Paper Abstract

The disposal of high radioactive waste in underground repository sites is a complex and complicated topic due to the strong heat generation. At the Mont Terri URL (Underground Research Laboratory), which is located in a potential clay host rock in Switzerland, a special heater test is currently performed to investigate the heat impact on the clay behavior. A fiber optic measurement system has been developed in order to measure the temperature evolution around the heat sources that have a maximum temperature of 100°C as well as the induced rock deformation due to the thermal expansion of the clay. The system as well as some first results will be described.
