The container of a nuclear reactor has a specific number of dry sleeves or sleeves which are not in contact with the pressurized liquid, which are arranged inside guide tubes which extend between a hermetically closed control table and the instrumentation or central-control tube of the fuel assembly inside the reactor container. The guide tube and the dry sleeve are joined together above the table and by means of the combination of a hermetic closure casing and a permanent alloy moulding material tube accessory. |
