"Thermal hydraulics modeling on core melting in severe accidents"

When the severe accident occurs, the direct observation is impossible due
to the severe environment such as high temperature and high radiation dose.
The introduction of numerical simulation techniques is desired for the
analysis of the severe accident The MPS (Moving Particle Semi-implicit)
method is well-known as a feasible method for simulating the violent motion
of free surface fluid flows during the phase transition. However, the
boundary condition was limitted to the Dirichlet boundary in the existing
MPS method. In this study, we developed a new modeling of the Neumann
boundary condition in the MPS method and succeeded the representation of the
melting phenomemon due to the heat flux boundary.


It's a great honor to win this prize. I would like to thank Prof. Mikio
Sakai for his excellent supervision. I'm going to develop new models in the
future to encourage the introduction of the numerical simulations.
