Abstract

PURPOSE: To provide a control rod driving system by locating the snapper element at the bottom of the device to absorb shock during the scram by enabling the maintenance of the system to facilitate and the full snapper effect to obtain with small diameter mechanism.
CONSTITUTION: For the control rod driving system where the driving shaft 2 joined with the control rod at the top not shown in the drawing is arranged movable in the axial direction, the tip cylinder 27 joured with the insertion tube not shown in the drawing at the top end, the reduced diameter step element 28 is provided for the bottom section joining the bottom end thereof with the pressure tube 5 with the same diameter. The positioning flange 29 is provided for the driving shaft 2 within the cylinder 27. Further, the feeding mechanism 11 including the rotation nut around the bottom small diameter section of the cyliner 27. Thereby, the snapper element is provided for the bottom end plug 6' mounted at the bottom end of the system. This comprises the rod type piston 30 secured protrusively at the bottom end of the plunger assembly 4 and the internal tube 31 within the end plug 6'.
