Canada to build first of four small modular nuclear reactors

SMRs are expected to be produced in factories and assembled on site, a strategy that supporters say will eventually be cheaper and faster than building large, conventional reactors, such as Darlington's full-size reactor mock-up seen in this photo.SMRs are expected to be produced in factories and assembled on site, a strategy that supporters say will eventually be cheaper and faster than building large, conventional reactors, such as Darlington's full-size reactor mock-up seen in this photo.

Ontario Power Generation Inc. won approval to build the first of a planned four reactors, each costing billions of dollars, according to a statement Thursday. The announcement follows last month’s decision by Canada’s nuclear regulator to issue a construction license for the so-called small modular reactor (SMR) at the company’s Darlington New Nuclear Project site.

Interest in nuclear power is rising around the world, as technology companies and governments eye fission as a source of stable, clean power that can help meet rising demand for electricity. SMRs are expected to be produced in factories and assembled on site, a strategy that supporters say will eventually be cheaper and faster than building large, conventional reactors.

Article content

To date, only a handful of SMRs have been completed and only in Russia and China. The Darlington project is expected to be the first small reactor to be deployed in the developed Group of Seven countries.

Ontario Power signed an agreement in 2023 with GE Hitachi Nuclear Energy to deploy its BWRX-300 SMR at the Darlington site. The unit has roughly 300 megawatts of capacity, compared to traditional nuclear reactors that have about three times more capacity.
