The Fukushima Dai-ichi Nuclear Power Plant accident has resulted in a large amount of radioactively contaminated concrete. As fundamental basis for developing the treatment and disposal concept for these wastes, migration behavior of radionuclides in concrete was investigated. Sorption and diffusion characteristics of tritiated water, cesium, iodine and uranium were measured at various conditions (concrete types, salinity, etc.).
