Mammoet Returns to Bruce Power for Major Upgrade

Mammoet will return to the Bruce Power nuclear power plant in Ontario, Canada, to continue its role in the Major Component Replacement (MCR) project, a key programme aimed at extending the operational life of the facility.

Launched in 2020, the MCR project involves the replacement of major components across six reactor units (Units 3–8) at Bruce A and B. Together, the stations generate over 30% of Ontario’s electricity and produce critical medical isotopes used in cancer treatment.

Following its work on the steam generator exchange at Unit 3 in 2024, Mammoet will now execute a similar scope at Unit 4. Working for the Steam Generator Replacement Team, a joint venture between Aecon and Framatome, the company will provide lifting, transport, and jack-and-slide services.

The six-month operation will include relocating two steam drums and replacing eight steam generators using Mammoet’s 1,600-tonne PTC-35 ring crane. Self-Propelled Modular Transporters (SPMTs) will also be deployed to move decommissioned components into long-term storage.

The PTC crane offers key advantages over conventional crawler cranes, particularly in confined spaces and challenging weather conditions, where stability and efficiency are critical.

Mammoet’s continued involvement highlights its expertise in nuclear projects worldwide, including work at Hinkley Point C, Flamanville nuclear power station, and ITER.
