Canada’s chequered history on nuclear safety
A closer look at Canada’s nuclear plants CBC News Canada: Jan 9, 2012 Reports of two radioactive spills at the nuclear power plant in Point Lepreau, N.B., late in 2011 have raised concerns with the head of Canada’s Nuclear Safety Commission.
Michael Binder, the president of the commission, called the news “unsettling.”…….
Some notable nuclear accidents in Canada
Chalk River, 1952 and 1958
A power surge and partial loss of coolant led to significant damage to the NRX reactor core in 1952. It was the world’s first major nuclear reactor disaster, and it resulted in 4.5 tonnes of radioactive water collecting in the cellar of the building. In 1958, a fuel rupture in the reactor led to a fire and complete contamination of the NRU building. The military was called in both times to aid in the cleanup.
Pickering, 1974 and 1983
The most serious nuclear accidents in Canada happened at the Pickering facility east of Toronto, in 1974 and in 1983. In each case, pressure tubes — which hold fuel rods — ruptured. Some coolant escaped, but was recovered before it left the plant, and there was no release of radioactive material from the containment building.
Darlington, 2009
In 2009, more than 200,000 litres of tritium, the radioactive isotope of hydrogen, spilled into Lake Ontario after workers accidentally filled the wrong tank with a mixture of tritium and water. The level of the isotope in the lake was not enough to pose harm to residents. http://www.cbc.ca/news/canada/story/2012/01/09/f-canada-nuclear-reactors.html
