Characteristics of the fine produced during the reprocessing of the spent fuel in the Rokkasho Reprocessing Plant are inevitable data to understand the behavior of the fine in the glass melter. It is also necessary to obtain the characteristic data of the fine to judge the validity of vitrification tests with simulated fine in KMOC facility. The property measurements and chemical reaction tests with simulated fine are valuable to obtain fundamental data that is necessary for the development of a new type of glass melter. With these objectives, the fine was transported from the Rokkasho Reprocessing Plant to the Tokai Research Center of the Japan Atomic Energy Agency and the fine and simulated fine were characterized.
