| 释义 | reactor (once / 2137 pages) n A reactor is where a nuclear reaction is controlled, making it possible to create energy or any number of artificial elements. Reactor these days almost always refers to a nuclear reactor, where atomic fission of uranium or plutonium creates the heat used to make steam to generate electricity. Originally, though, reactor meant a vessel in which chemical processes were made to generate useful products such as nylon and artificial sweetener. These reactors are still used in chemical manufacturing plants. WORD FAMILYreactor: reactors USAGE EXAMPLESA quarter century after China fired up its first nuclear reactor, the country is poised to become the world’s biggest producer of nuclear power. Wall Street Journal(Dec 29, 2016) You’re the reactor, doing the majority of your work in silence. New York Times(Dec 21, 2016) The reactor operated until 1963 and President Lyndon Johnson dedicated it as a Registered National Historic Landmark three years later.
