Abstract
The present invention relates to an anti-fly-off device for the fuel element of a nuclear reactor. This device, which is applicable to a nuclear reactor, comprises a plurality of sheathed fuel elements kept parallel to one another by a system of spacing grids and a stucture, independent of the fuel elements and formed by two parallel plates, namely an upper plate and a lower plate, between which extend brace rods regularly distributed among the system of fuel elements, whereby at least certain of these brace rods are surrounded by grid sleeves. A casing introduced into the grid sleeves of the lower grid around the brace rods and fixed by its lower end to the lower plate has at its upper end an outer shoulder which, with an appropriate clearance, blocks the upward displacement of the grid sleeve.
