Abstract
The apparatus comprises a body (13) housed in the bore (2, 5) of the assembly head (1) and a flow rate constrictor (12) housed in the sodium passage channel (4) in the assembly head (1). The body (13) comprises axial locking fingers (30) in the assembly head, which can be maneuvered by a slide block (20) actuated by an assembly manipulating device (9). The flow rate of coolant liquid circulating in the assembly may be easily adapted to the operating conditions of the assembly.
