摘要:Abstract(#br)The study of grain growth kinetics in nano-grained UO 2 samples is reported. Dense nano-grained UO 2 samples with well-controlled stoichiometry and grain size were fabricated using the spark plasma sintering technique. To determine the grain growth kinetics at e...

摘要:Abstract(#br)The radiation-induced amorphization of U 3 Si 2 was investigated by in-situ transmission electron microscopy using 1 MeV Kr ion irradiation. Both arc-melted and sintered U 3 Si 2 specimens were irradiated at room temperature to confirm the similarity in their re...

摘要:Abstract(#br)The microstructure modifications of a high-energy Xe implanted U 3 Si 2 , a promising accident tolerant fuel candidate, were characterized and are reported upon. The U 3 Si 2 pellet was irradiated at Argonne Tandem Linac Accelerator System (ATLAS) by an 84 MeV X...

摘要:Abstract(#br)We have developed a mesoscale phase-field model for studying the effect of recrystallization on gas-bubble-driven swelling in irradiated U-Mo alloy fuel. The model can simulate the microstructural evolution of the intergranular gas bubbles on the grain boundaries as ...

摘要:Abstract(#br)In this study, smaller-grained (hundred nano-meter size grain) and larger-grained (micro-meter size grain) U-10Mo specimens have been irradiated (implanted) with 250 keV Xe + beam and were in situ characterized by TEM. Xe bubbles were not seen in the specimen af...

摘要:Abstract(#br)Rate theory simulations of fission gas behavior in U 3 Si 2 are reported for light water reactor (LWR) steady-state operation scenarios. A model of U 3 Si 2 was developed and implemented into the GRASS-SST code based on available research reactor post-irradiation exa...

摘要:Abstract(#br)To study the steam oxidation behavior of Zircaloy-2, a high-energy synchrotron X-ray diffraction technique was applied to perform an in-situ oxidation measurement. The depth profiles of oxide volume fractions were obtained at both 600 and 800 °C. Multiple layers...

摘要:Abstract(#br)Evolution of porosity generated in metallic U–Zr fuel irradiated in fast spectrum reactors leads to changes in fuel properties and impacts important phenomena such as heat transport and constituent redistribution. The porosity is generated as a result of the acc...
