Bad News for Nuclear: A Landmark Reactor Just Got Delayed
Ontario Power Generation is reassessing the schedule and budget for the Darlington small modular reactor project, North America's first grid-scale SMR deployment. Multiple reports confirm the BWRX-300 unit faces delays and cost overruns, prompting a formal review. The project, intended to be the G7's first operational SMR, has awarded supply contracts to Greater Toronto manufacturers including an Oakville steel supplier. Ontario's government recently highlighted these contracts as a milestone, even as the timeline shifts.

Ontario Power Generation to Revise Darlington SMR Timeline and Costs Amid Delays
Ontario Power Generation is reassessing the schedule and budget for the Darlington small modular reactor project, North America's first grid-scale SMR deployment. Multiple reports confirm the BWRX-300 unit faces delays and cost overruns, prompting a formal review. The project, intended to be the G7's first operational SMR, has awarded supply contracts to Greater Toronto manufacturers including an Oakville steel supplier. Ontario's government recently highlighted these contracts as a milestone, even as the timeline shifts.
Why it matters
The Darlington SMR is a critical test case for nuclear's role in decarbonization, using GE Hitachi's BWRX-300 design. Success would validate SMR economics and licensing pathways for Western fleets. Delays and cost growth at this first-of-a-kind project risk undermining investor confidence in the broader SMR pipeline, which several countries are counting on for 2030s clean-energy targets.
What is confirmed
- Ontario Power Generation is set to revise the timeline and cost for the first Darlington SMR unit.
- The Darlington small modular reactor project faces delays and cost overruns.
- Ontario awarded contracts to Greater Toronto Area manufacturers to build components for the G7's first small modular reactor.
- An Oakville company secured a contract to supply steel for the Darlington nuclear reactor.
Still unconfirmed
- The Barron's headline 'Bad News for Nuclear: A Landmark Reactor Just Got Delayed' refers specifically to the Darlington SMR project.
What to watch next
- OPG's revised cost and schedule announcement
- Canadian Nuclear Safety Commission licensing decisions for construction
- GE Hitachi BWRX-300 deployment progress at other sites (e.g., TVA Clinch River)
