Control-bar driver for a core-reactor and method to guide a control-bar into a reactor-core of a core reactor

The control-bar-driver (2) includes a driver-housing (8), in which a control-bar-carrying-element (40) is movable between a base-position and a normal end-position. The control-bar-carrying-element (40) is conducted with a part-section into a throttling-liner (30), where through the throttling-liner...

Summary:The control-bar-driver (2) includes a driver-housing (8), in which a control-bar-carrying-element (40) is movable between a base-position and a normal end-position. The control-bar-carrying-element (40) is conducted with a part-section into a throttling-liner (30), where through the throttling-liner (30) a free flowing-cross-section, which varies according to the actual position of the control-bar-carrying-element (40), for a pressure-fluid is formed. Through this construction, in a rapid switching-off, in which the control-bar-carrying-element is moved hydraulically through a pressure-fluid, the flowing-resistance for the pressure-fluid is changed, and especially becomes smaller, when the control-bar-carrying-element (40) arrives at the normal upper end-position. Thus a braking action of the control-bar-carrying-element is performed before the arrival of the normal position, so that the mechanical loading in the braking are small. The change of the flowing resistance is preferably performed through the chang
