Abstract
Results from the studies of the rate of destruction by aqueous media of proposed barrier materials as well as the rate of leaching from proposed matrix materials are reported. A neutron activation analysis technique has been used exclusively for these measurements. Modest thicknesses of barrier material are adequate for “thousand year” security against water intrusion. The effect of temperature on the leach rate of the glass matrices studied is shown to be the predominant variable associated with the leaching medium. Conclusions based on the observed results are drawn.
Work performed under the auspices of the U.S. Dept. of Energy.
