Development of NdYO3 Powder Fabrication as a Reaction Preventing Raw Material for Metal Fuel Casting

Metal fuel is a promising candidate for fast reactor, but the problem of loss of nuclear material due to the high reactivity of the metal fuel and the melting crucible in the fuel casting process must be solved for loss control and waste reduction. To this end, it is necessary to develop a new coating material that can minimize high reactivity in order to develop new material casting parts capable of reducing reaction loss. In this study, research was conducted to develop a new material to improve the degree of anti-reactivity of the crucible. Research was conducted to develop a new material from Nd-Y-oxide based materials, which has shown good anti-reactivity previously. YAG (Y3Al5O12), YNdLa, YZrNd, YNdCe oxide materials were selected as a candidate material. This study identifies NdYO3-based materials as the most promising candidates for high-temperature applications due to their superior reaction resistance.
