General question: Are there any considerations (or on-going heater tests already) at lower temperature (closer to what are the proposed thermal limits for a DGR in crystalline rock of approximately 100 degrees C)? As someone who is not in the EBS field, I would be curious to know how the swelling potential/capacity reduction at the interface would be impacted if exposed to much lower temperatures (presumably, the reduction in swelling capacity would be smaller, as the extent of drying and water loss within the bentonite clay at the interface would be lessened).
There is a heater test at the Honorobe site (Japan; clay rock) at 100C. I think their interest is to study the Kunigel V1 bentonite at temperatures lower than 100C. I'd also expect less of a temperature effect at T<100C in light of the FEBEX-DP work.
