Abstract: This paper delves into the study of the radiolytic gas bubbles formation in uranium salt solutions using the ImageJ software for the determination of parameters of interest of the gas bubbles. In this way the gas bubbles diameter, gas bubbles velocity and local gas volume fraction for three electron bean power levels, 6, 12 and 15 kW were determined. It was determined that the radiolytic gas bubbles average diameter varies between 200 and 300 μm, increasing with the increase in power. A similar behaviour was observed for the bubble velocity, which increases accordingly with the increase in power density. The study of the gas volume fraction indicated that although the radiolytic gas bubble size does not increase significantly with increasing power, the number of bubbles and gas produced increases appreciably. All of these results were consistent with those reported by other authors in the literature.
