US seeks to phase out Russian uranium supplies ahead of import ban

US: The United States government is advancing policies to reduce dependence on Russian sources for nuclear fuel enrichment services critical to its domestic reactors. Recent legislative measures passed in September 2026 reinforce existing restrictions on Russian uranium while including targeted exceptions for civilian nuclear cooperation. This directly supports the ongoing phase-out of such supplies to ensure readiness for the full import prohibition. Sanctions: Recent US sanctions legislation targets purchasers of Russian oil and gas with high tariffs but preserves limited exceptions for specific low-enriched uranium imports under existing nuclear cooperation agreements. Energy Policy: The US is pressing domestic and allied suppliers to accelerate uranium enrichment capacity expansion to address potential supply shortfalls from reduced Russian imports.
