OSTI ID:4823831

A means is described for charging or discharging the fuel elements in a homogeneous gas cooled reactor. The vertical reactor channels are grouped, so that each group is served by a charging arm reaching any channel of the group. Each of these charging arms is positioned in a vertical tubular charging chute passing through the biological shielding situated above the reactor vessel and through the pressure vessel wall. This arm is connected above the shield to a remote control head enclosing means for controlling the different movements of the arm. The head is removable so that it can be connected with any one of the charging arms. A second shielding is placed above the space within which the head can move, this shielding being provided with openings in alignment with the different lower charging chutes, upper charging chutes passing through these openings. The remote control heat container is gas tight and able to withstand the same working pressure as the reactor pressure vessel, which is in communication with the container. (NPO)
