Popis: | A dynamic method to study the release of fission gases from UO2 fuel during low temperature irradiation is presented. The agreement of the dynamic analysis with the experimental results gives further confirmation of the theory based on a defect-trap model and the knock-out process. It supports also the assumptions that gas in an intermediate state exists side by side with the dissolved fission gas and that trapped in bubbles during fissioning. The dynamic method gives a satisfactory qualitative and quantitative interpretation of the transient fission gas release for a step function of fission rate. The qualitative results of the osculating experiments are in good agreement with the results of the dynamic study. |
