Crews have found the source of a heavy water leak at the Chalk River reactor in eastern Ontario, but more inspections will be needed before a repair plan can be worked out, Atomic Energy of Canada Ltd. said.
"We now believe that the NRU reactor will be out of service for at least three months."
The Chalk River reactor produces most of the radioactive istopes used in medical procedures in North America. Thousands of medical scans and treatments have been postponed.
Update: Greg Weston in today's Ottawa Sun:
"Canada's only medical isotope reactor will be out of service for the rest of the year and possibly forever, leaving thousands of desperate cancer and heart patients across the country with a shortage of nuclear scans and treatments."
"As one government official puts it, "that reactor has a cancer of its own -- spreading corrosion."
