The leaching kinetics of inactive caesium from cylindrical cement specimens containing caesium sulphate was studied at different temperatures and thicknesses. In all cases the square root of time plots were reasonably linear at least initially in accordance with Fick's Law and the diffusion coefficients were estimated. The sorption of caesium ion from aqueous solution by cement was studied by equilibrating cement granules with aqueous caesium sulphate. Leaching of specimens containing strontium-90 and sodium nitrate was performed under exposure to atmospheric carbon dioxide. Low temperature differential scanning calorimetry measurements of hydrated cement were undertaken to obtain information about the melting behaviour and hence the state of water within the cement. Cellulose films containing calcium sulphate or strontium sulphate were leach tested in frequently renewed water at 25 C. The elution curves follow a square root of time law in conformity with the Higuchi equation. Ellution tests of sodium chloride or strontium sulphate embedded in epoxy resin indicated that strontium sulphate elution was generally similar to cellulose. Theoretical work involved the formulation of new models capable of describing soluble salt elution.
