The CANDU reactor (short for CANada Deuterium Uranium) is a Canadian-developed, pressurized heavy water reactor used for generating electric power. The acronym refers to its deuterium-oxide (heavy water) moderator and its use of (originally, natural) uranium fuel. CANDU reactors were first developed in the late 1950s and 1960s by a partnership between Atomic Energy of Canada Limited (AECL), the Hydro-Electric Power Commission of Ontario, Canadian General Electric, and other companies. All power reactors built in Canada are of the CANDU type. The reactor is also marketed abroad and there are CANDU-type units operating in India, Pakistan, Argentina, South Korea, Romania and China. In October 2011, the Canadian Federal Government licensed the CANDU design to Candu Energy (a wholly owned subsidiary of SNC-Lavalin), which also acquired the former reactor development and marketing division of AECL at that time.
