Description

A new method of recycling oversized DC-UO2 powder in UO2 fuel pellet fabrication process is investigated. The oversized DC-UO2 powder is annealed below the equilibrium oxygen potential of U3O8 phase in order to increase the density and size of the oversized DC-UO2 powder. The annealed particle is oxidized to U3O8 powder in air atmosphere, and then recycled by mixing with UO2 powder in conventional UO2 pellet fabrication process. This process provides green pellets with high strength and sound sintered pellets without ring-like pores
