ABSTRACT:
The control assembly of a nuclear reactor according to the invention comprises a sleeve stationarily mounted in the fuel core of the reactor and accommodating a casing movable therein. The casing accommodates two superposed concentric sections formed by fuel and absorbing elements, respectively. Approximately at the boundary between the sections, the casing is provided with openings adapted to remove a part of a cooling medium flowing around said sections and into a space formed between the casing and sleeve. In order to control the flow rate of this part of the cooling medium, depending on the position of the casing relative to the fuel core of the reactor, a throttle means disposed in the zone of the section formed by the absorbing elements is provided.
