WebAbout 425 reactors globally, ranging in size from 30-1660MW, are water-cooled. There are two major types of water-cooled reactor: light water reactors (which use normal water) and heavy water reactors (which use a chemically distinct type of water). Light water is used as the primary coolant in a PWR. Water enters through the bottom of the reactor's core at about 548 K (275 °C; 527 °F) and is heated as it flows upwards through the reactor core to a temperature of about 588 K (315 °C; 599 °F). The water remains liquid despite the high temperature due to the high pressure in the primary coolant loop, usually around 155 bar (15.0 MPa 153 atm, 2,250 psi). The water in a PWR cannot exceed a temperature of 647 K (374 °C; 705 °F) o… on the edge watch full film cillian murphy
