Recent Development of Underground Scientific Experimental Research for the High Level Waste Disposal

Recent International Trend in Clay Stones

Abstract

This paper summarizes the recent trend of world underground laboratories for the radioactive waste disposal. The research is now developing in the clay stone type, though they meet the difficulty of very low mobility or diffusivity of chemical components in the fluid in clay stone. In Mont Terri of Switzerland, the researches of fluid and clay stone are suggested to contribute to the public acceptance (PA) . It is also important to introduce the information management to disclose and exchange of research information with advanced information systems. The fluid and rock interaction research of clay stone can contribute to the carbon dioxide sequestration in underground, the pollution of soil and ground water, and sealing potential in hydrocarbon exploration that are recently important issues that we have to solve.
