| Abstract Scope |
In recent years, uranium borides have emerged as promising candidate fuel forms due to their high thermal conductivity, high melting points, high uranium density, and potential dual functionality as both fuel and burnable absorbers. This work investigates the synthesis, structural behavior, and oxidation resistance of uranium borides and chromium-alloyed uranium borides. The temperature-dependent structural evolution of these materials was characterized using in situ synchrotron X-ray powder diffraction and X-ray absorption fine structure spectroscopy. This talk outlines the methods and challenges associated with synthesizing uranium borides and chromium-alloyed uranium borides, and evaluates their thermophysical properties and oxidation behavior, providing insights into their potential as advanced nuclear fuel forms. |
