The pressurized water reactor (PWR) is a type of nuclear reactor used to the generate electricity and propel nuclear submarines and naval vessels. 16MPa). Pressurized Water Reactor Power Plant This material was, for a purpose to be used in a nuclear education, compiled comprehensively with a caution on appropriateness and neutrality of information, based on references of neutral organizations, suh as NRC, Wikipedia and ATOMICA, and vendors' information especially on advanced reactors.

They are cooled and moderated by high-pressure liquid water (e.g. In the end of this material, references are listed.
… Pressurized water reactors have advantages over the other light water reactors and earlier generation nuclear sites. Light water reactors of the Pressurized Water Reactor (PWR) and Boiling Water Reactor (BWR) type have performed very well over several decades. Pressurized water reactors (PWRs) constitute the large majority of all western nuclear power plants (ex- cepting the United Kingdom) and are one of three types of light water reactor (LWR), the other types being boiling water reactors (BWRs) and supercritical water re- actors (SCWRs). This high pressure is maintained by
The fuel is in the form of relatively small bundles of The fuel is in the form of relatively small bundles of fuel rods which are inserted into the pressure tubes. pressurized water reactor (PWR).
A PWR has fuel assemblies of 200-300 rods each, arranged vertically in the core, and a large reactor would have about 150-250 fuel assemblies with 80-100 tonnes of uranium. [1] One major advantage of this reactor is that it is easy to operate because less power is being produced as the heat increases. At this pressure water boils at approximately 350°C (662°F). They make use of light water (ordinary water, as opposed to heavy water ) as their coolant and neutron moderator . Pressurized water reactors use a reactor pressure vessel (RPV) to contain the nuclear fuel, moderator, control rods and coolant. However, in the United States without any action being taken, a number of reactors would come to the end of their license period and be shut down. Pressurized Water Reactor (PWR): It is a thermal reactor, using enriched uranium oxide, clad in zircalloy as fuel.
