CANDU, an acronym for "CANada Deuterium Uranium," refers to a specific type of pressurized heavy water nuclear reactor design that was developed in Canada. It is a trademark registered by Atomic Energy of Canada Limited (AECL), a Canadian Crown corporation responsible for developing nuclear technology.
The CANDU reactor design is known for its unique features, particularly the use of heavy water as both a moderator and coolant. This heavy water, called deuterium oxide, allows the reactor to operate using natural uranium as fuel instead of enriched uranium. The use of natural uranium makes CANDU reactors highly efficient, reducing the need for costly enrichment processes.
Another important characteristic of CANDU reactors is their ability to refuel while still in operation, commonly referred to as online refueling. This feature sets them apart from many other nuclear reactor designs, as it allows for more consistent and continuous electricity generation without the need for extended shutdown periods.
CANDU reactors have gained widespread recognition for their enhanced safety features, including passive safety systems and inherent stability during various reactor conditions. These safety measures make CANDU reactors highly reliable and reduce the risk of potential accidents.
Due to its efficiency, inherent safety features, and ability for online refueling, the CANDU reactor design has been adopted by several countries around the world, making it a significant player in global nuclear power generation.
