A 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 … Meer weergeven Just as conventional thermal power stations generate electricity by harnessing the thermal energy released from burning fossil fuels, nuclear reactors convert the energy released by controlled nuclear fission into … Meer weergeven Classifications By type of nuclear reaction All commercial power reactors are based on nuclear fission. They generally use uranium and its product plutonium as nuclear fuel, though a thorium fuel cycle is also possible. … Meer weergeven Serious, though rare, nuclear and radiation accidents have occurred. These include the Windscale fire (October 1957), the SL-1 accident … Meer weergeven The neutron was discovered in 1932 by British physicist James Chadwick. The concept of a nuclear chain reaction brought about by nuclear reactions mediated by neutrons was first realized shortly thereafter, by Hungarian scientist Leó Szilárd, … Meer weergeven Thermal reactors generally depend on refined and enriched uranium. Some nuclear reactors can operate with a mixture of … Meer weergeven Nuclear safety covers the actions taken to prevent nuclear and radiation accidents and incidents or to limit their consequences. … Meer weergeven Almost two billion years ago a series of self-sustaining nuclear fission "reactors" self-assembled in the area now known as Oklo in Gabon, West Africa. The conditions at that place and time allowed a natural nuclear fission to occur with circumstances that are … Meer weergeven WebThe Fission Process In the nucleus of each atom of uranium-235 (U-235) are 92 protons and 143 neutrons, for a total of 235.
