Metallic fuel is a candidate for use in the sodium-cooled fast reactors (SFR) that are being considered as a transmutation system for the long-lived transuranic elements of spent nuclear fuels. U-Zr-RE (RE: Nd, Ce, Pr, and La) fuel slugs were fabricated by injection casting and characterized to develop an optimal fabrication process for metallic fuels for SFR. The morphology of U-Zr alloy exhibited a lamellar structure with Zr-rich inclusions. In U-Zr-RE alloys, the inclusions were dispersed throughout the fuel slugs. The inclusions could be categorized into two groups, namely, with Zr-rich inclusions and with RE-rich inclusions. The fraction of the inclusions does not significantly change in the U-Zr-RE alloys when the RE content is higher than 5 wt.%. The reaction between the melt and crucible was found to be significant in the fabrication of U-Zr-RE fuel slugs when compared to that observed in the injection casing of U-Zr alloys.
