Abstract
Device for guiding nuclear reactor control clusters consisting of several absorbing rods including guide casings, associated respectively with the various control clusters, and, inside each casing, horizontal plates (14) ensuring, in the upper part, discontinuous guidance at intermediate levels for the various elements of the control cluster. In the lower part of the casing, guidance of the rods arranged in pairs sharing one radius is achieved by combining horizontal plates (14) ensuring mechanical guidance of the rods with casings (22) which reduce the hydraulic effects to a minimum by calming the cooling fluid in the radial direction around the said absorbing rods. The invention applies to pressurized water nuclear reactors.
