The evaporation of fission products from thorium-uranium alloy by melting in an electric arc has been investigated. Effective removal of cesium and strontium was observed while the rare earths were partially removed and the refractory metals remained in the alloy. Uranium and protactinium are vaporized when heated at high temperatures and for long periods. There is an indication that a consumable melting process is reasonably suitable as a high temperature method for decontaminating thorium fuels.
