Pressurized Water Reactor:
It is a type of light water reactor that uses ordinary water as the moderator and coolant.
The PWR plant is the most common type of nuclear power reactor in the world.
The Pressurised Heavy Water Reactors (PHWRs) are fuelled by Natural Uranium while Light Water Reactors (LWRs) are fuelled by Low Enriched Uranium.
A PWR has two water systems:
Reactor (primary) system that retrieves heat generated in the reactor.
Turbine (secondary) system that produces electric power with steam generated by that heat.
