How do pressurized water reactors work

WebJan 30, 2024 · A pressurized water reactor (PWR) is a common design of a nuclear reactor. In a PWR, water functions as a coolant and as a moderator. A moderator slows down the neutrons, because slower moving neutrons are better at causing fission to occur. A moderator is usually water; however, graphite and heavy water can also be used. WebPressurized water reactors (PWRs) make up the majority of all Western nuclear power plants. In a PWR, as depicted in Fig. 1, water is pumped under high pressure to the reactor core where it is heated by the energy generated by the fission of atoms. ...
