Abstract
Abstract In a fuel assembly for insertion from above into a nuclear reactor core a fuel rod bundle is arranged as a freely moveable loose insert in a weight carrying square sheathing tube, which has at its upper end connection members such as two diametrically opposed lifting lugs permitting a grab member in a lifting device to grab the sheathing tube for lifting the entire fuel assembly. The upper part of the sheathing tube is formed as it springs supporting the fuel assembly laterally against an upper core grid and supporting the fuel rod bundle laterally against the sheathing tube wall.
