Inscription. On June 4, 1962 the Nuclear Power Demonstration (NPD) Reactor 3 km east of Rolphton supplied the Ontario power grid with the first nuclear-generated electricity in Canada. A joint project of Atomic Energy of Canada Limited, Ontario Hydro and Canadian General Electric, 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. As a science and engineering research centre, NPD produced internationally significant knowledge and techniques. It was also a training centre for nuclear plant operators. NPD closed in 1987 after exceeding its operational goals.
