摘要：
A method is developed to verify the U-235 content of TRIGA fresh fuel using gamma-ray spectrometry of the short-lived fission products Zr-97/Nb-97, I-132 and La-140. The short-lived fission-product activities can be established by irradiating the fuel in a nuclear reactor. Based on the measured activities, the U-235 content can be deduced by iterative calculations. The aim of this work is to establish a calibration method for estimating the burnup values of the rod-type spent fuels without the need for detailed data on fuel irradiation history.
