A study of the decontamination of thorium-uranium alloy by the consumable-electrode arc-melting process was carried out. Cesium and strontium removals of up to 75% were obtained, whereas cerium and rare earth removals were less than 20%. Metal loss increases with increasing power to the arc. The method is not suitable for a decontamination process but could be utilized as a step in a low-decontamination, reprocessing method.
