Q&A with Monica Regalbuto: Shaping a sustainable HALEU economy

Regalbuto

High-assay low-enriched uranium (HALEU) is the power-dense feedstock of choice for a slew of advanced reactor designs. There’s just one problem: It isn’t available . . . yet. Downblending high-­enriched uranium owned by the Department of Energy to between 5 and 19.75 percent fissile U-235 is a stopgap measure at best, and no U.S. facility can yet produce commercial quantities of uranium above the 5 percent U-235 limit for low-enriched uranium.

The problem is one not of technology, but of economics: Enrichment companies want to see clear market signals that advanced reactors will be deployed in quantity, leading to long-term purchase agreements that will justify investments made today.

ANS Fellow Monica Regalbuto is director of Nuclear Fuel Cycle Strategy at Idaho National Laboratory, tasked with leveraging her more than 30 years of fuel cycle experience to ensure an adequate domestic supply of HALEU. She was invited to speak about her work during the opening plenary session of the 2021 ANS Winter Meeting.

International nuclear safeguards verification relies on a precise count of isotope particles collected on swipes during International Atomic Energy Agency inspections of nuclear facilities and isolated through a series of lengthy chemical separations that can take about 30 days to complete. On October 15, Oak Ridge National Laboratory—a member of the IAEA’s Network of Analytical Laboratories (NWAL)—announced that analytical chemists at the site have developed a faster way to measure isotopic ratios of uranium and plutonium collected on swipes, which could help IAEA analysts detect the presence of undeclared nuclear activities or material.

For years, pressure has been building for a commercial path to a stable supply of high-assay low-enriched uranium (HALEU)—deemed essential for the deployment of advanced power reactors—but advanced reactor developers and enrichment companies are still watching and waiting. In contrast, the uranium spot price soared after Sprott Physical Uranium Trust, a Canadian investment fund formed in July, began buying up U3O8 supplies, causing the price to increase over 60 percent, topping $50 per pound for the first time since 2012. Fueled by growing acknowledgment that nuclear power is a necessary part of a clean energy future, uranium is the focus of attention from Wall Street to Capitol Hill.

Kazatomprom, Kazakhstan’s state-owned uranium production company, will continue “flexing down” production by 20 percent through 2022, compared to the planned levels under subsoil use contracts, the company announced last week. It will also maintain its 20 percent reduction against subsoil use contracts in 2021, with no additional production planned to replace volumes lost in 2020 due to measures taken to combat COVID-19.

Kazatomprom does not expect to return to full subsoil use contract production levels until a sustained market recovery is evident and demand and supply conditions signal a need for more uranium, the company noted.

A Virginia circuit court judge has upheld the state’s 38-year-old moratorium on uranium mining, rejecting Virginia Uranium Inc.’s (VUI) argument that the ban was an unconstitutional violation of the company’s rights regarding its Coles Hill property. On July 27, Judge Chadwick Dotson ruled in the state’s favor, declaring that while the mining prohibition does amount to a taking or damaging of private property within the meaning of the state constitution, Virginia had a compelling interest to do so.

Record low uranium production noted as Congress debates reserve funding

July 21, 2020, 3:03PMNuclear News

Uranium producers around the world have suffered through years of record low uranium prices. In 2019 the United States recorded its lowest total uranium production—174,000 lb U3O8—since the U.S. Energy Information Administration began collecting data in 1949, according to the agency’s Today in Energy analysis of July 17.

U.S. uranium producers asked the federal government to come to their aid in January 2018, and President Donald Trump created the U.S. Nuclear Fuel Working Group (NFWG) in July 2019. While the NFWG issued a report in April 2020 recommending support for the front end of the nuclear fuel cycle, uranium producers are in a waiting game once again as the U.S. House of Representatives works on Fiscal Year 2021 appropriations legislation.
