US looking to replace Russian uranium for operation of latest nuclear reactors

US firms developing a new generation of small nuclear power plants to help cut carbon emissions have a big problem: only one company sells the fuel they need, and it’s Russian, Report informs referring to Reuters.

That's why the US government is urgently looking to use some of its stockpile of weapons-grade uranium to help fuel the new advanced reactors and kick-start an industry it sees as crucial for countries to meet global net-zero emissions goals.

"Production of HALEU is a critical mission and all efforts to increase its production are being evaluated," a spokesperson for the US Department of Energy (DOE) said.

The energy crisis triggered by the war in Ukraine has renewed interest in nuclear power. Backers of smaller, next-generation reactors say they are more efficient, quicker to build, and could turbocharge the shift away from fossil fuels.

But without a reliable source of the high assay low enriched uranium (HALEU) the reactors need, developers worry they won't receive orders for their plants. And without orders, potential producers of the fuel are unlikely to get commercial supply chains up and running to replace the Russian uranium.

"We understand the need for urgent action to incentivize the establishment of a sustainable, market-driven supply of HALEU," the DOE spokesperson said.

The US government is in the final stages of evaluating how much of its inventory of 585.6 tons of highly enriched uranium to allocate to reactors, the spokesperson said.

The fact that Russia has a monopoly on HALEU has long been a concern for Washington but the war in Ukraine has changed the game, as neither the government nor the companies developing the new advanced reactors want to rely on Moscow.

HALEU is enriched to levels of up to 20%, rather than around 5% for the uranium that powers most nuclear plants. But only TENEX, which is part of Russian state-owned nuclear energy company Rosatom, sells HALEU commercially at the moment.

While no Western countries have sanctioned Rosatom over Ukraine, mainly because of its importance to the global nuclear industry, US power plant developers such as X-energy and TerraPower don't want to be dependent on a Russian supply chain.

"We didn't have a fuel problem until a few months ago," said Jeff Navin, director of external affairs at TerraPower, whose chairman is billionaire Bill Gates. "After the invasion of Ukraine, we were not comfortable doing business with Russia."
