America Gets Just 7% Of Its Nuclear Fuel From Home - Canada Supplies The Biggest Share

Only 7% of the uranium delivered to America's nuclear power plants in 2025 came from the United States. The biggest single source was Canada, at 32%, according to the US Energy Information Administration. Most of it comes from two mines in northern Saskatchewan, McArthur River and Cigar Lake, where the ore is about 100 times richer than the world average. We look at Port Hope, Ontario, one of only two plants in North America making uranium hexafluoride, whose licence hearing is in the first week of November 2026, and at how uranium has been taxed lightly or left out of every US tariff on Canada, from the 10% energy tariff in 2025 to the 50% tariffs of August 2026. ⏱ CHAPTERS 0:00 7 percent 1:09 The fuel 2:45 Saskatchewan 4:26 Port Hope 6:19 The trade war 8:15 The alternatives 9:58 The fair side 11:46 The numbers 📚 SOURCES • US Energy Information Administration — 2025 Uranium Marketing Annual Report; Today in Energy (Aug 28, 2026) • Cameco — Q2 2026 MD&A (Form 6-K); annual reports (40-F) • Cameco submission to the Canadian Nuclear Safety Commission, CMD 26-H3-1 (Aug 2026); CNSC hearing notice • US executive order on Canada tariffs (Feb 2025) — law-firm summaries (Torys, Blakes), CH Robinson, GHY • Proclamation on processed critical minerals (Jan 14, 2026) — Thompson Hine, ST&R • Fertilizer Daily / Argus Media (Aug 2026) — energy and critical minerals exempt from 50% tariffs • Prohibiting Russian Uranium Imports Act (2024) — Congress.gov • Cameco / Brookfield / US Government partnership (Oct 27, 2025) — BusinessWire, World Nuclear News 💬 Did you know where America's nuclear fuel comes from?
