Pressurized heavy-water reactor - Wikipedia

A pressurized heavy-water reactor (PHWR) is a nuclear reactor, commonly using natural uranium as its fuel, that uses heavy water (deuterium oxide D2O) as its coolant and neutron moderator. The heavy water coolant is kept under pressure, allowing it to be heated to higher temperatures without boiling...

Designers choose to use heavy-water in order to minimize the need for enriched uranium. If you use regular water as moderator and/or coolant, the water absorbs a significant amount of the neutrons needed to keep the reaction going. That means you need a big reactor, one with a lot of regular...
