ABSTRACT:
The apparatus is for dismounting nuclear fuel assemblies comprising a skeleton having an upper end piece, a lower end piece, guide tubes connecting the end pieces and fuel rods maintained by grids between the end pieces. The apparatus comprises a cell displaceable vertically in a water tank and provided, at its upper part, with a base plate having an opening for passage of one said fuel assembly and provided with means for gripping an upper part of the bundle of fuel rods. A centering unit is operable by a handling tool and is arranged for gripping the upper end piece of a fuel assembly. The guide tubes may be disconnected from the upper end piece while the bundle of fuel rods is retained in the cell.
