**Deck**: Despite sanctions and sharp rhetoric, the U.S. still relies heavily on Russia’s Rosatom to enrich uranium for its nuclear power plants after letting domestic capacity wither. A looming ban on Russian uranium imports could collide with this reality, forcing Washington to balance energy security, climate goals and sanctions policy.

For all the political talk about cutting ties with Moscow, one of the quietest U.S. energy dependencies still runs straight through Russia’s nuclear industry.

The United States continues to rely heavily on Russia for uranium enrichment, a crucial step in turning mined uranium into fuel for nuclear reactors. After the post‑Cold War program that reprocessed Soviet weapons‑grade uranium into reactor fuel wound down, American enrichment capacity shrank dramatically. Russia’s state‑owned Rosatom, by contrast, maintained and expanded its facilities, keeping the largest share of the global enrichment market.

That structural imbalance means U.S. utilities buying fuel for civilian nuclear plants often end up sourcing enriched uranium from Rosatom or its subsidiaries, even as Washington layers sanctions on other parts of Russia’s economy. Nuclear fuel has been carved out of many sanctions regimes precisely because there hasn’t been an easy short‑term replacement.

The reliance isn’t just a theoretical vulnerability buried in trade statistics. Nuclear power still supplies a significant portion of U.S. electricity, and it’s central to many states’ plans for decarbonizing their grids. If Russian enriched uranium were suddenly unavailable, reactor operators would scramble to find alternative suppliers, potentially driving up costs, compressing safety and regulatory timelines, or in the worst case forcing some plants to consider reduced output or early closure.

A formal ban on Russian uranium imports has been under discussion, reflecting bipartisan frustration with continued nuclear trade in the middle of a broader confrontation with the Kremlin. But that ban “to…” — as some reporting tersely puts it — runs head‑first into the reality that replacing Rosatom overnight isn’t possible. Building new enrichment capacity in the U.S. or friendly countries takes years of investment, regulatory clearances and specialized technology.

For American consumers, the stakes are indirect but real. Nuclear power helps anchor baseline electricity prices and provides low‑carbon capacity that doesn’t depend on weather conditions, unlike wind or solar. If fuel supply becomes more expensive or uncertain, utilities might pass some of those costs through to ratepayers or lean more heavily on gas‑fired generation, with implications for both bills and emissions.

Strategically, the dependency gives Moscow a lever, even if it hasn’t pulled it yet. Knowing that U.S. utilities and their European counterparts still need enriched uranium from Russian facilities softens the blow of other sanctions and offers Rosatom lucrative, hard‑currency contracts. It also complicates Western efforts to present a clean break with Russian energy, especially as Europe moves away from Russian gas but quietly continues nuclear imports.

For non‑aligned countries weighing their own nuclear plans, the picture is instructive: turn to Rosatom, and you get bundled construction, fuel and service contracts on favorable financing — but also long‑term exposure to geopolitical risk. Rely more on Western technology, and you face higher up‑front costs and a still‑fragmented enrichment market.

The uncomfortable insight is that the U.S. can sanction Russian pipelines and oil tankers, but as long as its reactors burn fuel enriched in Russia, energy independence remains a slogan, not a fact.

What to watch now are concrete moves in Washington and allied capitals: legislation that would phase in a Russian uranium ban and allocate funding for domestic or allied enrichment projects; new investments by firms in the U.S., Europe and Asia to scale up capacity; and any shift in Rosatom’s export strategy that suggests Moscow is preparing for a partial loss of Western markets. Utility procurement contracts and the timelines on which they start to diversify away from Russian supply will offer an early, technical view of how fast this hidden dependency can actually be unwound.
