摘要
A control rod drive (2) comprises a housing (8) in which a control rod support element (40) travels between a base position and a final position. A flow path (42) is provided for a pressurized fluid and passes through a throttle bushing (30). The path has a free flow cross-section which varies depending on the actual position of the control rod support element. ??An Independent claim is also included for moving a control rod into a reactor core of a boiling water reactor. The free flow cross-section increases from the base position to the final position. The control rod support element has a changing outer diameter. The control rod support element is formed as a hollow plunger having a bypass opening in one wall.
