Confinement performance of Boda clay-stone formation, Hungary

Presented the results of the investigation programme - the so-called Short-term Programme, till 1999 - of Boda Clay-stone Formation, which is the potential host rock for HLW and SF disposal in Hungary. The poster illustrated the geological properties of BCF, the explorations in the former underground research laboratory, and listed the mineralogical and hydrogeological properties of the Boda Clay-stone. Furthermore, long term safety issues and the geotechnical suitability were highlighted. In the final conclusion it was mentioned, that after 1999 there were not carried out further explorations, but an overall and country-wide site screening was completed. Based on the results of the screening and the SPT a new site characterisation process started in 2003. (authors)
