摘要：

Atomistic computer simulation in combination with a simple statistical mechanics treatment is used to investigate the importance of Xe concentration for the behaviour of single atoms of Xe in UO2 at low Xe doses. The calculated results are compared to existing experimental data in an attempt to provide an atomistic picture of some of the important factors underlying the diffusion of single atoms of Xe.
