NSUF 17-CINR-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 toolby using in-situ ion irradiation of UO2 to quantify the effect of irradiation on grain growth. This work willinvestigate the hypothesis that irradiation assisted grain growth is caused by the thermal spike resultingfrom atom collisions. The model added to MARMOT will couple the existing grain growth model to aheat conduction simulation using a stochastic heat source describing the thermal spike.
