Modeling of hydrogen reactive-diffusive transport and inventory in porous media with mixed materials deposited layers

摘要

Hydrogen isotopes (His) retention is a key issue for fusion devices like ITER. Simultaneous use of Be, W and C as the wall material for different parts of plasma-facing components (PFCs) will bring in material mixing issues, which compound that of hydrogen isotopes retention. To simulate the hydrogen inventory in the PFGs, we have developed a flexible standalone model. The particle balance model for reaction-diffusion and hydrogen isotope retention in metal and porous media is presented, respectively. However, in this paper, we only present some basic results based on experimental data available for the purpose of validating the model. More targeted experiments are needed to provide necessary input data for this newly developed model.
