粒子焼結による振動充填燃料の熱伝導度の向上効果を調べるため、クリープ試験装置を用いて異なる粒子ネック比のUO2粒子焼結体を製作し、平板比較法熱伝導度測定装置を使用して熱伝導度測定を行った。本試験では、ネック比0%と37%の試料について、600800の範囲で測定を実施した。

Measurement of thermal conductivity of sintered UO2 particle bed was performed to investigate the necking effect on thermal conductivity. Test samples were prepared with high temperature creep test equipment. Plate comparison method was applied to the measurement. Thermal conductivity measurements were done for two neck ratio samples (0% and 37%) under the temperature from 600 to 800 Celsius degrees.
