Abstract [en]

-The problems regarding the design of a new class of materials, namely, sacrificial materials for usein devices intended for localization of a core melt of the nuclear reactor, are considered. Criteria are proposedfor the proper choice of the chemical composition of a sacrificial material, as well as of the composition andmicrostructure of its constituents. The possible alternatives are outlined and analyzed. The results of designinga variant of the composition of sacrificial materials are presented. The experimental data on the interaction ofan oxide sacrificial material with simulators of the metal and oxide phases of the core melt are discussed. A newtype of combustion of materials, namely, the liquid-phase combustion, is revealed. It is demonstrated that thematerial designed can be used in systems intended for localization of a core melt of the nuclear reactor.
