Nonisothermal hydrologic transport study at the Apache Leap Tuff site

OSTI ID:139508
A field-scale heater test is proposed for investigating coupled hydrologic, thermal, and mechanical processes in unsaturated fractured rock related to the disposal of high-level radioactive waste in an underground repository. Observations of fluid flow and solute transport in nonisothermal, unsaturated, fractured rock under controlled, experimental conditions are limited, and the proposed experiment will provide data sets for use in verifying conceptual and computer models related to HLW isolation in an environment where substantial quantities of heat energy are produced by HLW. Previous nonisothermal experiments with tuff have demonstrated the need for additional field scale experiments conducted under controlled initial and boundary conditions using more sophisticated and reliable monitoring systems. 8 figs., 1 tab.
