Enhanced dissolution of PuO2 in nitric acid using uranium(IV)
Abstract
The dissolution of PuO2 is a fundamental problem in nuclear technology. In this work the effect of the U4+ ion on the rate of dissolution of PuO2(s) in HNO3 was tested by experimental measurements. The U4+ ion greatly increases the rate of dissolution crystalline of PuO2 powder in 5 mol dm–3 HNO3 at 90 °C.
