RENEW CANADA – TOP100 2026
OPG
The Darlington New Nuclear Project will see the construction of four small
modular reactors (SMRs), that will produce 1,200 megawatts (MW) of electricity.
The Darlington SMR will be a GE Hitachi BWRX-300 reactor. All site grading
for future units is now complete, along with the first phase of geotechnical
investigations. Excavation work on the first unit’s reactor building shaft has
reached 80 per cent completion. Fabrication of basemat modules—which will
serve as the foundation of the first unit’s reactor building—continues to progress
with completed modules being assembled in the pre-assembly building. Once the
reactor building shaft is wholly excavated, the fully assembled basemat will be
lifted by heavy crane and placed at the bottom of the shaft in early 2026.
