Intra-grain Fission Gas Bubble Pressure Determination using Advanced Scanning Electron Microscopy Techniques
It has been hypothesized that grain boundary fission gas is responsible for fuel fragmentation observed in high-burnup fuel under simulated loss-of-coolant accidents. To increase understanding of fission gas’s role, this research used electron microprobe analysis and Monte Carlo simulation to evaluate intra-grain bubble gas content of high-burnup fuel.
