摘要

The apparatus for shutting down and/or regulating a gas-cooled nuclear reactor comprises reflector rods (2) consisting of several sections (1) which consist of outer and inner cover pipes bounding an annular space with absorber elements. The chain (6) suspending the reflector rod is driven by means of a stepping motor (13).
