| Abstract Scope |
Nuclear power is promising; however, feedstock production requires greater waste mitigation. The Hydride-Dehydride (HDH) process is one method for producing uranium alloy feedstock powder with a tunable particle size. This HDH process is favorable as it enables the oversized material to be recycled with additional rounds of HDH, thereby increasing yield. However, the undersized particles cannot be easily reprocessed in this manner, rendering them waste. The major generator of the undersized powder is the milling step. We present our work where we developed a method of targeted low impact milling of U-6 wt% Nb which produces a comparable mass fraction of target particle size with reduced waste production. The processed powders were further investigated with characterization of crystal structure, magnetization, and microscopy.
This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
