    Research outputpeer-review


    In the framework of the Belgian in situ research program on the disposal of high-level nuclear waste in a clay formation, an underground test facility is operated. Recently, this facility has been extended by a second access shaft and a connecting gallery. The construction works have been subject to an extensive modeling and monitoring program to assess the performance of an industrial gallery excavation and construction technique at unprecedented depths, and to assess the response of the clay formation to these works. In this paper we present how the instrumentation program has been designed and implemented, the actual performance of the in-struments, and some selected measurement results.
