Abstract
The γ-ray spectra of fission gases released from UO2-graphite pellets under neutron irradiation were measured. With and without separating fission gases into xenon and krypton, 25 kinds of γ-ray were observed and assigned to nine nuclides, 85mKr, 87Kr, 88Kr(88Rb), 133Xe, 135Xe, 135mXe and 138Xe (138Cs). A value of 15 min is proposed for the half-life of 138Xe, based on analysis of the decay curves. Discussion is given on problems related to determination of the release rate of each fission product through measurement of the height of each peak in the γ-ray spectrum.Keywords
