Abstract: The paper introduces the research on sintering process of UO2-Er2O3 burnable poisonous fuel pellets. The experiments show that the main performance of the pellets, such as: integrity, density and grain size meet the requirements in the following sintering process: the density of green pellets should be among 55%~60%T.D., the temperature is 1700~1750℃, and sintering in hydrogen atmosphere for 2~3 h.-
