| − | Canadian deuterium uranium reactor (CANDU) uses heavy water or deuterium oxide (D<sub>2</sub>O), rather than light water (H<sub>2</sub>O), as the coolant and moderator. | + | '''Canadian deuterium uranium reactor''' (CANDU) is a pressurized heavy water nuclear reactor using deuterium oxide (D<sub>2</sub>O), rather than light water (H<sub>2</sub>O), as the coolant and moderator. In a deuterium-moderated-reactor, fuel made from natural [[uranium]] (0.71 U-235) can sustain a [[chain reaction]]. The CANDU reactor core also allows of on-power refueling, which makes for greater efficiency. |
| | + | CANDU was developed by the Atomic Energy of Canada (AECL) along with the electrical utility of Ontario, and private industry including [[General_Electric|GE]] Canada. All of the current nuclear reactors in Canada are of the CANDU Design, including 20 in [[Ontario]], 1 in [[New Brunswick]] and one in [[Quebec]]. 12 CANDU reactors have also sold and are in use around the world. AECL is still trying to sell more CANDU reactors both in Canada and around the world. |
