ABSTRACT:
Apparatus for limiting the effect of axial hydraulic flow force exerted on the fuel assemblies by the hydraulic pressure of a coolant in a water-cooled nuclear reactor comprises slit cylindrical elastic sleeves positioned within recesses in cylindrical housings carried by the fuel assemblies, the sleeves receiving centering pins connected to upper and lower core plates of the reactor and exerting frictional force thereon so as to control the axial movements of the fuel assemblies during transient variations in hydraulic flow force.
