Hydraulic Control Rod Drive for Water-Cooled Nuclear Reactors, Particularly Heating Reactors.

摘要

This invention consists of a hydraulic control rod drive for water-cooled nuclear reactors, particularly heating reactors, having a reactor pressure vessel and having a reactor core supported in it, consisting of a fuel assembly field in an upright configuration and control rods supported so that they can be inserted into or withdrawn from interspaces between the fuel assemblies, in or counter to the direction of gravity, whereby drive rods of the control rods are provided with hydraulic piston-cylinder systems, to which the cooling water can be supplied from below as the working fluid through reactor-internal fluid lines, whereby the cooling water reservoir is used as a hydraulic drain. 13 figs.
