission is brought about by thermal neutrons.
an apparatus in which nuclear fission may be initiated, maintained, and controlled to produce energy, conduct research, or produce fissile material for nuclear explosives.
is the part of the nuclear plant where the uranium atoms are split to produce heat and make the steam that turns the turbines.
An apparatus in which nuclear fission may be sustained in a self supporting chain reaction. Commonly called reactor. Formerly called pile.
A nuclear reactor is a device in which nuclear chain reactions are initiated, controlled, and sustained at a steady rate (as opposed to a nuclear bomb, in which the chain reaction occurs in a fraction of a second and is completely uncontrolled).
