Determination of the isotopic ratios Xe131/Xe134 in the cover gas of KNK II (Leaker phase from 6. 4. to 2. 5. 85)
Description
The Institute of Hot Chemistry of the Nuclear Research Center Karlsruhe has developed an experimental method to determine the ratios of noble fission gases in the ppm range with uncertainties of a few percent. This is especially of interest for the Xenon isotopes 131 and 134, the ratio of which is different for U235 and Pu239 fission. For KNK II with the Uranium/Plutonium fuel of the test zone assemblies and the Uranium fuel of the driver zone assemblies, a comparison of measured and calculated ratios could therefore allow to distinguish between a failure in one of the two zones with different fuel type. In this report the experimental method is explained and experimental results are presented for one special fuel failure in KNK II
