NEUP CINR-17-12797: In-Situ Ion Irradiation to Add Irradiation Assisted Grain Growth to the MARMOT Tool

In this project, we will add the capability to model irradiation assisted grain growth to the MARMOT tool by using in-situ ion irradiation of UO2 to quantify the effect of irradiation on grain growth. This work will investigate the hypothesis that irradiation assisted grain growth is caused by thermal spikes resulting from atom collisions. The model added to MARMOT will couple existing grain growth model to a heat conduction simulation using a stochastic heat source describing the thermal spike.
