A Canadian nuclear reactor is set to resume producing medical isotopes after being shut for 15 months of repairs.
The National Research Universal reactor in Chalk River, Ontario, was closed in May 2009 after a leak of heavy water within the reactor. It had been producing about a third of the world supply of medical isotopes.
The disruption to supply caused delays and cancellations of diagnostic tests that use the isotopes, including scans for cardiovascular disease and cancer…
The shortage caused by the Chalk River reactor’s closure was exacerbated by the shut-down for maintenance of another major isotope-producing reactor in Petten, in the Netherlands.
The isotopes produced at the Chalk River plant are used for medical imaging and diagnostic scans for fractures, cancer and heart conditions.
