Abstract
The microstructure of fresh MOX fuel pellet is mainly composed of low, medium and high plutonium enriched zones, which is characteristic of MOX fabricated by the Micronized MASterblend (MIMAS) process. It is considered that such kind of microstructure has a major influence on the fission gas behavior in MOX fuel. Fission gas release values were measured by means of puncture test and 85Kr gamma spectrometry. The distribution of the fission product Xe and Cs in MOX fuel pellet were measured by the Electron Probe MicroAnalysis (EPMA) technique.
Using irradiation data, the kinetics of fission gas atoms are examined and discussed in this paper in order to contribute to the improvement of MOX fuel performance in LWRs.
