    Two examples of how the measured fission gas isotopic composition can be used in the study of fission gas release phenomena are given. In the first example the ratios of Kr85/Kr86 in released and retained gas are used for calculation of the "average time" when the gas was released. This "average time" may be used in code qualification. In the second example the degree of conversion of unstable Xe135 to stable Xe136 is derived from the measured ratio of Xe136 to Xe131+Xe132. This
    conversion is of importance in the calculation of the total Xe generation during irradiation.
