Ion irradiation is frequently used to emulate radiation damage to structural materials during reactor operation. The quality of these experiments as a prediction of in-reactor microstructure depends heavily on the ability to account for heightened dose rate and localized damage near a free surface. A spatially dependent cluster dynamics model, which treats the concentrations of defect clusters using a system of mean field reaction rate equations, was developed and utilized to investigate the impact of these phenomena on commercial ferritic alloys as swelling proceeds to high dose. A more detailed qualitative description of dose rate effects can connect both neutron and ion irradiations to a common theoretical foundation that can assist in the design of future experiments.
