Study mapping U-10Zr porosity informs metallic fuel design
Researchers at Idaho National Laboratory and the Massachusetts Institute of Technology have conducted a three-dimensional study of irradiated U-10Zr—uranium alloyed with 10 percent zirconium—across key radial regions, providing new insights into how the material swells, transfers heat, and interacts with the fuel cladding.
U-10Zr was extensively tested in historical sodium-cooled fast reactors and is now attracting attention for use in next-generation advanced reactors.

Validation plays a vital role in building trust in the predictive power of models and computational methods. Validation of a code consists of modeling documented real-world experiments and comparing the code-predicted response to the actual, measured response. In this panel session, we will discuss how these experiments are evaluated as benchmarks and used for validation of nuclear data and computational methods. We will also present an overview of four benchmark projects that aim to document different kinds of real-world experiments, with four panelists who chair the projects: Catherine Percher (LLNL), chair of the International Criticality Safety Benchmark Evaluation Project (ICSBEP), Mark DeHart (INL), chair of the International Reactor Physics Experiment Evaluation Project (IRPhEP), Thomas Miller (ORNL), chair of the Shielding Integral Benchmark and Database (SINBAD), and Germina Ilas (ORNL), chair of the Spent Fuel Composition (SFCompo) project. Additionally, Rowdy Davis (UNM), will present on his experience being a benchmark evaluator for ICSBEP, having recently submitted a benchmark on the University of New Mexico research reactor.
