Pressurized water reactors

Model of a PWR type nuclear power plant
A pressurized water reactors (for its initials in English PWR: Pressurized Water Reactor) is a type of nuclear reactor that uses water as coolant and neutron moderator.
In a PWR, the primary cooling circuit is pressurized to prevent water reaches its boiling point, hence the name of this type of reactors. The PWR is one of the most commonly used reactor types worldwide. There are over 230 type PWR reactors in use for power generation (the PWR typically produce between 900 and 1500 MWe), and several hundred more that are used for naval propulsion. The PWR was originally designed by the Bettis Atomic Power Laboratory to be used as a power plant in a nuclear submarine. Also, some small PWR have been used for heating in polar regions (see Army Nuclear Power Program).
