Diffusion of tritiated water and chloride in basalt-bentonite mixtures

摘要: Effective diffusion coefficients of tritiated water and chloride (/sup 36/Cl) were measured in mixtures crushed basalt bentonite as functions temperature (20 to 90/sup 0/C) mixture bulk density (1.5 1.9 Mg/m/sup 3/). A quick-freeze technique was used halt the process so tracer distributions could be determined by slicing core analyzing slices liquid scintillation methods. Linear multiple-linear regression analyses performed on both data sets. The equations then predict coefficient values outside range densities these experiments. predicted agree very well with published data. Correlation highly significant for elements. Dependence clay much larger than tritium.
