PIKETON, Ohio (AP) — Uranium enrichment is getting underway this week at a facility in southern Ohio, a federally authorized demonstration project considered critical to produce the type of fuel needed for newer, more efficient nuclear reactors. That form of uranium contains far more of the isotope U-235 than is typically found in current nuclear reactor fuel. The 3,800-acre (1,500 hectare) site was where uranium had been enriched until 2001 at the Portsmouth Gaseous Diffusion Plant. Poneman said the U.S. has since become the world's biggest importer of enriched uranium. Cleanup and decontamination of the Portsmouth plant are continuing.

WASHINGTON, March 1 (Reuters) - Dow Inc (DOW.N) and private company X-energy said on Wednesday they have agreed to develop and demonstrate the first grid-scale next-generation nuclear reactor for an industrial site in North America. The X-energy Xe-100 plant featuring four high-temperature, gas-cooled reactors is set to be built at one of Dow's sites on the U.S. Gulf Coast. Backers of next-generation nuclear reactors, including the Biden administration, say the technology is crucial to fight climate change. The X-energy plant will provide a Dow facility with process heat and power to make products. Dow, a chemicals company, makes a wide variety of products including polyethylene used in packaging, paints, and foams.
The fuel, called high assay low enriched uranium, or HALEU, is enriched up to 20%, much above the up to 5% level today's reactors use. "TerraPower is anticipating a minimum of a two-year delay to being able to bring the Natrium reactor into operation," he said. The Department of Energy (DOE) is looking to downblend some of its stockpile of weapons-grade uranium to help provide fuel for the reactor projects. Levesque said TerraPower will provide a schedule update next year when it knows more about HALEU supply including the availability of DOE material for downblending. Only one company outside Russia, U.S.-based Centrus Energy Corp (LEU.A) is licensed to produce the fuel but it is years away from making commercial amounts.

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. But only TENEX, which is part of Russian state-owned nuclear energy company Rosatom, sells HALEU commercially at the moment. And this chicken and egg conundrum is complicating the smooth development of HALEU supply. "A reliable HALEU supply is one of many factors under consideration," the company said in an emailed statement.
