Laboratory Simulation of Uranium Metal Corrosion in Different Soil Moisture Regimes

Abstract

A novel laboratory simulation system has been developed for the study of the corrosion of uranium metal in soils. Corrosion and transportation of depleted uranium (DU) as the metal undergoes weathering as a buried material within the soil environment. The corrosion of uranium metal in soil was not well understood due to the gas-liquid-solid phase of the soil. This study presents a novel method to investigate the change of uranium species during the process of process of oxidation of metallic uranium in these environments. Compared with other techniques used for the study of environmental corrosion of metals in soils, this method has the advantage of low secondary uranium pollution, no energy consumption, and ease of operation. The simulation system has been used for the following studies: Simultaneously simulate the corrosion of uranium metal in different soil moisture regimes, Study the influence of biogeochemical factors on the corrosion of uranium metal, Investigate the change of uranium species during oxidation.
