Bruce nuclear power plant, part owned by TransCanada PipelinesCongratulations to environmental allies who have successfully pressured the Obama administration to postpone -- and hopefully ultimately cancel -- TransCanada Pipelines' proposed Keystone XL Pipeline for Canadian tar sands crude oil. But tar sands crude oil isn't the only "dirty, dangerous, and expensive" energy source TransCanada dabbles with. According to its website, it also owns 48.8% of the 3,000 Megawatt-electric (MW-e) Bruce A nuclear power plant, and 31.6% of the 3,200 MW-e Bruce B nuclear power plant. Bruce -- a 9 reactor and radioactive waste complex located in Ontario on the shore of Lake Huron just 50 miles from Michigan -- is the largest nuclear power plant in the Western Hemisphere, and the second biggest in the world. TransCanada entered the nuclear power business despite warnings by NIRS in late 2002 about serious financial and environmental risks. (A primary bone of contention over the Keystone XL pipeline is its proposed route over the irreplacable Ogallala Aquifer; the Waste Control Specialists radioactive waste dump in Texas also threatens the Ogallala.)
