Transcription: A nuclear reactor produces heat through nuclear fission in which atomic nuclei break apart, releasing large amounts of energy. In the core of the reactor, a self-sustaining nuclear chain reaction takes place. Control rods are raised or lowered to absorb neutrons and control the reaction and the amount of heat produced. The most common type of nuclear reactor is the pressurized water reactor. It is known as a double loop system because it uses two circuits of water. The first circuit, or primary loop, pumps water heated by the reactor core through coils in a heat exchanger. The water remains li ...
