Flanked by key officials of beleaguered Atomic Energy of Canada Ltd., Clement instead pronounced the day "momentous" because the 50-year-old research reactor beside him was once again producing molybdenum-99, high-grade cobalt-60 and other radioisotopes.
The health minister said the government intends to get to the bottom of what caused the isotope crisis.
Clement also played down speculation that concern over the reliability of the Canadian isotope supply might spur the U.S. to convert an existing research reactor to isotope production.
"It's not a simple thing to create another reactor to produce our isotopes," he said. Owned and operated by AECL, the research reactor was shut down Nov. 18 because of safety violations discovered during routine maintenance.
It restarted Sunday after the government used an emergency law to override the Canadian Nuclear Safety Commission, the independent federal watchdog.
AECL officials said an initial shipment of low-concentration molybdenum-99 was sent Tuesday to isotope wholesaler MDS Nordion of Ottawa, and backlogged orders from hospitals were beginning to be filled.
Dave Torgerson, chief executive officer for AECL's research arm, pointed out that the Crown corporation pioneered both the global medical isotope business and much of the technology used to produce the radioisotopes.
"We take this very, very seriously," he said.
Clement and Torgerson made their remarks here at the nuclear research complex, 180 kilometres north of Ottawa, standing on the main floor of the building that houses the research reactor.
Blue-coated workers hung over railings at the top of the reactor four storeys above. The congratulatory remarks were recorded by three dozen media people who had been allowed into the reactor on one day's notice, access unprecedented since the 9/11 terrorist attacks.
