ELECTROCHEMICAL STUDIES OF URANIUM METAL CORROSION MECHANISM AND KINETICS IN WATER
During long-term underwater storage of low burn-up uranium metal fuel, a corrosion product sludge forms containing uranium metal grains1, uranium dioxide1,2, uranates1 and, in some cases, uranium peroxide1,3. Literature data on the corrosion of non-irradiated uranium metal and its alloys2,4 do not allow unequivocal prediction of the paragenesis of irradiated uranium in water. The goal of the present work conducted under the program «CORROSION OF IRRADIATED URANIUM ALLOYS FUEL IN WATER» is to study the corrosion of uranium and uranium alloys and the paragenesis of the corrosion products during long-term underwater storage of uranium alloy fuel irradiated at the Hanford Site. The elucidation of the physico-chemical nature of the corrosion of irradiated uranium alloys in comparison with non-irradiated uranium metal and its alloys is one of the most important aspects of this work. Electrochemical methods are being used to study uranium metal corrosion mechanism and kinetics. The present part of work aims to examine and revise, where appropriate, the understanding of uranium metal corrosion mechanism and kinetics in water.
