Abstract

Boom clay is a potential geological host formation for High Level Nuclear Waste in Belgium. Impact of thermal loads may play an important role on this clay formation. To this aim, heating pulse tests on intact borehole samples were carried out using an axi-symmetric heating cell. Heating tests under nearly constant volume conditions and different target temperatures (maximum 85°C) were performed under controlled hydraulic boundary conditions. Selected test result are presented and afterwards calibrated and simulated using CODE_BRIGHT.
