Located in Rolphton, Ontario, the NPD reactor served as a prototype for future full-scale nuclear power stations and helped demonstrate the safe operation of heavy water moderated natural uranium reactors. It began supplying electricity in Ontario on June 4, 1962, and was used as a training facility for nuclear reactor operators. While in service, it was operated by Ontario Hydro.
Located at the Whiteshell Laboratories in Manitoba, the WR-1 was the largest organically cooled, heavy water moderated nuclear reactor in the world and played an important role in building Canada’s scientific and industrial capacity. Originally built as a test reactor for a proposed CANDU power reactor, it later went on to be used for nuclear fuel research and other programs.
Located in Kincardine, Ontario, the Douglas Point reactor was once the largest steam condenser in Canada and provided valuable operating experience to Ontario Hydro and AECL in advancing reactor development. It provided electricity to Ontario’s power grid and served as a source of steam for a heavy-water extraction plant.
