摘要： An insertion device for a bottom-entry control rod of a nuclear reactor comprises a mechanical spindle-nut drive and a hydraulic drive for rapid run-in of the control rod; in normal operation in the spindle rotates with its threaded portion in a non-rotating threaded nut, while in emergency rod insertion a hollow piston, which surrounds both the threaded spindle and also the nut and normally rests on the top of the nut, is hydraulically driven upwards to run the control rod into the reactor core; the hollow piston is permanently connected to the control rod by a coupling. A guide tube surrounds the spindle, the nut and the hollow piston and has a seal at its top end, through which the piston passes. The bottom end of the hollow piston has a non-return ratchet device, which is normally non-effective during mechanical operation but comes into action when hydraulic operation is used and prevents the piston from falling back again after it has been driven upwards to drive the control rod into the core. The seal between the upper end of the guide tube and the hollow piston is constituted as a labyrinth seal consisting of a number of annular grooves on the inner, cylindrical face of the guide tube; contactless movement between this cylindrical face and the outer face of the hollow piston is ensured by a number of guide rollers each mounted on a horizontal shaft and housed in a recess inside the cylindrical surface of the guide tube and bearing against the outer face of the hollow piston. Pref. these guide rollers are of a hard metal. The rolling contact of the guide rollers is used as a substitute for the more commonly used sealing rings and graphite sealing bearing. The new arrangement is much more reliable, less subject to wear and unlikely to adversely affect the operation of the control rod.

摘要： An insertion device for a bottom-entry control rod of a nuclear reactor comprises a mechanical spindle-nut drive and a hydraulic drive for rapid run-in of the control rod; in normal operation the spindle rotates with its threaded portion in a non-rotating thread nut, while in emergency rod insertion a hollow piston, which surrounds both the threaded spindle and also the nut and normally rests on the top of the nut, is hydraulically driven upwards to run the control rod into the reactor core; the hollow piston is permanently connected to the control rod by a coupling. A guide tube surrounds the spindle, the nut and the hollow piston and has a seal at its top end, through which the piston passes. The bottom end of the hollow piston has a non-return ratchet device, which is normally non-effective during mechanical operation but comes into action when hydraulic operation is used and prevents the pistons from falling back again after it has been driven upwards to drive the control rod into the core. The upper end of the threaded spindle is journalled inside the hollow piston by a number of horizontally rotating, vertical-axis guide rollers, each mounted upon a cantilevered shaft projecting upwards from the top end of the threaded spindle, so that they bear on the inner, cylindrical surface of the piston. Thus, during normal operation, these rollers simply roll inside the hollow piston whereas, during emergency run-in of the control rod, they slide axiallu throughout virtually the full length of the hollow piston. Preferably, the length of each cantilevered shaft is at least twice the axial length of the rollers and the rollers are mounted in two or more different planes. The system of rollers on cantilevered shafts indicated is an effective substitute for the more commonly used sliding bearing of graphite, which is subject to high wear and is not very reliable inoperation.
