      Natural Convection in Tunnels at Yucca Mountain and Impact on Drift Seepage
      Nuclear Technology Jun
      The decay heat from radioactive waste that is to be disposed in the once-proposed geologic repository at Yucca Mountain will significantly influence the moisture conditions in the fractured rock near emplacement tunnels (drifts). Additionally, large-scale convective cells will form in the open-air drifts and will serve as an important mechanism for the transport of vaporized pore water from the fractured rock in the drift center to the drift end. Such convective processes would also impact drift seepage, as evaporation could reduce the buildup of liquid water at the tunnel wall. Characterizing and understanding these liquid water and vapor transport processes is critical for evaluating the performance of the repository, in terms of water-in
