Abstract

Construction and operation of “interim storage facilities” have started these two years to contain the nuclide contaminated soils and wastes generated through decontamination works to reduce the radiation caused by the Fukushima Daiichi Nuclear Power Plant accident which occurred in 2011. Since the interim storage facilities require 30-year barrier performance against nuclide release into the geoenvironment, application of double liner system consisting of clay liner and geomembrane is considered, similar to the conventional waste landfills. Failsafe measures for safety against the risk of damage to the barrier system is also required. The Geomembrane Technical Committee of the Japan Chapter of the International Geosynthetics Society proposed proper design of barrier systems for such interim storage facilities based on the investigations and reviews of current existing technologies. This paper presents the barrier materials and their configurations applied to the interim storage facilities.
