ABSTRACT:
The invention relates to a method for producing an assembly, as well as to an assembly produced by this method.
The foot of the assembly is butt welded to the hexagonal tube prior to the introduction of the bundle of rods into the latter. This introduction takes place in the vertical direction using a jack which passes through the foot of the assembly. The upper neutron protection is then fixed by pressing the tube into recesses. Finally, the vacuum producing system and the plug are fitted in the foot.
Application to assemblies for fast neutron nuclear reactors.
