Fission gas release within uranium dioxide nuclear fuel occurs as gas atoms diffuse through grains and arrive at grain boundary (GB) bubbles; these GB bubbles grow and interconnect …
Second phase particles and particle stringers have strong influences on recrystallized grain structure and alloy performances. In this work, the effects of second phase particles on grain …

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 …
In this study we compared the microstructure evolution of U-Mo fuel foils produced with and without heat treatment at low burn-up via advanced post-irradiation examination. The aim of …
A monolithic fuel design based on a U-Mo alloy has been selected as the fuel type for conversion of the US High-Performance Research Reactors. A critical phenomenon of …
