Abstract: The Power Reactor and Nuclear Fuel Development Corporation (PNC) has developed an in-situ test facility in the Kamaishi Mine to resolve technical issues in disposal of radioactive wastes in fractured crystalline rock. This paper presents the results of a discrete-fracture simulation of flow to a 50-m long drift in the experimental area. The results show that realistic flow simulations can be prepared using readily obtainable data under Japanese geological conditions.
