The AP1000 reactor has a globally proven track record, with a growing fleet delivering safe, reliable power and record-setting performance
As the only Generation III+ reactor with passive safety systems in commercial service, it is operating in multiple countries and selected for new programs across Europe, Asia, and North America.

Performance data source: IAEA PRIS databaseThe reactor is designed to achieve and maintain safe shutdown conditions without operator action, and without the need for AC power or pumps.
Equally important to the technological advances and performance of the AP1000 are the approaches taken to new builds. Developed over the course of the initial units' entries into the AP1000 fleet, new plant projects have been standardized, sequenced and, incrementally simplified as experience grows; all to continually optimize construction timelines and reduce costs.
Fully digital and AI-enabled construction process automates construction documentation, licensing, planning and more to deliver AP1000 units efficiently and repeatably.

Reviewed by multiple regulators around the world, the AP1000 reactor is the only Generation III+ reactor that has received a design certification and a construction and operating license from the U.S. Nuclear Regulatory Commission.
The AP1000 plant design also has been independently assessed and confirmed to meet the requirements of the European Utilities Requirements document and the Electric Power Research Institute Advanced Light Water Reactor Utility Requirements Document.
Design review by China's National Nuclear Safety Administration (NNSA) is complete.
Design has passed Phase 2 of the CNSC three-stage review process. "Based on the Phase 2 review, CNSC staff conclude that there are no fundamental barriers to licensing the AP1000 design in Canada."
AP1000 construction schedule is simple with known major milestones (Long Lead Item Orders, Early Works Construction, etc.)
Lower construction risk with the AP1000 improves financing outcomes and protects ratepayers
An investment today in the proven, construction-ready AP1000 would be focused on swift, measurable project build progress, with immediate downstream benefits. Assuming a four-unit AP1000 project is initiated in Ontario, immediate incremental manufacturing and supply chain jobs is expected to inject about $5 billion into the Canadian economy.
Construction on the first unit would see about 80% of that investment retained in Ontario, growing to about 90% by the fourth unit.
As other nations continue quickly expanding their nuclear fleet capacity with the world’s only deployment-ready, modern AP1000 reactors, we anticipate growing export opportunities for Canada’s experienced, reliable nuclear supply chain.
