Year: 2015

The sol-gel method, which is among the methods used for the production of ThO2-UO2 mixed oxide fuel pellets, allows a high degree of micro-homogeneity of uranium and thorium in the solution stage. The present study seeks to develop an alternative method in order to produce mixed thorium-uranium dioxide fuel pellets, prepared by internal gelation technique of sol-gel process. The study also aims to investigate shrinkage behavior and rst-stage sintering kinetics of pellets compacted in the Ar-5%H2
