Pressurized water reactors (PWRs) constitute the large majority of all Western nuclear power plants and are one of three types of light water reactor (LWR), the other types being boiling water reactors (BWRs) and supercritical water reactors (SCWRs). In a PWR, the primary coolant (water) is pumped under high pressure to the reactor core where it i...

(from the article `nuclear reactor`) As noted above, LWRs are power reactors that are cooled and moderated with ordinary water. There are two basic types: the pressurized-water reactor ... ...fuel is fissioned by neutrons that have been slowed down by a moderator until they are in thermal equilibrium with the moderator. The boiling ... ...

A power reactor in which the heat is dissipated from the core using highly pressurized water (about 160 bar) to achieve a high temperature and avoid boiling within the core. The cooling water transfers its heat to the secondary system in a steam generator.

Nuclear reactor design used in nuclear power stations in many countries, and in nuclear-powered submarines. In the PWR, water under pressure is used in a closed system, as a coolant, passing through the reactor to the generator. Boric acid is added as a moderator. The pressurized water circulates...
