In recent years, uranium boride (as a tetraboride and diboride) has been further investigated as a candidate fuel form for its high thermal conductivity, high melting point, high uranium loading, and potential for dual use as a fuel and burnable absorber. In this work, the synthesis, structural behavior, and oxidation behavior of uranium borides and chromium- and yttrium- alloyed uranium borides are investigated. The structure of the synthesized uranium borides and chromium- and yttrium- alloyed uranium borides were probed using synchrotron X- ray Powder Diffraction (XRD) and Pair Distribution Function (PDF) analysis with in-situ heating. The methods and challenges in synthesizing uranium boride and chromium- and yttrium-alloyed uranium boride, as well as the consequential thermophysical and oxidation properties of these potential fuel forms, are elucidated in this work.","abstract_html":"Following the nuclear accident at Fukushima Daiichi Power Station in 2011, an urgent need for safer, more economical, and versatile nuclear fuels has arisen.
