Heavy Water Reactor (HWR)

A Heavy Water Reactor (HWR) is a type of nuclear power reactor that uses heavy water (deuterium oxide, D2O) instead of regular water (H2O) as a coolant and neutron moderator. The heavy water slows down neutrons more effectively, allowing the reactor to use natural uranium as fuel, which is less processed than fuel used in other reactors. This makes HWRs generally more efficient and versatile. They can generate electricity or produce isotopes for medical and industrial use. HWRs are known for their safety and lower nuclear waste generation compared to other reactor types.
