Cameco Sees As Many As 20 AP1000 Nuclear Reactors On The Horizon
Cameco leadership recently made announcements during their 2026Q1 earnings call regarding an expectation that as many as 20 AP1000 reactors will be announced for constructi
What the Documents Show
Grant Isaac, Cameco's Chief Operating Officer and President, indicated the project "continues to move along," though few substantive updates have surfaced since the agreement's announcement last fall. According to Isaac, current DOC efforts focus on securing "long lead items that are required in order to stand up a fleet of large reactors"—essentially, the foundational components and infrastructure necessary before any construction can begin in earnest. What mainstream coverage of nuclear expansion overlooks is the severity of America's manufacturing capacity crisis in this sector. The domestic and global supply chain outside of China and Russia has atrophied over decades, oriented toward reactor maintenance and decommissioning rather than new construction. Curtiss-Wright, the sole producer of reactor cooling pumps for Westinghouse AP1000 plants, publicly acknowledged capacity constraints that expose an uncomfortable reality: the company can manufacture enough pumps for merely three to four reactors per year.
Follow the Money
This single chokepoint means deploying 20 reactors would require roughly five to seven years of sustained production at maximum capacity—that's before accounting for other component bottlenecks across the supply chain. Isaac's comments on operational models reveal ongoing uncertainty about how these reactors will actually be built and owned. Potential frameworks range from
What Else We Know
For ordinary Americans, these supply chain realities mean promises of nuclear expansion should be viewed with skepticism. Even if political will and federal funding materialize as expected, the physical capacity to manufacture reactor components doesn't exist at the scale required. Unless the government aggressively invests in expanding manufacturing capacity—an expensive, multiyear proposition that hasn't been publicly announced—the gap between Cameco's optimistic projections and actual construction timelines could stretch into the next decade.
