Research Objectives
The U.S. Department of Energy is actively investigating the technical feasibility of permanently disposing high-level nuclear waste in an appropriate repository proposed for the unsaturated zone (UZ) at Yucca Mountain, Nevada. The objectives of this study are to evaluate the transport of radioactive solutes and colloids under ambient conditions, from the proposed repository horizon to the water table, and to determine processes and geohydrological features that significantly affect radionuclide transport.
