A model for solid bubbles formation in melt–coolant interaction

A comparative analysis of shielding of thermal radiation of fires using mist curtains containing droplets of pure water or sea water

“…The crust is destroyed when the tensile stress in the crust exceeds the ultimate tensile stress in a polycrystalline sea salt. It should be recalled that similar theoretical estimates have been performed in papers[33,35,36] as applied to solidified particles of core melt in the case of a hypothetic severe accident of nuclear reactor. For simplicity, we neglect the time of solid crust formation in the present paper.…”

“…When fractured and viewed under the microscope, the dried particle proved to be a very thin shell composed of large crystals". It is also interesting to remind the formation of hollow bubble-like solid particles in nuclear melt-coolant interaction [33].…”

Steam explosion in nuclear reactors: Droplets of molten steel vs core melt droplets

“…The alternative theoretical model of this process developed in paper [76] was motivated by the laboratory observations of [77,78] where numerous small particles of radius a < 1 mm with thin wall of thickness d < 0:1 mm and single surface orifices were found in the debris bed after the experiment. Some of these ''solid bubbles" were destroyed and the character of the damage looks like a crush under the action of high external pressure at the cooling stage of the process.…”
