Abstract
A series of rod-shaped elements containing nuclear fuel are individually mounted between two parallel, spaced assembly plates or grids with a bundle of fuel elements for forming the outer row of fuel elements of the bundle. The elements are mounted asymmetrically by locating a rod which carries parts of reduced cross section projecting axially at the ends extending coaxially w.r.t. the fuel element or rod between two end assembly plates, so that one part of each projecting part extends radially outwards beyond the edge of the end assembly plate and the regions of the projecting parts covered by the end assembly plates are welded to such plates to fix the elements between the assembly plates.
