| 摘 要： | 推导出了一个相干扩散方程用来研究核燃料边缘位置处氙原子沿着位错线的运动规律,并给出了促使其扩散的微观物理机制,研究了氙气泡在材料中的生长受限行为.利用这种含时的有限扩散技术,可以数值计算张力相干扩散过程,进而给出氙原子沿着位错线的扩散性质.结果表明:氙原子沿着位错线的运动是随着驱动能线性变化的,同时,给出了燃料中边缘位置氙气泡无法长大的物理原因. |

| Abstract: | We give a coherent diffuse equation to study the behaviors of Xenon atom along the dislocation and the Xenon bubble movement mechanism in the UO2 nuclear Fuel boundary, at the same time, we study the Xenon bubble growth behavior. By using a time-dependent finite-difference technique, we can numerically solve stress coherence diffuse equation and study the transfer properties of Xenon along the dislocation. Our numerical results show that the transport of the xenon atom along dislocation is linear change with the external driven energy, and we give the reason of the growth limit of xenon bubble. |
