This patent describes the unrodded refueling of a nuclear reactor having fuel assemblies and upper internals with apparatus including a lifting rig and a lift plate. The upper internals of the reactor are secured to the lifting rig. A method is given of reinserting in the fuel assemblies of the reactor the rods which penetrate into the fuel assemblies, such as control rods and/or coolant-displacement rods. The penetrating rods are connected to drive rods, the drive rods and penetrating rods being suspended from the lift plate, the lift plate and the drive rods and penetrating rods suspended therefrom being supported on a removable support in an upper position on the lifting rig.
