Outline

The purpose of the workshop is to discuss the alteration processes of bentonite with iron by means of experimental, theoretical and natural analogue approaches. The workshop also focuses on the behavior and performance of altered bentonite in the disposal environment. The symposium will both encourage international cooperation in the field.

Hosted by:

Institute of Nature and Environmental Technology, Kanazawa University
Lab. of Environmental Geology, Graduate School of Engineering, Hokkaido University
Lab. of Nuclear and Environmental Materials, Graduate School of Engineering, Hokkaido University
