Abstract

Fukushima Daiichi nuclear power plant was damaged by huge tsunami in the 2011 Great East Japan Earthquake. Decommissioning of the nuclear plant was presented as an urgent issue, but many difficulties persist in relation to the decommissioning process. Geotechnical engineering methods, e.g. a cutoff wall for decreasing the inflow of ground water into the plant and cover material of low radiation waste have already been applied to the site. Furthermore, we believe there are many more geotechnical engineering methods and materials that are useful for decommissioning the post-accident nuclear plant. A group of Japan Geotechnical Society researchers started to study an education system emphasizing the application of geotechnical engineering for post-accident nuclear plants under the Ministry of Education, Culture, Sports, Science and Technology, Japan. This education system is based on the new concept of 'Decommissioning Geotechnical Engineering'. This paper presents the concept of "The Decommissioning Geotechnical Engineering" and examples of Decommissioning Geotechnical Engineering technologies.
