| Research Abstract |
The present study focuses on dynamic behavior of fuel debris bed, which is critical as a dominant factor in the long-term decay heat removal process aftercore disruptive accident of fast reactors. A particle-based simulation code was developed as a mesoscale analysis method to evaluate fundamental characteristics of fluid-dynamic behavior in fuel debris beds. A small-scale experiment was also performed simulatingsolid-gas-liquid three-phase flows in a solid particle bed, and then the developed method was verified based on experimental results.
