ABSTRACT:
An anti-earthquake support device arranged between an element of large mass and a fixed support, comprising roller elements arranged between support parts forming roller tracks inclined with respect to the horizontal plane. The roller elements are cylindrical rollers (14,15,17) arranged horizontally in two superposed sets of rollers with perpendicular axes. The support parts (4,10 and 11) are entirely independent of one another and are arranged above one of the sets of roller for the first (4), between the two sets of rollers for the second (10) and beneath the second set of rollers for the third (11). The corresponding roller tracks (9, 20, 21 and 24) are formed on either the lower, or the lower and upper, or the upper surfaces of the three support parts (4, 10 and 11), respectively. The invention is used for the support of a fuel assembly rack for a nuclear reactor on the bottom of the storage pool of such reactor.
