Nuclear Reactors

Controlled Fission : A nuclear reactor operates by the controlled fission of 235 U. Fission occurs at a slow steady rate, rather than suddenly in a fraction of a second, as in a bomb. Fission produces heat, and this heat is used to generate electricity, in the same way that the heat of burning oil or coal generates electricity in a conventional power plant.

Nuclear reactor - Wikipedia

A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self-sustained nuclear chain reaction.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.
