Bookmark or Share- Nuclear reactor - WikipediaA nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines.
- How does a nuclear reactor work - World Nuclear AssociationNuclear 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 | Definition, History, & Components | Britannicanuclear 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. Principles of operation. fission.
- Nuclear reactor - Fission, Fusion, Breeder | BritannicaMost of the world’s existing reactors are power reactors, providing the heat needed to turn turbine s that run electric-power generators. There are also numerous research reactors, and some navies of the world have submarines or surface ships driven by propulsion reactors.
- Nuclear power reactors, reactor types and technologies | IAEAHome. Topics. Nuclear technology and applications. Energy. Nuclear power reactors produce energy by initiating and controlling a sustained nuclear chain reaction. Currently, over 400 such reactors in 32 countries provide about 10 per cent of the world’s electricity.
