The present invention relates to a device providing anti-seismic support for an apparatus immersed in the bath of liquid alkali metal surrounding a fast neutron nuclear reactor, and abutting by a flange on a slab traversed by the apparatus and resistant to the load that it constitutes, wherein the flange for supporting the apparatus is connected to a sleeve for elastically taking up the horizontal displacements of its top part, independently of an inner envelope of the apparatus and on which a framework for supporting the apparatus whose bottom part is connected to the inner envelope, is fixed at a level determined as a function of the most dangerous earth tremor frequencies.
