MATRIXES FOR IMMOBILIZATION OF THE RADIOACTIVE WASTE AND COMPARATIVE ANALYSIS THEIR PHYSICOCHEMICAL AND TECHNICAL CHARACTERISTICS

摘要

The problem of the immobilization of the radioactive waste is one of the important problems for the nuclear industry and all mankind’s.The most reliable method is the inclusion of waste in glassy or mineral-like matrix.The process of the vitrifying of the radioactive waste is composite owing to high requirements shown to matrixes and to process of the vitrifying of waste. rnMatrixes with the included radioactive waste should be chemically,thermally and radiation stable.Processes of their vitrifying should be reliable,technically simple,as they carried out at distance control.Different glassy and mineral-like systems and technical possibilities of the radioactive waste vitrifying processes realizing are briefly reviewed in the given report.
