Canada successfully refurbished a working nuclear reactor by cutting an opening in the containment structure to replace eight steam generators and return it to operation ahead of schedule. This is a significant engineering achievement that extends the reactor's operational life by roughly three decades, avoiding the construction costs and timeline of a new facility. The project is part of broader North American nuclear expansion plans — both the US and Canada are pursuing major reactor buildout strategies to meet growing electricity demand, particularly from AI infrastructure and industrial electrification.
