  2. Nuclear reactor - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reactor

    A fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing so, it bypasses the Carnot cycle and can achieve efficiencies of up to 90% instead of 40–45% attainable by efficient turbine-driven thermal reactors.

    These types are not exclusive, for example a VVER is a PWR. It may not even always be clear what is included in a type: In some contexts an ABWR is a type of BWR, but in most contexts it is not. See also Category:Nuclear power stations and its subcategories for details of particular power reactors.

  9. Nuclear power - Wikipedia

    en.wikipedia.org/wiki/Nuclear_power

    A fission nuclear power plant is generally composed of: a nuclear reactor, in which the nuclear reactions generating heat take place; a cooling system, which removes the heat from inside the reactor; a steam turbine, which transforms the heat into mechanical energy; an electric generator, which transforms the mechanical energy into electrical ...
