تعريف nuclear reactor في الإنجليزية الإنجليزية القاموس.: Any device in which a controlled chain reaction is maintained for the purpose of creating heat (for power generation) or for creating neutrons and other fission products for experimental, medical or other purposes; A structure in which a fission chain reaction can be maintained and controlled It usually contains fuel, coolant, moderator, control absorbers and safety devices and is most often surrounded by a concrete biological shield to absorb neutron and gamma ray emmision; An apparatus in which the nuclear fission chain can be initiated, maintained, and controlled so that energy is released at a specific rate The reactor apparatus includes fissionable material (fuel) such as uranium or plutonium; fertile material; moderating material (unless it is a fast reactor); a heavy-walled pressure vessel; shielding to protect personnel; provision for heat removal; and control elements and instrumentation Designs of nuclear reactors currently in use or under development include; A device in which a nuclear fission chain reaction can be initiated, sustained, and controlled to generate heat or to produce useful radiation; A nuclear reactor is a machine which is used to produce nuclear energy or the place where this machine and other related machinery and equipment is kept. They shut down the nuclear reactor for safety reasons. Any of several devices in which a chain reaction is initiated and controlled, with the resulting heat typically used for power generation and the neutrons and fission products used for military, experimental, and medical purposes. Also called atomic reactor. a large machine that produces nuclear energy, especially as a means of producing electricity. Device that can initiate and control a self-sustaining series of nuclear-fission reactions. Neutrons released in one fission reaction may strike other heavy nuclei, causing them to fission. The rate of this chain reaction is controlled by introducing materials, usually in the form of rods, that readily absorb neutrons. Typically, control rods made of cadmium or boron are gradually inserted into the core if the series of fissions begins to proceed at too great a rate, which could lead to meltdown of the core. The heat released by fission is removed from the reactor core by a coolant circulated through the core. Some of the thermal energy in the coolant is used to heat water and convert it to high-pressure steam. This steam drives a turbine, and the turbine's mechanical energy is then converted into electricity by means of a generator. Besides providing a valuable source of electric power for commercial use, nuclear reactors also serve to propel certain types of military surface vessels, submarines, and some unmanned spacecraft. Another major application of reactors is the production of radioactive isotopes that are used extensively in scientific research, medical therapy, and industry; A device in which a nuclear fission chain reaction can be initiated, maintained, and controlled; (physics) any of several kinds of apparatus that maintain and control a nuclear reaction for the production of energy or artificial elements; An apparatus in which nuclear fission may be sustained in a self supporting chain reaction Commonly called reactor Formerly called pile; A device containing fissionable material in sufficient quantity and suitable arrangement to maintain a controlled, self-sustaining nuclear chain reaction; 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; atomic reactor, mechanism for the production of radio-active energy; A mechanism fueled by fissionable materials in a controlled nuclear chain reaction that releases heat, which can be used for civil purposes to generate electricity Since reactors also produce fissionable material (e g plutonium) in the irradiated fuel, they may be used as a source of fissile material for weapons Nuclear reactors fall into three general categories: power reactors, production reactors (for weapons), and research reactors; a place to convert uranium into usable energy through the fission process; a chamber designed to perform a nuclear reaction such as neutron bombardment; an apparatus in which nuclear fission may be initiated, maintained, and controlled to produce energy, conduct research, or produce fissile material for nuclear explosives; means an apparatus, other than an atomic weapon, designed or used to sustain nuclear fission in a self-supporting chain reaction; A heat balance device, in which the heat is provided by controlled fission of radioactive isotopes; 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 a fission chain reaction can be initiated, maintained and controlled Nuclear reactors are used in the power industry to produce steam for electricity; 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 the controlled fission of certain substances is used to produce new substances and energy; The structure which contains the nuclear process
nuclear reactor core: That part of a nuclear reactor which contains the fuel components that are undergoing nuclear reactions
nuclear reactor cores: plural form of nuclear reactor core
