Keywords:Simplified MOX pellet fabrication method, additive-free dry granulation technology

JAEA has researched and developed a simplified MOX pellet fabrication method. In this process, the flowability of MOX powder is improved by a tumbling granulation method using water as a binder. However, in this granulation method, improvement of the production capacity under criticality control for wet nuclear material is an issue. In recent years, an additive-free dry granulation technology has proposed as a novel granulation method for producing tritium breeding Li2O spheres for nuclear fusion reactor. In this study, to confirm the applicability of this method to the MOX fuel fabrication process, the results of the confirmation test of granulation characteristics using a simulated material are reported.
