Small modular reactors
Like mobile phones and home computers, many things get smaller and more efficient over time.
Ontario’s nuclear energy potential is no exception, and Ontario Power Generation is helping lead the way in the advancement of small modular reactor (SMR) technology – the future of nuclear power generation.
Learn how these small, carbon-free, modular reactors can help meet Ontario’s changing energy needs while combating climate change.

Small modular reactor facts
SMRs require far less space than traditional reactors
Heat and power are efficiently generated through fission
SMRs are factory constructed and delivered to site
Over 150 SMR technologies proposed, worldwide
The next generation of nuclear
SMRs, like current nuclear reactors, are designed to provide reliable, carbon-free electricity, but with a much-smaller land footprint than current reactors.
Factory constructed and modular, many SMRs are delivered to site and can be used for generating electricity as well as producing heat used for other applications like district heating for commercial or residential needs, hybrid energy systems, water desalination, or heavy industry applications.
From 1 megawatt to 300 megawatts, SMRs are a reliable alternate energy source to diesel in rural communities, and a significant growth opportunity for OPG and Ontario.
SMRs are good for Canada
A 2018 collaborative study found SMRs could be a beneficial addition to Canada’s energy mix and urged the Canadian government to support the advancement of SMRs. The Canadian roadmap study for SMR deployment report found that Canada is uniquely positioned to lead the world in SMR development given its long history in nuclear power.
To bring SMRs to Canada, OPG is collaborating with many leading SMR vendors who are working to deploy ground-breaking SMR technologies. One example, OPG is supporting Global First Power’s proposal to construct and operate Canada’s first proposed SMR at Canadian Nuclear Laboratories’ Chalk River site.
