Description

Highlights: • The activity of 158Tb measurements using gamma-ray spectrometry. • Uncertainty of determination of 158Tb in the nuclear reactor waste. • SCALE 6.1 modeling of radionuclide production in the RBMK-1500 reactor. • Establishment of the origin of 158Tb and other observed gamma-ray emitters in the RBMK-1500 radioactive waste. - Abstract: The activity of 158Tb was measured in waste samples from the Ignalina NPP Unit I RBMK-1500 reactor using gamma-ray spectrometry. The origin of 158Tb and the other observed gamma-ray emitters has been studied by using SCALE 6.1 modeling and comparing radionuclide ratios in the RBMK-1500 radioactive waste. The results of the calculation of the massic activity of gamma-ray emitters were used for interpretation of the total gamma-ray spectrum and the determination of 158Tb massic activity uncertainty in the waste of RBMK-1500.
