How Boiling Water Reactors Work Published Mar 25, 2009 Updated Mar 25, 2011 The crisis at the Fukushima Daiichi nuclear plant in Japan has brought renewed interest in the design and safety features of nuclear reactors, particularly boiling water reactors (BWRs), the type found at … Maps, tools, and resources related to energy disruptions and infrastructure. Pressurized-water reactor (PWR) A common nuclear power reactor design in which very pure water is heated to a very high temperature by fission, kept under high pressure (to prevent it from boiling), and converted to steam by a steam generator (rather than by boiling, as in a boiling-water reactor).The resulting steam is used to drive turbines, which activate generators to produce electrical power. SMRs have simple, compact designs that can be assembled in a factory and transported by train or truck to the power plant site. [3] They make use of light water (ordinary water, as opposed to heavy water) as their coolant and neutron moderator. Of the 96 nuclear power reactors operating in the United States, 64 are pressurized-water reactors (as of January 1, 2020).
