CONTROL ROD FOR A NUCLEAR REACTOR
A control rod for a nuclear reactor, which slides in a tube positioned in the reactor and being open at its innermost extremity, is moved in the axial direction by a mechanism. This movement of the rod is signalled to the control unit for the control rod drive by the rotation of a shaft mounted in the axis of the said tube. This shaft has a threaded portion on which a screw nut moves axially because of the rotation. The screw nut supports a magnetically or electrically conducting cylinder sliding in a coil, the inductivity of which is defined by the axial position of said cylinder. The control unit outside the reactor comprises a similar equipment, the shaft rotation of which is steered in accordance with the desired control rod position, while the inductances of the coils of the two equipment sets define an inductance dlfference which generates an appropriate control signal for the control rod movement.
