79Se、93Zr、107Pd是燃耗测量用的重要核素,为研究它们的精密分析方法,需制备放化纯的样品。79Se、93Zr、107Pd主要存在于乏燃料后处理的高放废液中,由于这些核素在HLLW中含量低(仅为10-9～10-6量级),因此,欲获得足够量的样品,所处理的高放废液量较多。为解决放射性操作剂量大的难题,本研究建立了一套从HLLW中系统分离79Se、93Zr、107Pd的自动化装置。
79Se, 93Zr, 107Pd are important nuclides for fuel consumption measurement. To study their precision analysis methods, pure radiochemical samples should be prepared. 79Se, 93Zr and 107Pd are mainly found in spent spent fuel reprocessing HLB. Due to the low content of these nuclides in HLLW (only 10-9 ~ 10-6), it is necessary to obtain a sufficient amount of sample , The amount of high-level waste handled by more. In order to solve the problem of large dose of radioactive operation, a set of automated system for separating 79Se, 93Zr, 107Pd from HLLW system was established.
