Abstract
A device for guiding control rods of the absorber-pin cluster type and placed above the reactor core comprises a rigid top plate applied against the reactor vessel and provided with openings joined to long vertical tubes in which the control rod assembly is slidably mounted, an intermediate plate below coolant outlets for the sliding displacement of each absorber pin through corresponding apertures in said plate, and short connecting tubes which preferably provide a mechanical connection between the intermediate plate and a bottom plate and serve to guide the absorber pins, or alternatively short connecting tubes which guide the absorber pins and support members rigidly connected between the plates.
