1. A melt localization device, comprising:a double-walled cooled case, a bottom of the double-walled cooled case being recessed to a center of the bottom with a slope, and filled with filler;a guiding element for organizing movement of a melt;a passive system for supplying water to the surface of the melt,wherein the filler comprises several upper cassettes and a lower cassette, each cassette of the upper cassettes and the lower cassette containing one vertical central storage channel and several vertical peripheral storage channels of equal diameters, wherein the diameter of the vertical central storage channel exceeds the equal diameters of the vertical peripheral storage channels,wherein for each cassette of the upper cassettes and the lower cassette, the cassette further comprises horizontal radial distribution channels connecting the vertical peripheral storage channels of the cassette to the vertical central storage channel of the cassette, and wherein for each upper cassette of the upper cassettes, the upper cassette comprises horizontal azimuth distribution channels connecting the vertical peripheral storage channels of the upper cassette with each other,wherein the horizontal radial distribution channels of the lower cassette are made with a slope, the angle of which coincides with the slope of the bottom of the melt trap body,wherein the horizontal radial distribution channels and the horizontal azimuth distribution channels have equal diameters,wherein the upper cassettes and the lower cassette contain ceramic plates having microchannels separated by horizontal slot channels and vertical slot channels, and the upper cassettes and the lower cassette are mounted on top of one another in such a way that contours of the vertical central storage channel of the upper cassettes and the lower cassette coincide with each other to provide a combined vertical central storage channel and contours of the vertical peripheral storage channels of the upper cassettes and the lower cassette coincide with each other to provide a plurality of combined vertical peripheral storage channels. 2. The melt localization device according to claim 1, characterized in that the vertical peripheral storage channels of the upper and lower cassettes are located on the same axial axis with a corresponding radial rib of the cooled case. 3. The melt localization device according to claim 1, characterized in that a depth of the combined vertical central storage channel formed by the upper cassettes and the lower cassette exceeds a depth of each of the plurality of combined vertical peripheral storage channels. 4. The melt localization device according to claim 1, characterized in that a damper is installed in the combined vertical central storage channel, and comprises a central shell, power ribs connected to the central shell, inclined plates located between the power ribs, and clamps that secure the damper to the cooled case.
