Ontario (Canada) Power Generation (OPG) will be soon building GE/Hitachi's latest GEN-IV Small Modular Nuclear Power Plant (BWRX-300) and hopefully have it completed by 2028. While Canada's need for nuclear power is minimal due to it's abundant hydro power, there's expectation that Canada might utilize its experience with this technology to market it around the world, per this excerpt...
"This first-of-a-kind reactor represents the future of nuclear power, not only in Canada, but across the world," Heather Chalmers, president and CEO of GE Canada, said during the livestreamed announcement. "By making this decision, OPG and Ontario are demonstrating a clear example of how Canada can lead in the global energy transition … Ontario and OPG are positioned to be the first mover in small modular reactor technology globally," she said."
For GE/Hitachi and the U.S., there is a marked benefit to having an already approved site available for construction...much faster 'time to market' for this technology, than trying to get it started here.
btw, preliminary analysis projects the cost to consumers to be on the order of what a gas-fired plant would charge.
