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). Several hundred PWRs are used for marine propulsion in aircraft carriers, nuclear submarines and ice breakers. In the US, they were originally designed at the Oak Ridge National Laboratory for use as a nuclear submarine power plant with a fully operational submarine power plant located at the Idaho National Laboratory. Follow-on work was conducted by Westinghouse Bettis Atomic Po…
WebNov 25, 2024 · Pressurized Water Reactors are known as "PWRs." They keep water under pressure so that it heats but does not boil.
