特徴とする水圧駆動制御棒駆動装置。 The control rod cluster is attached to the lid of the reactor vessel and drives the control rod cluster with respect to the reactor core in the reactor vessel between a fully inserted state and a fully withdrawn state, and is attached to the lid. In a hydraulic drive control rod drive device comprising a cylindrical pressure housing and a drive shaft connected at a lower end to an upper end of the control rod cluster within the pressure housing, an end plug at the upper end of the pressure housing has an opening/closing mechanism. A free fluid passage is provided, a rotating sleeve having a guide device on its outer surface is fitted in the upper part of the drive shaft so as to be rotatable with respect to the drive shaft, and an inner surface of the pressure housing is provided with a rotating sleeve having a guide device on its outer surface. A support protrusion that can support the drive shaft via a guide device is in a lower position, a rotation guide protrusion that rotates the rotary sleeve by a predetermined angle via the guide device is in an upper position,
A hydraulic drive control rod drive device, characterized in that the rotation guide projections selectively rotationally guide the guide device between an engagement position and a non-engagement position with respect to the support projections.
