Abstract

Numerical modeling of non-isothermal flow was conducted to examine the effects of perched water on thermally-driven moisture flow at the proposed Yucca Mountain (YM) nuclear waste repository, a site located deep in unsaturated, fractured volcanic rock. Our numerical modeling studies indicate that thermal loading from emplaced waste in the repository is not likely to have an effect on potential perched-water zones (PPZs) located far enough from the heat source. On the other hand, PPZs near the heat source will experience
