Design
The first CANDU was a demonstration unit, the Nuclear Power Demonstrator (NPD). In 1958, before NPD was complete, AECL formed the Nuclear Power Plant Division at Ontario Hydro’s A.W. Manby Service Centre in Toronto to manage the construction of a full-scale prototype for future CANDU commercial power plants. Ontario Hydro would operate the prototype.
The plant would have a 200 MWe reactor and be built in Ontario. The reactor's stainless steel calandria would mass 54.4 tonne (60 ton) and had have a 6.1 metres (20 ft) diameter. The design was compact to reduce the required amount of heavy water moderator; the reactor required several tons of heavy water, which was very expensive at $26 per pound.
Sites along Lake Huron on the shoreline north of Manitoulin Island and along the shoreline from Tobermory to Goderich were considered. Low-lying Douglas Point, within the latter area, was chosen by the end of June 1959; its solid limestone base made it ideal. The Hydro Electric Power Commission acquired a 9.31 square kilometres (2,301 acres) area at the site for $50 to $70 an acre, the going price of farm land at the time.
Gordon Churchill, the Minister of Trade and Commerce, officially announced the decision to build the plant at Douglas Point on 18 June 1959.

Famous quotes containing the word design:
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
