The US nuclear power industry is lobbying the White House to allow uranium imports from Russia to continue despite the escalating conflict in Ukraine, with cheap supplies of the fuel seen as key to keeping American electricity prices low, according to two sources familiar with the matter.
The United States relies on Russia and its allies Kazakhstan and Uzbekistan for roughly half of the uranium powering its nuclear plants - about 22.8 million pounds (10.3 million kg) in 2020 - which in turn produce about 20% of US electricity, according to the US Energy Information Administration and the World Nuclear Association.
Washington and its allies have imposed a series of sanctions on Moscow in the past week as Russian forces pushed deeper into neighbouring Ukraine, though the sanctions exempt uranium sales and related financial transactions.
The National Energy Institute (NEI), a trade group of US nuclear power generation companies including Duke Energy Corp (DUK.N) and Exelon Corp (EXC.O), is lobbying the White House to keep the exemption on uranium imports from Russia, the sources said.
The NEI lobbying aims to ensure that uranium is not caught up in any future energy-related sanctions, especially as calls intensify to sanction Russian crude oil sales, the sources said.
"The (US nuclear power) industry is just addicted to cheap Russian uranium," said one of the sources, who declined to be named, citing the sensitivity of the situation.
Duke and Exelon, two of the largest US utilities, could not immediately be reached for comment.
Washington-based NEI said that it supports a diversity of uranium supply, including the development of US facilities to produce and process the fuel.
"While Russia is a significant global supplier of commercial nuclear fuel, US utilities contract with a worldwide network of companies and countries for their fuel requirements to mitigate the risks of potential disruption," said Nima Ashkeboussi, NEI's senior director of fuel and radiation safety.
The Biden administration has said it is working to keep American energy costs low.
"We are listening to all inquiries from industry and will continue to do so as we take measures to hold Russia accountable," a White House official said when asked about the uranium lobbying.
Uranium is used as a fuel inside reactors to achieve nuclear fission to boil water and generate steam that spins turbines to generate electricity.
There is no uranium production or processing in the United States currently, though several companies have said they would like to resume domestic production if they can sign long-term supply contracts with nuclear power producers. Texas and Wyoming have large uranium reserves.
Australia and Canada also have large reserves of uranium and there is ample processing capability there and in Europe. But Russia and its satellites are the cheapest producers.
The US nuclear power industry's use of Russian uranium is likely to spark further questions about where and how the United States procures the materials needed to supply high-tech and renewable-energy products, a dependency that President Joe Biden singled out last week as a national security threat.
Russia's uranium production is controlled by Rosatom, a state-run company formed by Russian President Vladimir Putin in 2007. The company is an important source of revenue for the country.
Former US President Donald Trump in 2020 proposed spending $150 million to create a strategic uranium reserve, and Biden administration officials have expressed support for the idea.
Other utilities around the globe have already begun looking beyond Russia for supply. Swedish power company Vattenfall AB said last week it would stop buying Russian uranium for its nuclear reactors until further notice, citing the Ukrainian conflict.
