Abstract
In order to determine the concentration of uranium and plutonium in 1AP of bench experiment in time ,an on-line X-ray fluorescence spectrometer was designed and set up ,and the angle between incident X-ray and emitted X-ray was 60° .The spectrom-eter was airproofed in order to protect the X-ray tube and the detector .Based on the plotted working curve of uranium and plutonium ,the analytical method was established to determine the concentration of uranium and plutonium in 1AP .The relative standard deviation of the measured concentration of uranium is 0.42% . T he relative range for repeated measurement of uranium concentration in three hours is 1.6% . T he results show that the device is stable enough .This spectrometer was applied in on-line determi-nation of uranium .It can monitor the fluctuation of uranium concentration ,and the results agree well with that of titration means .关键词
