Abstract
A nuclear reactor includes a plurality of mechanisms () that drive the contact members () that control the reactivity, of the core. Each mechanism includes a driving member () including a driving part () forming one out of a screw or a nut, a member () for applying a rotary torque of the rotor () to the driving member (), a driven member () translationally connected to one of the control members () and including the other out of screw and a nut; and a member () that is selectively mobile between a position of blocking the driving member () and a position of releasing the driving member (). In each drive mechanism (), the motor () is fully immersed in the primary coolant inside the vessel (); the rotor () has a central passage (), the member for applying the rotary torque () being situated in or near the central passage (); the driving member () includes a connecting part () engaged in the central passage () and collaborating with the member for applying the rotary torque (), the connecting part () being free to effect a translational movement inside the central passage () with respect to the rotor () when the or each blocking member () is in the releasing position.
