The Strategic Vulnerability of Western Supply Chains

The global market for High-Assay Low-Enriched Uranium (HALEU) is currently characterized by a profound geopolitical imbalance. Russia’s grip on the HALEU supply chain for advanced reactors remains exceptionally strong. In fact, Russia’s state-owned nuclear fuel subsidiary, TENEX, is effectively the only company currently capable of supplying HALEU fuel on a commercial scale, leaving Western advanced reactor developers in a highly vulnerable position.

Rosatom's Overwhelming Market Share

This HALEU monopoly is underpinned by Russia's broader dominance in the global uranium enrichment sector. Last year, Rosatom's annual uranium enrichment capacity stood at a massive 29.13 million Separative Work Units (SWU). This accounts for approximately 43% of global capacity, significantly exceeding Western competitors like Urenco (17.3 million SWU) and Orano (7.5 million SWU). This overwhelming capacity gives Moscow substantial leverage over the global nuclear fuel market.

"Russia’s TENEX is effectively the only company currently capable of supplying HALEU fuel on a commercial scale, highlighting critical supply chain vulnerabilities."

The geopolitical risks associated with this reliance have prompted urgent policy reviews. In 2024, Russian President Vladimir Putin formally called for a review of resource controls, suggesting potential restrictions on critical commodities like uranium, titanium, and nickel in response to Western sanctions. Such a move would severely disrupt the fuel supply for advanced reactors in the U.S. and Europe.

In response, Western policymakers are actively working to decouple from Russian nuclear services. The U.S. ban on Russian uranium imports took full effect in August 2024, albeit with temporary waivers extending through 2027. Consequently, U.S. uranium feedstock sent to Russian enrichment facilities fell by approximately 38% last year. Meanwhile, the Euratom Supply Agency reported that Russia still supplied nearly 24.4% of conversion services and 22.6% of enrichment services to the EU, underscoring the long road ahead for Western energy independence.
