SEPARATION OF PLUTONIUM AND AMERICIUM BY LOW-TEMPERATURE FLUORINATION

[摘要] We have demonstrated separation of Pu and in-grown Am using the gaseous reagent dioxygen difluoride. Aged PuF4 was fluorinated at room temperature to generate PuF6 gas, which was trapped separately and reduced to PuF4. The reaction product contained very little Am. Unreacted solid had elevated concentrations of Am that were consistent with a material balance. Use of a gaseous reagent and product enabled remote handling during reaction and purification. This result demonstrated a simple and minimal waste alternative that may have application to a number of actinide purification problems.
