Factors underlying nuclear fuel swelling seen at nanoscale for first time
Understanding factors that drive nuclear fuel swelling will help engineers develop higher performance fuels, which could be even safer and more efficient than those used in current nuclear energy plants. As uranium atoms split to produce energy, fission products build up within fuel rods, which impacts nuclear fuel performance inside a reactor. But, a clear picture of the size and location of these solid fission products has been elusive until now.
Junior researchers showing world the way to advanced nuclear fuel design
Two early-career Idaho National Laboratory researchers are earning international attention for their groundbreaking work. They're getting a long-sought look into the 3-D microstructure of irradiated nuclear fuel, then feeding that data into cutting-edge fuel behavior models. Their work will make the design and testing of even safer nuclear fuels more informed and efficient.
A model for success
Idaho National Laboratory researcher Blaise Collin works with software called PARFUME (particle fuel model) as part of an effort to find new, safer fuel sources for use in nuclear reactors.
Industry research: Experiment enters next stage at new Idaho hot cell
To the average eye, the experimental specimens don't look like much: silver-colored squares about the size of a domino. But the samples represent several big milestones for Idaho National Laboratory, the Department of Energy and the US nuclear energy industry. The irradiated 'compact tension' specimens are the first to undergo analysis in a specialized test rig at INL. Plus, they're part of a first-of-its-kind collaboration through the DOE's Advanced Test Reactor National Scientific User Facility.
