Atomic Energy of Canada Ltd’s (AECL) aging nuclear reactor at Chalk River, Ontario, Canada will not be back up and running until the spring of 2010. AECL says a detailed analysis has found nine sites at the reactor needing repair. AECL says the repairs are not a public safety issue, adding there is no threat to workers on site or the environment. Meantime, the ministers of health and natural resources issued a joint statement saying they are disappointed the Chalk River facility will not be back online until the first quarter of 2010. Ottawa is working with the provinces, territories, the medical community and international partners to address Canadian medical isotope needs during this outage. Doctors have scrambled to make do with an erratic supply of isotopes since AECL powered down Chalk River in May after finding a leak of radioactive water.
