如何测定核设施工艺设备内的滞留量一直是核材料衡算过程中的技术难题,因而直接影响核材料生产过程的闭合衡算,同时也是一个重要的不安全因素。不同的工艺过程、设备和设施环境,以及现场各种变化因素,都会使测量与分析的难度增加。 本课题组针对某工艺过程,经过现场调查,确定了 How to determine the amount of hold-up in the process equipment of a nuclear facility has always been a technical challenge in the accounting of nuclear materials, and thus has a direct impact on the closing balance of the production process of nuclear material, which is also an important factor of insecurity. Different processes, equipment and facility environments, as well as various field variations, make it more difficult to measure and analyze. The research group for a process, after a site survey, identified
