Or put another way, the non-nuclear energy investment required to generate electricity for 40 years is repaid in 5 months. Normalized to 1 GigaWatt electrical capacity, the energy required to construct and decommission the plant, which amounts to 4 Peta-Joules PJwhich is repaid in 1. The energy required to dispose of the waste is also 4 PJ and repaid in 1.
The site of this historic event was known as "NPD" Nuclear Power Demonstrationa small, prototype nuclear power plant located on the Ottawa River Nuclear power plant reaction paper east of Rolphton, Ontario, about km north-west of Ottawa along the Ontario-Quebec border.
The story of this historic achievement of begins shortly before the outbreak of World War II, with the German discovery of nuclear fission. Scientists everywhere immediately realized the potential of this new energy source, and in Canada Dr.
Laurence conducted some of the world's first "critical pile" fission experiments at the National Research Council NRC laboratories in Ottawa. Meanwhile, a handful of French scientists escaped to Britain from Paris with almost all the world's supply of heavy water about kgjust ahead of the German invasion.
They and the heavy water eventually ended up in Montreal. While the remainder of Canada's wartime nuclear effort was devoted to helping the American bomb program, the end of hostilities in found this country with the second largest nuclear research infrastructure in the world after the U.
With the wartime diversion out of the way, scientists again turned to the alluring peaceful potential of nuclear energy. In George Laurence, now at Chalk River Laboratories, began advocating a Canadian power reactor based upon natural uranium fuel and heavy water — both areas of domestic expertise.
As the only member of the wartime British-Canadian-American nuclear alliance not to pursue atomic weaponry after the war, Canada found itself cut off from technological cooperation with the other two, and forced to go it alone.
Lewis of Chalk River Laboratories.
Mackenzie, and federal minister C. Howe, lead to preliminary joint feasibility studies between Ontario Hydro and the newly-created crown corporation Atomic Energy of Canada Ltd. This handful of representatives from electric utilities, engineering companies, and manufacturers, joined with AECL's scientists to forge the fundamental design of a prototype heavy-water, natural-uranium-fuelled power reactor that could compete with coal-fired plants.
Although "made-in-Canada" was the overlying goal of this enterprise, "made-in-Ontario" largely resulted by default. Ontario not only provided the industrial base for much of the manufacturing, but was also the seat of Canada's nuclear engineering and scientific expertise, as well as uranium production mined at Elliot Lake, north of the Lake Superior.
The implementation team was now in place: Ontario Hydro would provide the plant site and all conventional equipment, plus operate the plant and purchase the nuclear-generated steam. The site itself was a spot on the Ottawa River, just downstream from Ontario Hydro's massive Des Joachims hydro-electric power station at Rolphton, Ontario.
These were heady days, where design and development proceeded in parallel, and key late-breaking design decisions became the blueprint for future CANDU designs.
The most significant of these decisions was made inwhen the team resolved to redesign the core of the reactor to better reflect the thinking on future CANDU designs. Instead of having one large pressure vessel, as in American designs then being developed, NPD would assume the horizontal, pressure-tube arrangement characteristic of all CANDU cores to this day.
This would make NPD the first commercial power reactor to have a completely replaceable core, and the first to refuel while operating at full power — both signature CANDU traits. More importantly, it meant that international experience would be largely irrelevant to the Canadian nuclear program: Construction continued, and as hurdles and delays were gradually overcome, an Operations group, assembled under Lorne McConnell of Ontario Hydro, prepared to take over and bring Canada into the Nuclear Power Age.
NPD began supplying its first electricity to the Ontario grid on June 4,and reached full power about 20 MWe — enough for 10, homes on June Today Ontario is one of the largest nuclear-powered jurisdictions in the world.
Over the years it was an invaluable test bed for new fuels, materials, components, and instruments — most never envisaged at the time of NPD's conception. Equally important, NPD was the training centre for generations of Canadian and off-shore operations staff.
This role began shortly after the start of operation, when a training program was set up by George Howey of Ontario Hydro. Howey was to oversee the evolution of the training and simulation centre over the next two decades. In a decision was made to shut down NPD permanently, based upon unsupportable maintenance costs.
In its year career it had met and surpassed every goal set for it, and was a strong symbol of Canadian innovation, boldness, tenacity, and self-reliance. The participation of private manufacturing and engineering firms headed by CGE has evolved into a well-established nuclear industry to which most CANDU construction and design contracts are now channelled.

Unfortunately, even before decommissioning, when the nuclear power plant is operating. Fusion power is a theoretical form of power generation in which energy will be generated by using nuclear fusion reactions to produce heat for electricity generation.
In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, and at the same time, they release energy. This is the same process that powers stars like our regardbouddhiste.coms designed to harness this energy are.
