FUEL ASSEMBLY STABILIZATION DEVICE

A fuel assembly stabilization device, comprising a positioning plate (10) corresponding to an inner cavity of a fuel assembly transport container, a sleeve (20) for being sleeved outside a central barrel of a control rod assembly, and a compression sleeve (30) for detachably fitting to an upper end of the central barrel. The positioning plate (10) is provided with a central through-hole (100), the sleeve (20) is vertically connected onto the positioning plate (10) in conjunction with the central through-hole (100). The compression sleeve (30) is provided inside the sleeve (20) and may be moved back and forth along the axial direction of the sleeve (20). The fuel assembly stabilization device is used for the fuel assembly transport container, to axially fix the control rod assembly on the fuel assembly therein, and thus also axially fix the entire fuel assembly, which may effectively reduce the damage to the assembly from an external impact.
