摘要

The concept of deep geological disposal of nuclear wastes in the view of both radioactive high-level waste (HLW) occurring during chemical reprocessing the used nuclear fuel and unreprocessed spent fuel (SF) is under intensive investigation in many countries. A decision in favour of high-level nuclear waste disposal will be based on conditioning techniques, in particular encapsulation of HLW and SF in a form suitable for further deep geological emplacement. This paper describes research work to develop and apply solid final waste form in the view of: - immobolizing protective crystalline matrix containing radioactive elements; - monolithic ceramic block in which the spent fuel rods are embedded. The method of hot isostatic pressing (HIP) is used with the aim of obtaining the chemically stable, corrosion resistance and mechanically strong rock-like ceramic, glass-ceramic materials. The results of laboratory scale experiments carried out so far show that these obtained materials may be used as base materials for manufacture of the immobilizing matrixes for HLW isolation and monolithic protective blocks for spent fuel encapsulation. Concept approach, waste form characterization, technological process, equipment characterization are presented.
