How do pressurized water reactors work
WebOct 5, 2010 · The nuclear power cycle uses water in three major ways: extracting and processing uranium fuel, producing electricity, and controlling wastes and risks. Electricity generation Nuclear reactors generating electricity in the United States fall into two main categories: boiling water reactors (BWRs) and pressurized water reactors (PWRs). WebNov 25, 2024 · Pressurized Water Reactors are known as "PWRs." They keep water under pressure so that it heats but does not boil. Water from the reactor and the water that is turned into steam are in separate pipes and never mix. (Click for Larger Version) View an Animated Image of a Pressurized Reactor . Boiling Water Reactors are known as "BWRs."

WebSep 19, 2024 · Light Water Reactor technology development by Argonne National Laboratory. The knowledge gained from the experiments conducted with these reactors formed the technical basis for the designs of the commercial light water reactors currently used throughout the world for electric power generation. Nuclear Engineering Division 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.
