Abstract
A device for the centering and fixation of a cluster guide flange and of a core plate of a nuclear reactor, extending parallel to one another in horizontal planes with a predetermined spacing. The device includes at least two axial guiding spindles of flange with respect to the core plate, diametrically opposite and rigidly connected to the plate or to the flange in order to engage into a housing in register formed in the flange or in the plate, respectively, and an assembly of self-locking shoes, adapted for sliding with a clearance within bores formed in the flange in order to be pressed on the plate surface, these shoes being each associated with a position control mechanism, carried by the flange and exerting on the shoes a force having a transverse component so as to cause, by reaction, immobilization of the flange with respect to the plate.
