1. A device for confining the melt of a nuclear reactor core, comprising:a melt trap body configured to be mounted below a bottom of a reactor vessel, the melt trap comprising a cooled multilayered housing;a filler for diluting melt, the filler being arranged in the multilayered housing;an upper melt trap support; anda lower melt trap support comprising a horizontal embedded plate mounted under the multilayered housing and configured to be mounted in concrete of a reactor shaft;wherein the embedded plate comprises lower radial supports and the multilayered housing comprises upper radial supports resting on the lower radial supports of the embedded plate;wherein the lower radial supports and the upper radial supports are connected by means of fasteners and comprise oval holes, and the fasteners have openings in the form of hyperbolic surfaces; andwherein the upper melt trap support comprises a plurality of turnbuckles mounted in pairs on an upper part of the multilayered housing such that, from a top view of the melt trap body, each lower radial support extends in projection equidistantly from file attachment points of corresponding paired turnbuckles of the plurality of turnbuckles, the corresponding paired turnbuckles mounted tangentially to the melt trap body and configured to connect the melt trap body to a vertical wall of the reactor shaft. 2. The device of claim 1, the embedded plate being a sectional embedded plate. 3. The device of claim 1, the embedded plate being a solid embedded plate. 4. The device of claim 1, the embedded plate being an embedded plate made of separate pieces.
