The Canadian nuclear reactor system, moderated by heavy water (deuterium) and fuelled by natural uranium. The name is derived from CANada, Deuterium and Uranium.
A Canadian designed pressurized heavy water reactor which uses unenriched Uranium as fuel.
Canadian Deuterium Uranium water-cooled reactor type. The fuel consists of un-enriched ceramic uranium oxide pellets within zirconium alloy tubes.
CANDU is the registered trade name for the Canada Deuterium Uranium reactor designed by Atomic Energy of Canada Limited (AECL).
CANDU stands for CANada Deuterium Uranium. The CANDU reactor is a pressurized-heavy water,(PHWR) natural uranium (i.e. unenriched) power reactor; hence, it needs a more efficient moderator than most other power reactor designs - in this case heavy water (D2O, deuterium oxide). This means that they can be operated without expensive fuel enrichment facilities. Most less-developed countries find this attractive because they cannot afford the enrichment facilities, and cannot be assured of access to enriched uranium.
