Welder training and weld equipment testing and verification in the Chalk River, Ontario-based National Research Universal (NRU) reactor mock-up has been completed, according to the Atomic Energy of Canada Limited (AECL).
Preparations are underway to disassemble the weld tooling for relocation to the top of the NRU reactor for installation, according to the NRU status report. Once the equipment is in position, AECL said that a test weld will be conducted and assessed prior to initiating the actual repairs.
Analysis and testing of the “scoop” samples taken from the wall of the reactor vessel in October has been completed. NRU will return to service during the first calendar quarter of 2010, according to AECL.
