A high-temperature gas reactor control rod is provided that does not degrade the joining state between the control rod elements even when stress is applied thereto, and that can improve the safety of the high temperature gas reactor remarkably by improving the heat resistance thereof. The high-temperature gas reactor control rod has a plurality of control rod elements (1) each having a neutron absorber (7) between an outer cylinder (9) and an inner cylinder (8) that form a double cylindrical tubular shape, the control rod elements (1) joined to each other in a vertical direction, characterized by : a columnar support member (2) for supporting at least the neutron absorber (7), disposed in the inner cylinder (8); and joining means for joining to another control rod element (1), provided at at least one of upper and lower ends of the support member (2). |
