In the frame of studies on geochemical perturbations in Boom Clay, two in-situ experiments within the HADES underground research laboratory in Mol, Belgium, were designed and installed. The first experiment aims at evaluating the oxidation that occurred around the underground laboratory, more specifically around the Test Drift and the Connecting Gallery. The second experiment aims at following the influence of oxidation on the pore water chemistry during and shortly after the excavation of the PRACLAY gallery. The same experimental set-up will be used to follow-up the geochemical changes that occur during the long-term heater test to be performed within the PRACLAY gallery. This report describes the design and installation of all in-situ experiments performed within the study on geochemical perturbations in Boom Clay (oxidation & heat).
