JAEA has developed evaluation techniques for characterization of solute transport in the mudstone through laboratory and in-situ tests. This study reports an overview of in-situ tracer tests implemented for fractures and rock matrices in the mudstone at Horonobe Underground Research Laboratory (URL).
