Research Abstract |
The formation of point defects and their clusters in materials during irradiation is one of key issues for material's degradation in fission and fusion reactors. To understand the mechanism of cluster formation is important for further development of irradiation-resistant materials. In the present study, theoretical investigation was done to model the nucleation and growth process of defect clusters, which provides us the dose-rate dependence of defect cluster formation. These findings obtained here will be useful for establishment of the irradiation correlation rule that is required to predict materials degradation behavior in the realistic irradiation environments of fission and fusion reactors from the material's database already obtained at the existing irradiation facilities.
