“…The U-10 wt.% Zr fuel slugs with various levels of RE content (0, 3, 5, and 7 wt.%) were fabricated by modified injection casting and the RE alloy consisted of 53% Nd, 25% Ce, 16% Pr, and 6% La based on the weight ratio [7,8]. The graphite crucible was coated with yttrium oxide by applying a plasma-spray coating to prevent interaction behavior between the molten uranium alloy and the graphite crucible [13][14][15].…”

“…The injection casting is one of the processes that fulfills these needs and it has strong advantages in terms of fabricating small diameter castings with a high L/D ratio and a randomly oriented grain structure, enabling precision castings [2,5]. The U-Zr metallic fuel slugs containing rare-earth elements for a SFR were fabricated using a modified injection casting method [6][7][8]. Unlike the conventional injection casting that operates under the atmospheric pressure, the modified injec-tion casting method prevents the evaporation of volatile elements in pressurized Ar atmosphere, during melting of metallic fuel [6].…”

“…In previous work, the metallic fuel slugs with various RE contents were fabricated, in order to investigate the RE deficiencies in the fuel slugs, the distribution of component in the fuel slugs and melt-residue was discussed [5][6][7][8]. In this study, the metallic U-10wt.%Zr fuel slugs containing various levels of RE content (0, 3, 5, and 7 wt.%) were fabricated by a modified injection casting method.…”
