Abstract

Abstract

PROFIP5 was used to analyze the effects of linear heat rate,decay constant and defect size on fission product fraction release.Conclusions about fission product release were drawn:at temperature below 1000℃,the release fractions are independent of temperature;at temperature above 1000℃,the release fractions increase with the temperature;For the same chemical species,the release fractions decrease as the decay constants increase,and this phenomenon is more obvious as the linear heat rate increases.
