- Nuclear reactor - Wikipedia
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction They are used for commercial electricity, marine propulsion, weapons production and research Fissile nuclei (primarily uranium-235 or plutonium-239) absorb single neutrons and split, releasing energy and multiple neutrons, which can induce further fission
- NUCLEAR 101: How Does a Nuclear Reactor Work?
Learn how boiling and pressurized light-water reactors work Nuclear reactors are the heart of a nuclear power plant They contain and control nuclear chain reactions that produce heat through a physical process called fission That heat is used to make steam that spins a turbine to create electricity
- Nuclear Essentials - World Nuclear Association
Nuclear reactors are, fundamentally, large kettles, which are used to heat water to produce enormous amounts of low-carbon electricity They come in different sizes and shapes, and can be powered by a variety of different fuels
- Nuclear reactor: what it is, what it is used for and its . . .
A nuclear reactor (or atomic reactor) is a facility capable of converting nuclear energy into thermal energy The reactors have the capacity to initiate, control and maintain the nuclear chain reactions that occur in the core of this facility
- Nuclear reactor | Definition, History, Components | Britannica
nuclear reactor, any of a class of devices that can initiate and control a self-sustaining series of nuclear fission s Nuclear reactors are used as research tools, as systems for producing radioactive isotope s, and most prominently as energy sources for nuclear power plants
- What is a nuclear reactor? - What is nuclear?
A nuclear reactor is a system that contains and controls sustained nuclear chain reactions Reactors are used for generating electricity, moving aircraft carriers and submarines, producing medical isotopes for imaging and cancer treatment, and for conducting research
- How a Nuclear Reactor Works - Nuclear Energy Institute
Nuclear reactors are designed to sustain an ongoing chain reaction of fission; the reactors operating in the U S today are filled with a specially designed, solid uranium fuel and surrounded by water, which facilitates the process When the reactor starts, uranium atoms will split, releasing neutrons and heat
