Abstract
The guiding device comprises a body, the size of which corresponds to that of a fuel assembly, intended to rest on the lower core plate (20), equipped with holding means intended to be grasped by an assembly-handling machine, extended downwards by means (18) for positioning it on the lower core plate at an assembly location adjacent to the one intended to receive the assembly to be guided, and two wings (30) carried by the bottom part of the body, forming an angle of 90.degree. in a horizontal plane, each one having an inclined guide face (32) ending at the bottom above the location intended to receive the assembly when the device is in place. Each wing (30) can be retracted, starting from a deployed state, towards a position in which it is withdrawn within the horizontal size of the body.
