Abstract

The validity on the application of nuclear material monitoring using specific emitted radiation was performed in the pyro-process. For application to the process monitoring, the characteristics of each process and the measurable nuclei were analyzed. The main emitted radiation was determined, and the relationship and linearity with the measurement signal were analyzed and evaluated for changes in the nuclear material content and movement. The measurement signal for changes in the 5,10,15,20 % nuclear material content showed linearity in the reduction process, and in the electro refining process, it was possible to detect changes in nuclear material movement (10, 30 %, 50, 70, 90 %) according to time elapse. In the electro winning process, the recovered nuclear material was properly found at the cathode over time. From the simulation, monitoring the content change for plutonium will be possible, and the application of process monitoring through radiation measurement will contribute to the efficiency of nuclear material monitoring and process transparency.

利用辐射测量法监测高温核过程的可行性

在热工过程中验证了利用特定辐射监测核材料的有效性。为了应用于过程监测，分析了各过程的特征和可测核。确定了主要发射辐射，并分析了与测量信号的关系和线性关系，评价了核物质含量和运动的变化。在还原过程中，5、10、15、20%核物质含量变化的测量信号呈线性，在电精炼过程中，可以根据时间推移检测到核物质的移动变化（10、30%、50、70、90%）。在电致胜过程中，随着时间的推移，回收的核材料在阴极被适当地发现。从模拟结果来看，监测钚的含量变化将成为可能，通过辐射测量进行过程监测的应用将有助于提高核材料监测的效率和过程透明度。
