Kinetics of Separations of Volatile Fluorides from Used Fuel Using NF3

Abstract

The study of the fluorination of UO2 with various fluorinating agents using thermogravimetric analysis (TGA) is well documented.1-5 Additional research has examined the fluorination of other metals and metal oxides6-7. Seeing the possible benefit of using analogous fluorination technologies to affect separations in used nuclear fuel, we have expanded the existing research to an investigation of the reaction of NF3 with UO2 and NpO2. The conversion fractions gathered from experimental results have been compared with those predicted by existing models for various rate-limiting phenomena.8
