Abstract

Metal fuel is a promising candidate for the pyro-processed nuclear fuel, but the problem of loss of nuclear material due to the high reactivity of metal fuel and melting crucible in the metal fuel casting process must be solved for loss control and waste reduction. In this study, fabrication test was conducted to develop a new material NdYO3 as a new crucible material to improve the degree of anti-reactivity. The NdYO3 compact was manufactured by the CIP (Cold isostatic pressing) method with changing fraction of Nd2O3 and Y2O3 powders. Sintering process was performed at 1550°C for 10 hours. The systematic trends of XRD patterns shows that phase transformations form cubic structure to monoclinic structures occurred with the addition of Y2O3. The rate of pore were discussed with change of fraction of Nd2O3 and Y2O3.

Abstract

LaYO3 which has phase stability at high temperature is introduced as a promising candidate for reaction-preventing crucible materials with Uranium-Zirconium (U-Zr) melt containing rare-earth elements (RE). RE is composed of rare-earth elements such as Nd, Ce, Pr and La. The LaYO3 material was synthesized by a solid-state reaction method at elevated temperature according to a pseudo-phase diagram of LaYO3 and Y2O3. Green compacts blended with La2O3 and Y2O3 powder were made by the Cold Isostatic Pressing (CIP) method, with La2O3 and Y2O3 powders varying with molar ratios from 1.0 to 1:2. LaYO3 synthetics were fabricated at sintering temperatures ranging from 1450°C to 1600°C. LaYO3 pellets sintered at below 1550°C showed a highly dense orthorhombic phase with a perovskite structure, resulting in an enhancing reaction-resistant effect with RE.

Abstract

An alternative fabrication method for metallic fuel in Gen-IV reactor was introduced with vibration packing of nuclear fuel particles to facilitate remote fabrication in a hot cell and reduce the generation of long-lived radioactive wastes. Vibration packing experiments on metallic particulate fuel using a surrogate 316L stainless steel powder were done to investigate the packing density and the uniformity of the simulated fuel according to the filling method and the vibration condition. Metallic particulate fuel filled with a pre-mixed power over all particles had the highest packing fraction and the most uniform distribution among the filling methods. The vibration packing method showed that it could fabricate the metallic particulate fuel having uniform distribution of spherical fuel particles through the adjustment of the filling method of the metallic powder and the vibration condition of the metallic particulate fuel.
