Abstract

This report brings together the results of the CACTUS project, which took place from 1990 to 1993 in the underground facilities of the Belgian nuclear research centre (CEN/SCK) at Mol. Each CACTUS experiment consists of six small diameter boreholes, arranged around a central heater buried in a vertically drilled hole. Each experiment provides in situ measurements of the thermo-hydro-mechanical behaviour of a deep clay formation, subject to a temperature variation similar to that created by stored radioactive waste canisters. Two experiments of similar geometry have studied the behaviour of the clay formation during a one-year heating period, followed by a one-year cooling period. These have also provided good quality measurements regarding the perturbations in the clay during the excavation of the central borehole.
