The U.S. imports uranium from Russia. What if sanctions end that?

If sanctions are imposed on Rosatom, Russia’s civilian nuclear firm, it could cut off exports of uranium to the U.S. and European nuclear industry. What would be the impact?

Russia’s state-owned nuclear power conglomerate, Rosatom, is suspected of supplying the Russian arms industry with components, technology and raw materials for missile fuel, The Washington Post reported Friday. The military goods were sent to more than half a dozen major weapons makers, aiding Moscow’s continuing assault on Ukraine.

That has elevated prospects that the United States, and possibly the European Union, might place sanctions on Rosatom, which exports uranium for use in nuclear reactors.

U.S. reliance on Russian nuclear fuel is substantial, but American companies have some options if Rosatom is hit with sanctions.

How did the United States and Russia get entwined in the civilian nuclear business?

After the end of the Cold War, U.S. and Russian leaders agreed that Russia would dismantle some of its nuclear weapons and send them to the United States to be repurposed and used in civilian nuclear reactors — the megaton to megawatt program. That ended in 2013. Over the course of the 20-year program as much as 10 percent of U.S. electricity came from fuel fabricated from Russian warheads.

Just how much uranium does the United States purchase from Russia now?

In 2021, the United States purchased 14 percent of its uranium from Russia.

However, Russia has the world’s largest uranium enrichment capabilities, accounting for almost half the global capacity. So most of its exports originate in other countries. Most of the uranium Russia exports is bought from Kazakhstan — a country that is landlocked and ships its uranium to Europe and the United States through Russia.

Will prices go up the way oil and natural gas prices did?

Henry Sokolski, executive director of the Nonproliferation Policy Education Center, said that “at worst, some long-term Russian supply contracts could not be executed, and that would perhaps raise the price of electricity 1 or 2 percent.”

But, he added, “given that we’re spending $100 billion plus to help Ukraine out, it would be a rounding error.”

Can that source of supply be replaced quickly?

This isn’t a case of an unplanned Ukrainian winter. American utilities made long-range plans even before war broke out. Paul Adams, a spokesman for Constellation, the largest U.S. nuclear utility, with 21 reactors, said it has made purchases “years in advance” to secure enough fuel to last “multiple years — regardless of potential sanctions.” To do so requires that uranium is mined, enriched and installed in fuel rods.

Russia’s state nuclear company aids war effort, leading to calls for sanctions

But the scramble for more natural uranium supplies is already underway and prices, which had dipped, have recovered. The United States has looked to Canada where Cameco, the world’s second-largest uranium supplier, has agreed to reopen two of its major mines. In addition, another Canadian mining company, Global Atomic, said it will develop a uranium mine in Niger that might start up in 2025.

Are there other options for U.S. companies?

More difficult than mining for uranium is Russia’s domination of the process of enriching it, said Frank N. von Hippel, co-founder of Princeton University’s Program on Science and Global Security and the International Panel on Fissile Materials. He said that one way to deal with that would be to “overfeed” enrichment plants so that more natural uranium goes there, and more of the Uranium 235 goes into the depleted uranium waste product of these plants.

Von Hippel thinks some uranium from Kazakhstan could be exported through China. Jessica Reyes Sondgeroth, deputy editor of Nuclear Intelligence Weekly, said that was “perfectly legal,” but difficult given trade tensions. And Zhang Hui, of Harvard University’s Kennedy School of Government, said in an email that China’s enrichment capacity “is just able to meet (or match) its own domestic reactors’ needs.”

How much would sanctions hurt the Russia economy?

U.S. and European customers of Russian uranium and enrichment comes to about $1 billion, according to von Hippel. That is tiny compared with the impact of sanctions on Russian oil and natural gas, but von Hippel said it would be a setback for Rosatom, which has estimated its foreign earnings to be around $8 billion.

Can Rosatom evade U.S. sanctions through a middleman?

Earlier this year, Europe and the United States were able to target Russian oil and gas shipments even though there were traders and shipping companies in the middle of those deals. Those middlemen were vulnerable too.

In general, Russian nuclear fuel material is bought through Tenex, a Rosatom subsidiary, and Centrus Energy, the U.S. entity, according to one U.S. company.

Will the United States impose sanctions on its own or with its European allies?

There are a couple of obstacles for Europeans. A handful of reactors with Russian designs are situated in the European Union. They will need Russian refueling.

U.S. companies are more likely to support the administration’s position. “Constellation stands with Ukraine against this unprovoked invasion, and we support U.S. and international efforts to bring the war to an end,” Adams said in an email.

Understanding our climate: Global warming is a real phenomenon, and weather disasters are undeniably linked to it. As temperatures rise, heat waves are more often sweeping the globe — and parts of the world are becoming too hot to survive.

What can be done? The Post is tracking a variety of climate solutions, as well as the Biden administration’s actions on environmental issues. It can feel overwhelming facing the impacts of climate change, but there are ways to cope with climate anxiety.

Inventive solutions: Some people have built off-the-grid homes from trash to stand up to a changing climate. As seas rise, others are exploring how to harness marine energy.
