Another piece of the plan for meeting the urgent need for high-assay low-enriched uranium (HALEU) to fuel advanced reactor deployments fell into place when the Department of Energy held an Industry Day on October 14. Attendees were asked how soon they could deliver 25 metric tons per year of HALEU enriched in the United States from newly mined uranium. Offtake contracts for six or more years of HALEU production at that rate could be used to stock a DOE-owned HALEU bank to “support [HALEU] availability for civilian domestic research, development, demonstration, and commercial use.”

Five years after bankruptcy, Pennsylvania-based Westinghouse is being sold again, this time with a 49 percent share going to Cameco Corp., the front-end uranium mining, milling, and conversion company headquartered in Saskatchewan, Canada. Cameco and Brookfield Business Partners, based in Toronto, Ontario, announced the deal yesterday. Once it closes as expected, in the second half of 2023, Brookfield Renewable Partners and other Brookfield institutional partners will own a 51 percent interest in a consortium with Cameco.
The DOE and a contractor recently succeeded in disposing of Oak Ridge’s low-activity U-233, but not before recovering Th-229 from the material.

This past October, the Department of Energy’s Oak Ridge Office of Environmental Management (OREM) and its contractor Isotek successfully completed processing and disposing the low-dose inventory of uranium-233 stored at Oak Ridge National Laboratory (ORNL), ending a two-year effort that has eliminated a portion of the site’s legacy nuclear material and provided rare nuclear isotopes for next-generation cancer treatment research.

Citing “improving market sentiment,” Tim Gitzel, president and chief executive officer of the Canadian uranium mining company Cameco, announced on February 9 the planned restart of operations at the McArthur River mine in Saskatchewan.

The ANS Fuel Cycle and Waste Management Division will present a webinar today at noon EST (the recording will be available via the webinar archive to all ANS members) featuring an international panel of experts on nuclear waste reprocessing. The panel will explore the idea of separating certain radionuclides from waste using recycling technology that enables pure materials to be used for other purposes.

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.
The American Nuclear Society wrote to Congress, urging the need for a domestic supply of high-assay, low-enriched uranium.
September 15, 2021, 3:42PMUpdated September 15, 2021, 3:43PMPress Releases The United States Congress needs to take swift action to build a domestic supply of fuel for advanced reactors and to avoid future dependence on Russia for advanced nuclear fuel, the American Nuclear Society wrote in a Sept. 14 letter to the U.S. Senate Energy and Natural Resources Committee.

While it has been known for decades that bacteria known as Geobacter could clean up uranium waste, researchers at Michigan State University recently uncovered the biological mechanism behind the bacteria’s ability to do it.

Is isotope science all sweetness and light? Recent headlines on research confirming the sweet taste of heavy water and the creation of the lightest isotope of uranium yet may give that impression. But the serious science behind these separate research findings has implications for human health and for the understanding of the process of alpha decay.
