The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

The Department of Energy announced March 31 that a new Molten Salt Flow Loop Test Bed at Idaho National Laboratory recently went through its inaugural test run. The closed-loop test system will allow for continuous monitoring and analysis of chloride-based molten salt reactor technology and instruments before the construction of the Southern Company/TerraPower Molten Chloride Reactor Experiment. MCRE—an experimental fast-spectrum molten salt research reactor—will be built at INL’s repurposed Zero Power Physics Reactor, which has been renamed LOTUS (Laboratory for Operation and Testing in the United States).

Savannah River National Laboratory said it has received a patent for its radially oriented honeycomb structures. The technology offers a solution to the deformation of cylindrical honeycomb structures when they are formed from flat panels, providing a way to create structures with greater wall thickness than traditional methods.

Scientists at Idaho National Laboratory continue to make progress on the Molten Chloride Reactor Experiment (MCRE), which entails research and development for the first operational advanced nuclear reactor to use a mixture of molten chloride salt and uranium as fuel and coolant. The experiment is evaluating the safety and physics of the molten chloride fast reactor that Southern Company and TerraPower are planning to build.

A team from Idaho National Laboratory and the Department of Energy’s Office of Nuclear Energy recently visited Carolina Fabricators Inc. (CFI) in West Columbia, S.C., to launch the fabrication process for the primary coolant system of the MARVEL microreactor. Battelle Energy Alliance, which manages INL, awarded the CFI contract in January.

The sample chamber is equipped with a robotic arm capable of precisely positioning and orienting samples within the pulsed thermal neutron beam originating from the spallation target. This advanced setup enables simultaneous neutron diffraction and Bragg-edge imaging, allowing researchers to analyze the structural and microstructural properties of irradiated nuclear fuels under controlled conditions.

In materials science, understanding the unseen—how materials behave internally under real-world conditions—has always been key to developing new materials and accelerating innovative technologies to market. Moreover, the tools that allow us to see into this invisible world of materials have often been game-changers. Among these, neutron imaging stands out as a uniquely powerful method for investigating the internal structure and behavior of materials without having to alter or destroy the sample. By harnessing the unique properties of neutrons, researchers can uncover the hidden behavior of materials, providing insights essential for advancing nuclear materials and technologies.

New Strategic Understanding for Premier Education and Research (SUPER) agreements signed by Idaho National Laboratory, Boise State University, and University of Idaho will foster collaboration among the institutions in advanced energy and cybersecurity projects. The five-year agreements are designed to open doors for research and development opportunities, while advancing existing research and development initiatives, including projects in nuclear energy and high-performance computing.

Ontario Power Generation in Canada announced that Unit 1 of its Darlington nuclear power plant, which has returned to service from refurbishment, is now producing the medical isotope cobalt-60. During refurbishment activities, OPG made modifications to the unit to allow it to produce Co-60, which is used to sterilize 30 percent of the world’s single-use medical devices, such as syringes, gloves, and implants.
