Thermohydrologic behavior and repository design at Yucca Mountain
Radioactive decay of nuclear waste emplaced at Yucca Mountain will produce an initial heat flux many times larger than the heat flux in some natural geothermal systems. This heat flux will change the thermal and hydrologic environment at Yucca Mountain significantly, affecting both the host rock and conditions within the emplacement tunnels (drifts). Understanding the thermohydrologic behavior in this coupled natural and engineered system is critical to the assessment of the viability of Yucca Mountain as a nuclear-waste repository site and for repository design decision-making. We report results from a study that uses our multi-scale modeling approach to explore the relationship between repository design, thermohydrologic behavior, and key repository performance measures.
