Control rod drive
This patent describes a drive for moving a control rod along a longitudinal axis in a reactor vessel containing a pressurized fluid. It includes a pressure vessel fixedly joinable in flow communication with the reactor vessel; a spindle disposed solely within the pressure vessel; means for moving the control rod upon rotation of the spindle; a driven rotor fixedly joined to the spindle within the pressure vessel for rotating the spindle; and means spaced from the driven rotor for selectively rotating the driven rotor in first and second opposite directions without breaching the pressure vessel between the driven rotor and the retaining means; a center of area and axes of symmetry passing through the center of area.
