present a lot of opportunities for Canada to reduce carbon emissions and provide additional benefits to industry, says Fehrenbach. Ranging in size from 60 megawatts to 300 megawatts, these models vary from molten salt reactors to high temperature gas reactors. These innovative designs present opportunities to produce not just electricity but also hydrogen, steam, heat and medical isotopes, depending on the customers’ needs. Other Generation IV SMRs being considered for these applications in Canada include Terrestrial Energy’s IMSR and X-Energy’s Xe-100. “Finally, Stream Three is focused on the provision of advanced reactors to off-grid or remote communities. This micro-SMR class with units below 10 megawatts is ideal for small, standalone sites and also industrial applications,” says Fehrenbach. “Westinghouse Canada’s eVinci micro SMR can be shipped anywhere in the world in three sea cannisters, for example. In Chalk River, Ontario Power Generation and Ultra Safe Nuclear Corporation have a join venture called Global First Power that is also producing a micro-SMR.” All seven of these Canadian companies producing SMRs are taking advantage of the inherent benefits of SMRs over large nuclear—Smallness and Modularity. “Traditional, large nuclear plants require a very large upfront expenditure that secures 30+ years of clean, stable electricity,” says Fehrenbach. “These are suitable for large, baseload applications to supply a very large amount of reliable electricity. Now, with the introduction of SMRs, the provinces and industry have a smaller, more nimble and lesscapital intensive option to ‘round out the corners’ of Moltex Canada’s SSR-W site layout 7
