Water boiling on the corium melt surface under VVER severe accident conditions

Experimental results are presented on the interaction of coriurn melt with water supplied on its surface. The tests were conducted in the ʹRasplav-2ʹ experimental facility. Corium melt was generated by induction melting in the cold crucible. The following data were obtained: heat transfer at boiling water-melt surface interaction, gas and aerosol release, post-interaction solidified corium structure. The corium melt charge had the following composition, mass%: 60% UO(2+x)-16% Zr0(2)-15% Fe(2)O(3)-6% Cr(2)O(3)-3% Ni(2)O(3). The melt surface temperature ranged within 1920-1970 K.
