Abstract

The effective diffusivity of carbon dioxide through various tuff samples is reviewed. The effective diffusivities of carbon dioxide through "G" tunnel tuff, the lower non-lithophysal zone of the Topopah Spring tuff (outcrop sample of proposed nuclear repository site layer), USW H-6 test well tuff, the lower lithophysal zone of the Topopah Spring tuff (outcrop sample of the layer right above the proposed repository) and Tiva Canyon tuff samples (proposed repository layer) have been evaluated. Empirical correlations were reported for each tuff to estimate the effective diffusivity of carbon dioxide through them. The effective diffusivity of carbon dioxide through all the tuff samples increased with temperature and decreased as the moisture content increased.
