| Outline of Final Research Achievements |
The thermal conductivity of the molten glass of solidification of radioactive waste is measured by inversion and ultra-short time laser flash method. In the method, The laser pulse is irradiated to the bottom surface of the thin platinum cells. The temperature response of the surface is measured by the infrared ray detector. The model to reveal relation of the structure of melts and thermal conductivity are developed. A random network model represents the decrease of thermal conductivity by breaking network in melts. A model considering large complex silicate ion shows the more successful result. The effect of cation in melts is also considered.
