Abstract

PURPOSE:To increase the speed of inserting a cylindrical body, which is freely movable in a perpendicular direction at a prescribed amplitude, onto a control rod assembly and to shorten the time for control by providing the above- mentioned cylindrical body to the outside circumferential part of a base plate and providing a buffer device which controls the rapid vertical movement of the cylindrical body between the base plate and the cylindrical body. CONSTITUTION:The cylindrical body 10 which is freely movable at the prescribed amplitude is provided to the outside circumferential part of the base plate 2. Vanes 3 are fixed to the outside circumference of the cylindrical body 10. The buffer device 11 such as spring which controls the rapid vertical movement of the cylindrical body 10 is provided between the base plate 2 and the cylindrical body 10. The force which acts on control rods 5 is transmitted through the vanes 3 to the cylindrical body 10 even if the abnormal force acts on the control rods 5 when the control rods 5 receive resistance in guide pipes by a certain cause. The cylindrical body 10 is gently moved relative to the base plate 2 by the buffer effect of the device 11. The speed of inserting the cylindrical body to the fuel rod 5 assembly is thereby increased and the time for control is shortened.
