Uranium's Real Chokepoint Is Enrichment, Controlled by Russia

Uranium’s supply chain has a genuinely distinctive two-stage structure: mining concentration, covered on this material’s geology and mining pages, and a separate, arguably more consequential enrichment-stage concentration, covered here.

Why enrichment concentration matters more than mining concentration

Because enrichment, covered on this material’s materials science page, requires extremely specialised, capital-intensive centrifuge technology that very few countries have built at scale, Russia’s Rosatom holding the largest single share of world enrichment capacity is a real, exercised geopolitical exposure, Western utilities have had to actively work to reduce dependence on Russian enrichment services following sanctions related to Russia’s invasion of Ukraine, a documented, current supply chain disruption, not a hypothetical.

Why this differs from a simple mining chokepoint

Unlike cobalt’s DRC-to-China mining-to-refining split, covered on cobalt’s supply chain page, uranium’s enrichment concentration sits with a country, Russia, that also happens to be under active sanctions for reasons entirely unrelated to uranium itself, layering a geopolitical risk on top of the technical concentration.
