Abstract
The behavior of a melt of a UO2–ZrO2–SiO2–Fe3O4–CaO–Al2O3 system that is formed in the case of the dilution of corium (a melt of a UO2–ZrO2–Zr system) with sacrificial materials (a mixture of aluminum and iron oxides with Portland cement) has been studied. It has been found that, as a result of the evaporation of oxides, spherical aerosol particles are formed, the sizes of which have a trimodal distribution (1, 5, and 11 μm) and the composition of which depends on the nature of the atmosphere over the melt: 90.8UO2 · 5.2SiO2 · 4.0Fe3O4 in the atmosphere of nitrogen and 68.9U3O8 · 6Al2O3 · 2.5Fe3O4 · 22.5Na2O in air.
