Definitions for "Pressurized Water Reactor"
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.
