Russian Research Team Synthesizes Novel Metal-Organic Framework Material Capable of Immobilizing Radioactive Cesium

The Frumkin Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences has synthesized a novel metal-organic framework material containing neptunium and cesium atoms. Research shows that this material is insoluble in water, resistant to high temperatures and intense radiation, and can stably "lock" radioactive cesium within its own structure, offering new insights for research on radionuclide immobilization and radioactive waste treatment materials. Metal-organic framework materials are a class of materials with high porosity and controllable crystal structures, whose lattices are typically composed of metal atoms connected by organic molecules. Since their pore sizes and structures can be tuned at the molecular level, these materials can be used to adsorb gases or specific nuclides. However, compared with traditional adsorbents such as activated carbon...

U.S. Completes Mechanical Property Measurements of Irradiated HALEU TRISO Fuel Particles

Researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) have completed mechanical property measurements of irradiated high-assay low-enriched uranium (HALEU) TRISO fuel particles, providing new experimental data for the development and qualification of next-generation nuclear fuels. This is an optical cross-sectional image of an irradiated AGR-2 TRISO fuel particle in the Irradiated Fuels Examination Laboratory at Oak Ridge National Laboratory. Image credit: Oak Ridge National Laboratory, U.S. Department of Energy. TRISO fuel, or tri-structural isotropic fuel, features particles coated with multiple protective layers, typically including pyrolytic carbon layers and a silicon carbide layer. This structure provides strong fission product retention capability and is considered one of the key fuel options for advanced reactors, particularly high-temperature gas-cooled reactors. Understanding the property changes of these coatings after irradiation is a critical step in predicting fuel performance under reactor operating conditions.
