Process for separation of fission and activation products from a gas atmosphere and device for carrying out the process
Description
Dust particles of concrete, earth, cement or silica gel are blown into the reactor containment to deposit fission and activation products which are situated in the reactor containment of the HTR after a fault. The container for storing the dust is connected via a pneumatic transport pipe through the reinforced concrete wall with the inside of the reactor building for this purpose. (RW)

Zur Ablagerung von Spalt- und Aktivierungsprodukten, die sich nach einem Stoerfall im Reaktorgehaeuse des HTR befinden, werden ueber eine Leitung Staubpartikel aus Betonit, Ton, Zement oder Kieselgel in das Reaktorgehaeuse eingeblasen. Der Staubaufbewahrungsbehaelter ist hierzu durch eine pneumatische Foerderleitung durch die Spannbetonwandung mit dem Innenraum des Reaktorgebaeudes verbunden. (RW)Files
