Abstract The phase field model development effort aimed to foster collaboration in the area of mesoscale modeling of irradiation-induced microstructure evolution in reactor materials, with emphasis on bringing the phase-field modeling capabilities into this important field. The model problem chosen for this collaboration among three CMSN team members is the problem of nucleation and growth of voids. Like all other microstructure and microchemical evolution processes in irradiated materials, especially alloys, void nucleation and growth is driven by the intense generation of point defects under neutron irradiation, and by the long-range diffusion and interactions of these defects.
