Turbine-driven control rod drive
This patent describes a drive for moving a control rod along a longitudinal axis in a reactor core disposed in a pressure vessel containing a pressurized fluid. It comprises: a housing extending from the core; a spindle disposed within the housing and mounted thereto for translation; a turbine rotor operatively joined to the spindle within the housing for translating the spindle upon rotation of the rotor; means for selectively rotating the turbine rotor in first and second opposite directions; and coupling means joined to an end of the spindle for selectively gripping the control rod for translation movement with the spindle for inserting and withdrawing the control rod into and from the core, and for upgripping the control rod.
