Chalk River shut down, again

A power outage and water leak could lead to isotope shortage

The troubled nuclear reactor at Chalk River, Ont., has been shut down, prompting new concerns of a medical isotope shortage. The reactor was first struck with a power outage last week. The next day a heavy water leak was detected. Atomic Energy of Canada Ltd. estimates the facility will be out of use for at least a month. This is but the latest trouble for a facility that was at the centre of a furious political dispute in November 2007.
