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.
