A meso-mechanical model is established for the homogenized irradiation swelling of U-10Mo/Zr dispersion fuels. with an equivalent sphere chosen as the representative volume element (RVE). In the simulation. a mechanistic model for the fission gas swelling of U-10Mo particles and the creep model for Zr matrix with different values of the creep amplification factor are included. https://www.knowall.blog/
