Nuclear Power Generator: A nuclear reactor or nuclear power generator is a kind of furnace for carrying out the controlled fission of a radioactive material like U235 for producing power.
The core of the nuclear reactor produces heat through nuclear fission. Heavy water at high pressure takes heat away from the core. In the heat exchanger, the heavy water inside the reactor gives up its heat to water outside the reactor, which boils to form steam. The steam is taken away to drive turbines that make electricity.
