Research Abstract

There is possibility in that tritium is accidentally released from a fusion reactor chamber to the inside of concrete building. Even in case of the accidental tritium release, we need to keep safety of fusion reactor system and to minimize tritium leak through porous concrete walls to the environment. In the present study, we experimentally determined tritium transfer(adsorption and diffusion) rates to porous concrete pellets and tritium release rates by a water dissolution method. The rates were analyzed in terms of diffusion model. In addition, a technique to protect tritium permeating through hydrophobic paints such as acrylic-silicon or epoxy paints is developed and its rates were experimentally determined.
