我国有一定数量的高品质核材料存在于非均匀的残余物料中,需要无损分析方法确定其中~(235)U和钚的含量。这些核材料分布在不同地点的核设施内。1992年度开始,我们接受能源部核材料管制办公室下达的任务,建立一个用于核材料无损分析的流动实验室,研究开发巡回测量设备和技术。以便采用一套设备解决多个核设施,多种非均匀残 In our country, a certain amount of high-quality nuclear materials exist in the non-uniform residual materials. Non-destructive analysis is needed to determine the content of ~ (235) U and plutonium. These nuclear materials are distributed in nuclear facilities in different locations. From the beginning of 1992, we accepted the mandate given by the Office of Nuclear Material Control of the Department of Energy to establish a mobile laboratory for the non-destructive analysis of nuclear materials and to research and develop roving measurement equipment and technologies. In order to use a set of equipment to solve multiple nuclear facilities, a variety of non-uniform residue
