A reactor type which uses ordinary (light) water at high pressure both as coolant and moderator. It is the most widely used type of reactor for producing electricity.
A light-water nuclear reactor in which heat is transferred from the reactor core to a heat exchanger via water kept under high pressure, so that high temperatures can be maintained in the primary system without boiling the water. Steam is generated in a secondary system.
A nuclear reactor which uses superheated water to transfer heat energy.
a nuclear reactor that uses water as a coolant and moderator; the steam produced can drive a steam turbine
a nuclear power reactor in which the cooling water is kept under high pressure and not allowed to boil until the water passes into the turbine units.
A nuclear reactor system in which reactor coolant water is kept under high pressure to keep it from boiling into steam.
A reactor in which the heat from the nuclear core is transferred to a heat exchanger under constant pressure to achieve a high water temperature without boiling. A secondary circuit produces steam for the generators.
A light water reactor in which the water used as a moderator is kept under pressure preventing it from boiling.
a reactor in which water, heated by nuclear energy is kept at high pressure to prevent the water from boiling. Steam is then generated in a secondary loop.
A reactor designed in which water flowing through the reactor is heated by nuclear energy but is kept at high pressure to keep the water from boiling. This heated water then transfers its heat to a secondary water system that boils into steam to drive the turbine.
Pressurized water reactors (PWRs) (also VVER) are generation II nuclear power reactors that use water under high pressure as coolant and neutron moderator. The primary coolant loop is kept under high pressure to prevent the water from boiling, hence the name. PWRs are one of the most common types of reactors and are widely used all over the world.
