Aerosols over melts of a corium–sacrificial materials system
The behavior of a melt of a UO 2 –ZrO 2 –SiO 2 –Fe 3 O 4 –CaO–Al 2 O 3 system that is formed in the case of the dilution of corium (a melt of a UO 2 –ZrO 2 –Zr system) with sacrificial materials (a mixture of aluminum and iron oxides with Portland cement) has been studied. It has been found that, as...

–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: 90.8UO
