“…This test is located in a mined 47.5 m long drift and contains nine canister heaters, each with a maximum power of 7.5 kW. Twenty-five "wing heaters" for control of boundary conditions were placed in horizontal boreholes on each side of the drift with a maximum heat output of 143 kW (Hardin and Chestnut, 1997). Thermal, hydrologic, mechanical, and geochemical changes are monitored using more than 80 instrumented boreholes.…”

“…Limit thermally induced micro-cracking in the less ductile crystalline rock types (e.g., crystalline, igneous or metamorphic), to avoid degradation of in situ mechanical properties or creation of flow paths. For example, the Yucca Mountain concept included a nominal limit of 200C for the host rock, to limit thermal degradation of in situ rock characteristics (Hardin et al 1997). Crystalline rock could exhibit this mode of degradation, but with the use of clay buffers (as in this study) the clay temperature limit is controlling.…”

“…Such processes may be sensitive to threshold temperature effects, such as the local boiling point of water, or they may be sensitive to thermal gradients. Boiling accelerates solute transport and chemical precipitation (which are THMC processes) while thermal gradients can facilitate processes such as thermally driven Onsager transport couples in low-permeability media (discussed by Hardin et al 1997). …”
