Results of study of the interaction products of reactor core meltdown with coolant and concrete

In the paper the study of products of interaction of corium with concrete (MCCI) has been carried out. The examination was stimulated in the experiment at the Vulkan stand. In the 6 experiments from 10 ones the interaction products were obtained in the form of fine particles that layer has formed in the concrete catcher under the corium ingot. Formation of the fragmentized products of mCi is caused mainly by the energy, stored in the meltdown before it water irrigation. Results of study of MCCI stark products and degraded concrete from the view of point the MCCI fragmentized products for clarification of the reasons of distinction in experimental results of different researches are generalized
