Securing device for a control rod in a nuclear plant

摘要

A securing device for a control rod in a nuclear plant contains a control rod drive and a drive housing, which encloses the control rod drive and which is configured to be fed through a reactor pressure wall. The aim of the securing device is to prevent, in the most reliable manner possible, the control rod from being extended in an uncontrolled manner. Furthermore, the securing device should be as inexpensive as possible and should pose the slightest obstacle possible to installation work. For this purpose, the drive housing has at least one coupling element for forming a force-locked and/or form-fit connection of the drive housing to the reactor pressure wall.
