Development of Casting Techniques for ẟ-phase Uranium-Zirconium Alloys, Lightbridge Corp

The casting, processing, and shipping of HALEU alloys, like those being developed by Lightbridge, require the ability to experiment with higher temperatures in a facility that can perform these functions. The goal of this project was to identify an appropriate casting method (i.e., crucible and coating combination) that results in an acceptable impurity concentration in the as-cast ingot.
