Engineers at SRS are evaluating the Low-Curie Salt Process which is aimed at initially withdrawing the interstitial liquor followed by dissolution of the salt cake. Partitioning of the cesium is predominantly within the interstitial liquor; consequently a separation based on activity can be effected. Laboratory experiments using simulants from SRS tanks have been performed along with thermodynamic simulations. Results indicate that insoluble layers such as Al(OH) 3 and/or cancrinite may form and hinder the dissolution processes. The effectiveness of the Low-Curie Salt Process may be reduced based on layer formation and the distribution of the interstitial liquor within the waste.
