OSTI ID:4821376

The nuclear reactor has vertical fuel element channels. The top of the reactor is provided with a plurality of charging holes, in each of which may be mounted the device able to charge or discharge a number of adjacent channels. The device comprises guiding means having the form of a collapsible parallelogram constituted by parts jointed together and is mounted on the lower extremity of a charging chute which is rotatably mounted in the charging hole of the reactor vessel. For charging a fuel element, the device is let down by a cable-supported grip firstly through the charging chute, then along guiding means on the upper sloping part of the parallelogram system, and finally down into the reactor channel. During all these movements the fuel element remains vertical. Preferably, during the movement along the sloping part of the parallelogram system and the charging chute, the fuel element is enclosed in a tuhular protecting container having at its upper end laterally mounted rollers that slide in rails provided in the guiding means, viz in the charging chute and the said sloping part of the parallelogram system.
