| Research Abstract |
Behavior of tritium permeation through paint membranes was experimentally investigated for clarification of mechanism of tritium transfer through hydrophobic paints coated on a concrete material. From the results of measurement of tritium permeation rates, it was found that tritium permeated through epoxy and urethane paint membranes as the form of a HTO molecule, and that diffusion in their paints was the rate-determining step. The permeation rates through concrete materials coated with the paints were much slower than those through the paints only. Hence, resistance of tritium diffusion through interface between a concrete material and paint was clarified to be most effective in the overall tritium transfer process.
