The CLADS-MADE-05 is the next test in the series of large-scale tests performed in JAEA with a purpose of understanding of mock-up assembly degradation and melt propagation behaviour accompanied by Cs and B containing aerosol release. A possibility of Cs and B aerosols interactions in RPV and formation of a new Cs bearing contaminating phase has been shown. This paper analyses the data on aerosol behaviour of Cs and B bearing aerosols when they interact in the gas line, and concentrates on the phenomenon of possible reactions on the liquid-liquid and liquid-gas interface when aerosols are interacting during the large-scale bundle degradation test.
