Geology, seismic activity and groundwater conditions at six potential disposal sites for radioactive waste from Risø, Denmark

In 2003 it was decided by the Danish Parliament that low and intermediate-level radioactive waste from the Danish nuclear research facility, Risø, is to be stored at a permanent disposal site (Ministeriet for Sundhed og Forebyggelse 2008; Gravesen et al. 2012a). Both the issue of storage and the selection of potential sites have caused considerable public debate. In this paper we report on the most recent geological investigations intended to further improve the database for the selection and decision process, although no conclusions have been drawn at this stage.
