Development of an emergency shutdown system for pebble bed reactors
Description
The development of an emergency shut down system for pebble bed reactors is described in detail. This shut down system consists fo small neutron absorbing spheres, which in case of a shut down are falling down on the surface of the core and due to their small size penetrating into the pebble bed. The feasibility of this shut down system is demonstrated and in a large number of detailed experiments the behaviour of this system is investigated. (orig.)

Es wird die Entwicklung eines Notabschaltsystems fuer Kugelhaufenreaktoren im einzelnen beschrieben. Dieses Abschaltsystem beruht auf der Verwendung von kleinen Absorberkugeln, die im Abschaltfall in die Kugelschuettung einrieseln und relativ gleichmaessig verteilt in der Kugelschuettung festgehalten werden. Die technische Machbarkeit des Systems konnte nachgewiesen werden und in vielen Einzeluntersuchungen die Eigenschaften dieses Abschaltsystems aufgeklaert werden. (orig.)
