Outline of Final Research Achievements

Basic research for constructing rational treatment and disposal system of radioactive wastes generated by Fukushima Dai-ichi nuclear accident have been performed in three research fields of characteristic of solid and liquid contaminants, treatments of solid and liquid contaminants, and radioactive waste disposal.
As a result, we have obtained many useful data on properties of fuel debris, leaching behavior of nuclides from debris, treatment methods of contaminated water, solidification method of wastes, novel decontamination methods, migration behavior of nuclides in the fields containing salts of high concentrations, and so on. These results are expected to contribute to the management plan of radioactive wastes generated under abnormal conditions in contact with water containing seawater in the Fukushima Dai-ichi nuclear accident, and to the progress of radioactive waste managements.
