乏燃料的裂变产物中,放射性钌(Ru)产额较高,因此在核燃料后处理中要予以关注。故本工作研究Pu纯化循环中相接触时间、相比、硝酸浓度对微量钌分配比的影响并通过台架试验研究了流比、料液酸度、洗涤级数、萃取级数、铀浓度对Ru净化的影响。结果表明:流比(2AF﹕2AX)、料液(2AF)HNO3浓度、洗涤级数、萃取级数、铀饱和度对Ru的净化具有显著的影响。并通过台
Of the spent fuel fission products, which have higher yields of radioactive ruthenium (Ru), attention should be given to nuclear fuel reprocessing. Therefore, the study of the Pu purification cycle contact time, compared to the concentration of nitric acid on the distribution of ruthenium ruthenium ratio and through the bench test of the flow ratio, the acidity of the material, the washing series, the extraction series, uranium concentration of Ru Purification effects. The results showed that the flow ratio (2AF: 2AX), the concentration of HNO3 in the feed solution (2AF), the washing order, the extraction order and the uranium saturation had a significant effect on the purification of Ru. And through Taiwan
