Abstract
For gas-cooled pebble-bed reactors, an absorber element in the form of a hollow, helical spiral coil is proposed, which moves directly through the pebble bed essentially through rotary motion. This form not only facilitates the penetration into greater depths of the pebble bed, but also has a substantially greater absorber effect as compared to the known, essentially cylindrical absorber rods with the same absorber volume, so that the number of absorber elements can be reduced.
