Density decrease of oxidatively sintered UO2–5wt%CeO2 pellets during resintering in H2 atmosphere
Source abstract
Abstract
Abstract Pellets admixed with zinc stearate showed density decrease of 3%T.D. during resintering in H 2 atmosphere, but density change was below 0.4%T.D. in the pellets admixed with Acrawax and stearic acid when all the powder compacts were sintered in CO 2 atmosphere. Experiments revealed that the density of the pellets doped with zinc compounds and sintered in CO 2 also displayed a density decrease of 3%T.D. after resintering. Therefore, it was considered that the major cause of the large swelling of the pellets sintered in CO 2 atmosphere after resintering was Zn residues.
