The proposed session will be dedicated to the recent innovative technological developments and applications of geosynthetics to be used against nuclide contaminations. Variety of innovative technologies on geosynthetics engineering (materials, systems, designs, concepts, managements, etc.) have been accumulated since Fukushima Daiichi Nuclear Power Plant accident at 2011 East Japan earthquake and tsunami, to try to overcome against nuclide contaminations. They include numerous numbers of temporary storage sites where the geomembranes and GCL were installed to contain the bags with nuclide contaminated soils and wastes generated from de-contamination works, and where required are several challenges such as immediate installations sometimes over soft grounds, application of hydraulically-impervious and air-permeable geosynthetics because of the degradation of organic fractions, wind-resistance exposed geomembranes etc. Geosynthetics are also applied at the site of damaged nuclear power plants to prepare nuclear decommissioning. The session will attract the papers on these innovative technologies which are worth of being presented at the conference, but of course will never limit to the Fukushima experiences: The contributions which are not related to Fukushima recovery are strongly welcomed to exchange ideas and experiences. The session will be organized by IGS Japan Chapter as well as IGS Technical Committee on Barrier Systems.
