Studies of dynamic and static leaching of cemented and uncemented sorption material loaded with iodine-129

Creators

Description

Leaching tests with water and brines were conducted on Ac 6120 iodine sorption material (12 wt.% Ag) in order to improve the assessment of the behavior of radioactive waste stored in a repository mine (salt or iron ore. ). As a result of the dynamic and static leaching tests, the leached fraction of I-129 in the uncemented material was found to be < 10-1%, while that of the cemented iodine sorption material was found to be < 10-2%. After ordinary steel had been added to the cemented sorption materal, the leached fractions found were identical to those measured in uncemented material. The addition of stainless steel had only little influence on the leached fraction. (orig.)

Abstract (German)

Zur besseren Beurteilung des Verhaltens von radioaktivem Abfall bei der Endlagerung in einem Endlager-Bergwerk (Salz oder Eisenerz) wurden ueber einen laengeren Zeitraum Auslaugversuche mit Wasser und Salzloesungen am Iodsorptionsmaterial AC 6120 (12 Gew.% Ag) durchgefuehrt. Als Ergebnis der statischen und dynamischen Auslaugversuche wurde der Auslauganteil des nicht zementierten Materials an I-129 mit < 10-1% bestimmt, waehrend der des zementierten Iodsorptionsmaterials < 10-2% betrug. Nach Zugabe von Normalstahl zum zementierten Sorptionsmaterial wurden Auslauganteile wie beim nicht zementierten Material gemessen. Eine Zugabe von Edelstahl hatte nur geringen Einfluss auf den Auslauganteil. (orig.)
