Stable noble gas isotopes released from reprocessing plant used for nuclear safeguards
- 1. China Inst. of Atomic Energy, Beijing (China)
Description
The correlations between stable noble gas isotopic ratios and the burnup of spent fuel are calculated by Origen2.1 code. The production of stable Kr, Xe nuclides in reactor fuel and the subsequent dilution of these nuclides in the reprocessing plant stacks are estimated for PWR fuel with a burnup of 30 GWd/tU. 82Kr and 129Xe, at the natural background, are suggested being baseline for subtracting atmospheric parts of the other isotopes in the samples consisting of both fissiongenic and natural noble gas. The nuclide ratios of 83Kr/86Kr, 84Kr/86Kr, 131Xe/134Xe and 132Xe/134Xe near linearly correlated with the burnup of the spent fuel can be used for the nuclear safeguards. (authors)
