Abstract
In a nuclear reactor fuel element, particularly for a liquid metal-cooled, fast neutron reactor, the plug for maintaining the column of fuel pastilles in the interior of the fuel element sheath, comprises an axially compressible spring co-operating at one end with teh pastilles and at the other end with a plug-type piece, having an insert bearing for the spring,a conical body surrounded by an elastic ring and a head at the end opposite that of the spring. Construction combines the advantages of spring pressure on the assembly fuel tablets i.e. facility for expansion, with the simplified procedure for welding-in the closure plug of the type of element using a split ring fuel tablet retainer.
