Natural analogue studies on long-term behavior of engineered barriers

Mitsui, Seiichiro  

The Power Reactor and Nuclear Fuel Development Corporation (reorganized into the Nuclear Fuel Cycle Development Agency in 1998, merged with the Japan Atomic Energy Research Institute, and since 2005 has become the Japan Atomic Energy Agency) has been conducting natural analogue studies on the geological disposal system of radioactive waste since JFY1986. Here, we will provide an overview of the natural analogue studies on the long-term behavior of engineered barriers.
