Abstract

A nuclear reactor control rod is driven by an electric motor coupled through reduction gears to a bar. Profiled grips are mechanically connected to the bar. Movement of the grips is controlled by a coaxial rotary tube. The engagement of the drive system with the control rod is signalled by a device which interacts with an inductive rod position transducer. The device includes a spring-loaded sensing rod. The system may be used for controlling power, excess reactivity and emergency shutdown in an alkali metal cooled fast reactor. The drive system takes up less space than known arrangements, is reliable in operation, can reduce fuel recharging time.
