GE Vernova Hitachi: The First SMR in the West
Construction is expected to begin soon on the first small modular reactor (SMR) in the Western world.
GE Vernova Hitachi Nuclear Energy has announced approval from the Province of Ontario and Ontario Power Generation to commence development of this SMR in Ontario, Canada.
The BWRX-300 is built on a standard design, offering a tangible solution to energy security and decarbonisation challenges.
“This historic achievement in small modular reactor technology is more than a milestone, it’s a clear signal that we are ready to meet the moment,” says Scott Strazik, CEO at GE Vernova.
“As we build toward a more holistic energy future, this achievement with the BWRX-300 shows how innovation in nuclear can deliver reliable, baseload, zero-carbon power generation.
“As we confront the challenges of increased demand, energy security and carbon intensity, this milestone reaffirms our commitment to innovation and a more sustainable energy future.”
What is an SMR?
SMRs are a pivotal shift in nuclear energy technology.
They are defined as reactors with a maximum output of 300MW, producing around 7.2 million kWh per day.
Traditional power plants can exceed 1000MW and generate 24 million kWh daily.
The compactness of SMRs allows them to be deployed in energy grid regions that are isolated and would be unsuitable for larger reactors.
SMRs are usually prefabricated in factories and assembled on-site, significantly reducing construction time.
Their modular design supports incremental expansion, allowing additional units as energy demand surges.
Refuelling for SMRs occurs every three to seven years, opposed to one to two years for traditional reactors.
However, there are concerns that SMRs could produce more waste than traditional reactors.
About the BWRX-300
Each BWRX-300 can provide around 300MW of electricity.
This is enough to power 300,000 homes but without the complexity and cost associated with traditional nuclear reactors.
It utilises up to 90% less land, presenting a flexible solution for delivering carbon-neutral electricity.
The reactor operates on the tried-and-tested GNF2 fuel, benefiting from an established and supported supply chain.
“The experience and efficiencies gained from deploying the first BWRX-300 at Darlington alongside OPG and our other partners will pave the way for subsequent SMR projects by establishing a proven model for construction and operation,” says Craig Ranson, President and CEO of GE Vernova Hitachi Nuclear Energy.
“The standardised design and modular approach of the BWRX-300 enable economies of scale, making it easier and more cost-effective to replicate the construction process at other sites.”
Will more SMRs follow?
Globally, more than 80 SMR designs are under development according to the International Atomic Energy Agency.
It recognises four SMRs in advanced construction phases across Argentina, China and Russia.
Technology companies, such as Amazon and Google, are showing interest in this tech to power data centres as AI and data growth is dramatically increasing their energy demand.
To reach net zero by 2050, the International Energy Agency says nuclear power worldwide needs to double between 2020 and 2050.
“This is important because nuclear power is the world’s second largest source of low carbon electricity after hydropower,” Craig Jones, Vice President, UK Energy Transition at GE Vernova, says.
“Countries such as the US, Poland and Sweden are looking to follow Canada’s lead.”
