【摘要】 对称性是武器用钚部件的重要属性。从武器上拆卸下的钚部件通常装在特定的密封容器罐内,当具有轴对称结构的钚部件的对称轴与容器罐的对称轴重合时,容器罐外的γ辐射场分布具有轴对称性。钚部件的对称轴与容器罐的对称轴一定程度的偏离会造成容器罐外γ辐射场分布发生变化,从而导致对钚部件的误判。本工作理论模拟了两轴偏离情况下容器罐外γ辐射场的分布情况,研究了偏离程度对钚部件对称性判断的影响。更多还原

【Abstract】 The symmetric attribute is an important attribute of plutonium component in weapon generally installed in sealed container.When the symmetry axis of plutonium component coincides with that of container,the radiation distribution is cylindrical.The radiation distribution out of the sealed container is dissimilarity when symmetry axis is departure,and the estimation is consequently inaccuracy.The radiation distribution in theory was simulated,and the effect of eccentricity was investigated.更多还原
