nuclear reactor
Nuclear reactor (English: nuclear reactor) is a start, control and maintain the nuclear fission or nuclear fusion chain reaction device. In contrast to the uncontrolled chain reaction that occurs in the moment of the nuclear explosion, the rate of nuclear change can be precisely controlled in the reactor, and its energy can be released at a slower rate for people to use. Nuclear reactors have many uses, the most important use is to produce heat, to replace the other fuel heating water, produce steam power generation or drive aircraft carrier and other facilities to run. Some reactors are used to produce isotopes for medical and industrial purposes, or for the production of weapons grade plutonium. Some reactor runs only for research. All current commercial nuclear reactors are based on nuclear fission. Today, about 450 nuclear reactors are used in power generation in about 30 countries around the world. ...
