Nuclear Power Demonstration

Nuclear Power Demonstration (or NPD) was the first Canadian nuclear power reactor, and the prototype for the CANDU reactor design. Built by Canadian General Electric (now GE Canada), in partnership with Atomic Energy of Canada Limited (AECL) and the Hydro Electric Power Commission of Ontario (HEPCO, later Ontario Hydro, now Ontario Power Generation) it consisted of a single 22 MWe pressurized heavy water reactor (PHWR) unit located in Rolphton, Ontario, not far from AECL's Chalk River Laboratories. NPD was owned by AECL and operated by Ontario Hydro. The NPD was the prototype and proving ground for research and development that led to commercial application of the CANDU system for generating electric power from a nuclear plant using natural uranium fuel, heavy water moderator and coolant in a pressure tube configuration with on-power refuelling.
