Abstract
The invention concerns a process for the final assembly of a nuclear reactor vessel comprising two sub-assemblies which are brought together and welded along mating surfaces. At least three female centering stubs, each associated with a seat recessed relative to the outer surface of the stub, are provided on the mating surface of one of the sub-assemblies, and at least three male centering stubs, corresponding to the seats of the female stubs, are provided on the mating surface of the other sub-assembly, the positions of the stubs being registered relative to elements for positioning internal fitments of the vessel. The two sub-assemblies are brought together to engage the male stubs in the female stub seats and to bring projecting annular ridges on the mating surfaces into contact. A key is inserted into a socket defined by one of the pairs of stubs and the stubs are then joined to each other by point-welds. An annular space defined between the mating surfaces of the sub-assemblies and delimited by a wall provided by the contacting ridges is then partially filled with filler metal. The centering stubs, wall and part of the deposited metal are then removed before welding is completed by filling the gap between the mating surfaces with filler metal. The invention is particularly applicable to the assembly of vessels for pressurized-water nuclear reactors comprising upper and lower sub-assemblies, which are assembled in a horizontal position.
