Summary:PURPOSE:To prevent the control rod from being lifted and to effectively prevent reactor water from leaking by coupling or separating the control rod and a coupling member while the control rod is sit in a control rod guide pipe at all times. CONSTITUTION:When a CRD handling device main body 45 supports the lower part of a CRD body 41, an elastic support member 52 supports a hollow piston assembly part 51 and a ball screw assembly part 50, but when only the hollow piston assembly part 51 and ball screw assembly part 50 are supported, they are supported rigidly and when the load of the control rod 11 is placed, a support spring 48 deforms elastically by receiving a large load to support them elastically. When the load of the control rod 11 is placed on an elastic support mechanism 52, the support spring 48 deforms and the control rod 11 is not lifted from the control rod guide pipe 12, so the reactor water in a nuclear reactor pressure container 12 is securely and effectively prevented from leaking.
