The United States operates the world’s largest nuclear power production capacity, yet the sector faces mounting challenges from decades of underinvestment and aging infrastructure. Despite only one new plant being added over the past decade, the Trump administration has prioritized revitalizing nuclear energy as a clean power source. However, this expansion ambition collides with a fundamental constraint: securing adequate fuel supplies.
Global demand for enriched uranium has intensified dramatically as nations race to expand nuclear capacity amid the artificial intelligence-driven energy boom, ongoing geopolitical tensions affecting oil and gas markets, and accelerating decarbonization timelines. This surge in competition for limited enriched uranium reserves has created significant supply chain vulnerabilities and cost pressures affecting both operational reactors and emerging advanced reactor technologies. According to an January report from Stanford Energy, these constraints present a serious threat to both existing and future nuclear development.
The geopolitical dimensions of uranium supply chains pose particular concern. Only five facilities worldwide perform large-scale uranium conversion, with Russia controlling approximately half of global enrichment capacity. This concentration creates critical dependencies; any U.S.-Russia severance could force Western reactors to rely on a single Chinese facility, potentially creating worse outcomes than the original supply constraint. Recent analysis from the National Interest highlights that Western nuclear fleets require approximately 44,000 metric tons of uranium feedstock annually, but Western processing capabilities—including the United States, Canada, and France—total just 34,000 metric tons at full operational capacity.
U.S. leadership has bipartisan support for building domestic uranium capabilities, representing rare consensus between the Trump and Biden administrations. The National Enrichment Facility in Eunice, New Mexico recently announced its planned expansion is ahead of schedule and on budget, with current operations covering roughly one-third of U.S. enriched uranium demand and plans to increase output by more than 50 percent. Nevertheless, 93 percent of American raw uranium currently originates from foreign sources, indicating substantial dependence on external supply chains that could face disruption in an increasingly contentious geopolitical environment.
