OSTI ID:4340037
A combined energency switch-off and control rod drive for a control rod of a gas-cooled nuclear reactor includes an electrical notor coupled through a clutch to a cable winch on which is wound a cable connected to the control rod for lowering the rod into the reactor core. One brake of the eddy current type is provided for controlled braking of the cable and a locking brake is provided for purposes of emergency. This locking brake is actuated in accordance with the response of a cable monitoring device whlch is arranged to detect both a relief of the cable as well as an overload. (Official Gazette)
