Abstract
Actinide nitrides, in particular UN, are being considered as fuel types for advanced reactor systems. Here, we demonstrate a low-temperature synthesis route on uranium that could be developed into a commercial fabrication process for UN and mixed actinide nitride fuels. UN was successfully synthesized from UO 2 by first reacting with NH 4HF 2 in a ball mill at 20 °C to form tetravalent ammonium uranium fluorides. Then, reaction with an ammonia atmosphere at 800 °C oxidized tetravalent uranium fluorides to hexavalent UN 2. The final product, UN, was obtained by decomposing UN 2 at 1100 °C under argon to produce UN through an intermediate phase of U 2N 3.
