In situ analysis of solid solution formation of CeO$$_{2}$$ and Gd$$_{2}$$O$$_{3}$$

Tsuchimochi, Ryota; Sugata, Hiromasa*; Sunaoshi, Takeo*

Solid solution reaction of MOX pellet procceds at sintering process, but at what temperature and how fast the reaction proceeds have not been understood. CeO$$_{2}$$ and Gd$$_{2}$$O$$_{3}$$ were used as simulating materials of UO$$_{2}$$ and PuO$$_{2}$$, respectively. A shrinkage rate measurement on CeO$$_{2}$$ and Gd$$_{2}$$O$$_{3}$$ mixed compact was carried out in the temperature range of 300K to 1923K. The shringage curve has two positive peaks at around 1213K and 1600K. High temperature X-ray diffraction measurements on CeO$$_{2}$$ and Gd$$_{2}$$O$$_{3}$$ mixed powder were carried out at 1213K and 1600K for 240 minutes. The solid solution formation was observed at 1600K, but not at 1213K. It is considered that the first shrinkage region at 1213K was caused by initial sintering and the second region at 1600K was caused by mid-final sintering.
