Ont. nuclear reactor running despite 'significant' leak

OTTAWA - The nuclear reactor that is the source of more than half of the world's medical isotopes was back to full production Monday, even as engineers and technicians at the Chalk River, Ont., facility were making plans to fix a "significant" leak in one of the key pieces of machinery that is part of the reactor's core.
"The reactor is operating normally and safely," said Bill Pilkington, chief nuclear officer for Atomic Energy of Canada Ltd., the Crown corporation that operates the National Research Universal reactor at Chalk River.
But the discovery of the leak comes as nuclear medicine specialists, mostly in Eastern Canada, are scrambling this week to adjust patient treatment schedules in the wake of an interruption of their supply of medical isotopes, which developed after a routine five-day maintenance shutdown of the NRU was extended to seven days. The leak was not a factor in the extension of that shutdown.
Nuclear medicine experts said they expect only to be able to perform emergency procedures until their supply of medical isotopes can be topped up, likely at the end of the week.
