Cameco Corporation
CCJ · ARCX · Uranium · Canada
Cameco Corporation is a leading global provider of uranium fuel essential for generating safe, reliable, carbon-free nuclear power. The company operates through three key segments: Uranium, Fuel Services, and Westinghouse. The Uranium segment focuses on exploration, mining, milling, purchase, and sale of uranium concentrate from high-grade operations, including tier-one mines in Canada's Athabasca Basin such as Cigar Lake and McArthur River/Key Lake, as well as in situ recovery (ISR) projects in the United States, Wyoming, Nebraska, and a joint venture in Kazakhstan. Fuel Services handles refining, conversion, and fabrication of uranium concentrate, along with related services. The Westinghouse segment positions Cameco as an original equipment manufacturer for nuclear reactor technology. With interests in the world's largest high-grade uranium reserves and low-cost operations, diversified by geography and deposit type, Cameco supplies utilities across the Americas, Europe, and Asia. Founded in 1988 and headquartered in Saskatoon, Saskatchewan, Canada, it maintains high standards in safety, health, environmental performance, and innovative mining techniques like ISR and jet boring.

Supply Chain
Nuclear Energy Supply Chain
The nuclear energy supply chain is shaped by three structural constraints that most industries never encounter: regulatory and licensing timelines that stretch beyond a decade before a reactor generates a single watt, a fuel cycle where each step — mining, conversion, enrichment, fabrication — is restricted by both physics and international treaty, and a decommissioning obligation embedded from the moment a plant is approved, binding operators to costs that extend decades beyond the last kilowatt-hour sold.
Uranium Supply Chain
The uranium supply chain is shaped by three structural constraints that interact to create one of the most politically and technically constricted commodity systems on earth: enrichment capacity is concentrated in a handful of state-affiliated facilities worldwide, and the centrifuge technology is dual-use with weapons, making it the most geopolitically constrained chokepoint in any commodity chain; the mine-to-reactor pathway requires uranium to pass through five discrete transformation stages — mining, milling, conversion, enrichment, and fuel fabrication — each with qualification barriers and few participants; and for decades, secondary supply from dismantled nuclear warheads masked chronic underinvestment in primary mining, creating a structural illusion of adequacy that began to unravel when the Megatons to Megawatts program ended in 2013.
