Atomic Energy of Canada Limited (AECL) has reported that work continues on qualifying the welders to perform the complex weld techniques on the final repair site of Chalk River, Ontario-based National Research Universal (NRU) reactor.
AECL said that 71 percent of the weld repairs and associated non-destructive examinations have been completed and the repair team will next apply plates and both horizontal and vertical welds to the repair site.
AECL’s return-to-service project director Dave Cox said that the NRU repair team is performing training and reliability testing on the NRU reactor mock-ups in preparation of performing the final repair to the vessel.
It is estimated that NRU will resume isotope production by the end of July. Further guidance on the return-to-service date will be provided when more information becomes available, said AECL.
