About The Project

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.
