[3K02] Demonstration research on fast reactor recycling using low decontaminated MA-bearing MOX fuels

Keywords:MOX, simulated FP, sintering, shrinkage rate

Nd2O3 and Sm2O3 were added to MOX as simulated FP, and their effects on sintering behaviors were evaluated by dilatometer.
Sintering shrinkage was observed from around 1000 ℃ and the peak of shrinkage rate shifted to the higher temperature side as the addition rate increased. On the other hand, no effect was observed on the final density after sintering; all showed similar values.
