After several years of minimal operation and no maintenance, Denison Mines elected to upgrade and restart the White Mesa facility. Precision Systems Engineering was contracted to assist with three main components of the upgrade: the modification of the existing uranium mill, the mitigation of vanadium dust/fumes, and the design of an alternative feedstock processing system.
