初步建立了一台铀钚在线X射线荧光测量仪,目的是对铀钚比为4﹕1的1BP工艺料液进行铀钚浓度在线监测。利用此仪器分别对纯的水相铀、有机相铀和水相钚进行了测量,水相铀、有机相铀、水相钚工作曲线的相关系数分别为R2=0.999、0.998、0.999。对于20g/L以下水相铀、0.5g/L以下水相钚 An uranium-plutonium on-line X-ray fluorescence spectrometer was initially established to monitor the concentration of uranium and plutonium on the 1BP process feed with a uranium-plutonium ratio of 4: 1. Pure uranium, organic phase uranium and aqueous phase plutonium were measured by this instrument respectively. The correlation coefficient of the working curve of uranium, organic uranium and aqueous phase plutonium was R2 = 0.999,0.998,0.999. For the following 20g / L aqueous uranium, 0.5g / L water phase plutonium
