In a first for the Department of Energy’s Oak Ridge Site, a former reactor facility is being demolished. The site’s cleanup contractor, UCOR, began tearing down the Bulk Shielding Reactor, also known as Building 3010, last week.
“While this project is not the biggest demolition we’ve undertaken, it carries a lot of significance,” said Laura Wilkerson, acting manager for the Oak Ridge Office of the DOE’s Office of Environmental Management (EM). “It is the first removal of a former reactor at [Oak Ridge National Laboratory], and it is a signal of much more to come at the site in the immediate future.”

Research with the Department of Energy’s Thomas Jefferson National Accelerator Facility (Jefferson Lab) has revealed new insights into short-range correlations—the brief pairings of nucleons (protons with neutrons, protons with protons, or neutrons with neutrons) in the nuclei of atoms. The study, published in Nature, used precision measurements to determine that short-range correlations differ depending on the density of the nucleus, that is, how many nucleons it contains.

Nagra, Switzerland’s national cooperative for the disposal of radioactive waste, has announced that it has selected Nördlich Lägern as the site for a deep geological repository for radioactive waste. According to Nagra, extensive investigations have shown that Nördlich Lägern, located in northern Switzerland near the German border, is the most suitable area for a geologic repository with the best overall safety reserves.

The Nuclear Regulatory Commission yesterday announced that it has issued a renewed license for Westinghouse Electric Company’s Columbia Fuel Fabrication Facility (CFFF), authorizing operations at the plant for another 40 years—through September 12, 2062.
Located in Hopkins, S.C., the CFFF manufactures fuel rods for use in commercial nuclear reactors. According to Westinghouse, 10 percent of the nation’s electricity comes from the fuel manufactured at the facility.

Scientists in the Departments of Radiation Oncology and Medicine at the University of Washington (UW) and Fred Hutchinson Cancer Center (Fred Hutch) are directly targeting cancerous cells traveling through patients’ bloodstreams with diseases such as leukemia and lymphoma using an intravenous injection of the radioactive isotope astatine-211 (At-211). The work, its challenges, and its promise were described in a recent news release from the National Isotope Development Center (NIDC), which is managed by the Department of Energy’s Isotope Program.

Maybe hold off commenting on those Palisades decommissioning plans for now: Michigan Gov. Gretchen Whitmer last Friday penned a letter to energy secretary Jennifer Granholm pledging state support for a Holtec International plan to restart the recently shuttered Palisades nuclear plant in Covert, Mich. It was Whitmer’s second letter to the Department of Energy head expressing support for Palisades and touting its value to the state.

The Nuclear Regulatory Commission has made Holtec International’s post-shutdown decommissioning activities report (PSDAR) for the closed Palisades nuclear power plant available for public comment until December 27. The NRC also plans to hold a public meeting to discuss the report on the evening of September 22 at the South Haven campus of Lake Michigan College, about 10 miles north of the Palisades site in Covert, Mich.

Research by scientists at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and collaborating institutions has the potential to improve plasma performance in tokamak nuclear fusion reactors, according to a recent paper in Nuclear Fusion. The research focused on the use of a PPPL-developed dropper to apply coatings of boron powder to the tungsten components inside a tokamak, thereby helping protect the tungsten against the intensely hot plasma. According to lead author Grant Bodner, this process offers “a way to deposit boron coatings without turning off the tokamaks’ magnetic field.”

Those who welcomed the $700 million earmarked for high-assay low-enriched uranium (HALEU) supply in the Inflation Reduction Act of 2022 (IRA) in August have cause to celebrate again. The White House sent a supplemental appropriation request to Congress on September 2 that would provide more than double the IRA funds if passed—$1.5 billion—for the Department of Energy’s Office of Nuclear Energy to build a reliable supply of both low-enriched uranium for existing U.S. nuclear power plants and HALEU for the advanced reactors that will be built within the decade.

Just one week after entering into an exclusive agreement with a Dutch nuclear development company to deploy small modular reactors in the Netherlands, U.K.-based Rolls-Royce SMR has announced the signing of a memorandum of understanding with Škoda JS to explore “areas of collaboration” for SMR deployment in both the Czech Republic and elsewhere in Central Europe.
