Description

The atom ratios of Pu/U, 134Cs/137Cs and 154Eu/137Cs of all the spent fuel assemblies in the full-core of JPDR-1 were calculated. These results were examined through comparison with the values measured by nondestructive γ-ray spectrometry. There were some differences between the calculated and the measured atom ratios of Pu/U and burnup. The calculated atom ratios of 134Cs/137Cs and 154Eu/137Cs were slightly less than the measured values for almost all the fuel assemblies. The most probable production amount of Pu, estimated on the basis of the calculated and the measured atom ratios and their accuracies, agreed well with the amount recovered from the reprocessed fuel assemblies.
