Outline of Final Research Achievements

In this study, in order to propose the proper temporary storage method of radioactive decontamination solid waste, experiments and numerical simulations were carried out, and the effectiveness of air drying the decontamination waste and the effect of piling up height and the filling spaces on the temperature inside a storage site were quantitatively clarified. Moreover, the thermal source positional estimation method in the solid waste layer which had several spots of high temperature locally on the surface was proposed, and the accuracy of the positional estimation by the proposed method was quantitatively clarified through experiments and numerical simulations.
