| Abstract Scope |
High-density fuels (HDF) provide significantly higher uranium density compared to conventional uranium dioxide. Previous HDF research has explored the oxidative behavior of U3Si2, UN, UC, and UB2. Steam oxidation of U3Si2 reveals formation of UO2 and a hydride. However, the interaction between other HDFs and hydrogen remains understudied. Our present study employs the Sieverts technique to detect hydrogen absorption, monitoring pressure variations during HDF interaction. A residual gas analyzer integrated with the Sieverts apparatus enables analysis of potential gas-phase reaction products. The resulting diffraction data undergo Rietveld refinement for unit cell expansion determination and reaction products undergo LECO elemental analysis. Experimental results span 100 to 500 °C, pressures up to two atmospheres, and dwell times of 24 to 96 hours. |
