Canada's New Nuclear Reactors to Rely on Foreign Fuel Enrichment, Shifting from Past Self-Sufficiency

Canada's planned nuclear expansion, featuring new Small Modular Reactors (SMRs) like the BWRX-300 being built in Ontario, marks a notable shift in its energy strategy. Unlike the established Candu reactor system, which utilized domestically sourced natural uranium and fostered a largely self-sufficient fuel supply chain for decades, the new SMRs will depend on foreign entities for uranium enrichment and fuel fabrication. Ontario Power Generation (OPG) has contracted suppliers in the United States, France, and Britain for these critical processes. This reliance on international partners for enrichment and fabrication, while intended to create a robust supply chain, raises concerns among experts regarding Canada's energy sovereignty and potential geopolitical risks. The original rationale for the Candu program was precisely to avoid dependence on foreign enrichment, a cornerstone of Canadian nuclear policy for over fifty years. Provincial officials cite the lack of a readily available Canadian grid-scale SMR technology as the reason for seeking international solutions. While multiple international suppliers are intended to mitigate risk, critics argue that foreign control over essential fuel processing steps still exposes Canada to vulnerabilities. The federal government acknowledges the fuel requirements are modest, but the long-term implications for waste management and geopolitical stability are subjects of ongoing discussion.
