【摘要】 为解决核设施退役过程中产生的桶装放射性废物活度非破坏测量,在某几何条件下,废物桶内分布条件为理想情况以及部分条件为理想情况下,利用蒙特卡罗方法改变某些变量对探测效率进行了计算,并对结果进行了分析,给出了废物桶内非理想分布条件简化成理想分布条件的方法,进而提出了桶装放射性废物非破坏测量模式及探测效率获取方法。并用此方法进行了简单的比对实验,实验结果表明该方法是可行的。更多还原

【Abstract】 To set up a non-destructive assay mode for barreled radwaste brought by the process of getting nuclear establishment out of mission,some variables were changed using the Monte-Carlo method to calculate the detecting efficiency when the distributing condition was ideal or partly ideal. The calculation result was analyzed to obtain a method to transform nonideal distributing condition to ideal distributing condition. A non-destructive assay mode for barreled radwaste and a method of getting the detecting efficiency were put forward. The comparison of calculating and experimental results indicates that this method is feasible.更多还原
