Abstract Scope |
Uranium-zirconium (U-Zr) is a candidate fuel for nuclear fast reactors. An improved mechanistic understanding of the diffusion and phase behavior of the alloy will allow us to design safer and more efficient fuel. In this work, we apply quantitative phase field simulations based on thermodynamic data to analyze existing diffusion couple data of unirradiated U-Zr and constituent redistribution in irradiated U-Zr fuel rods. We fit various parameters in the models by comparing to the available data. We then use sensitivity analysis to determine which parameters have the largest impact on the simulation predictions, in order to direct future experiments. |
