Abstract

Borosilicate glass is used in mixture of high-level radioactive waste (HLW) generated by nuclear spent fuel. Thermophysical property data of borosilicate melts in molten state during processing of HLW were studied to investigate a possibility of a simpler and flexible process for immobilisation of high level wastes. Especially, these data are indispensable information to optimize the process of the temperature distribution in the glass melting furnace. In this study, the thermal effusivity of B₂O₃-CaO-SiO₂ melt was measured using a front heating-front detection laser flash method. The thermal conductivity was evaluated by combining the measured thermal effusivity data with specific heat capacity and density. In these results, the thermal conductivity of CaO-B₂O₃-SiO₂ melt was increased with temperature.
