A few selected activities being set forward by Institute for Disaster Reconstruction and Regeneration Research, Tohoku University, for restoration after Fukushima Daiichi Nuclear Accident will be shared with the audience in this session.

The first topic is “technology development for the restoration of living environments contaminated by radioactive materials”. The project aspires to develop technology for the restoration of living environments contaminated with radioactive materials. That is, decontamination technology for soil, technology effectively utilizing collected radioactive materials, methods for the cultivation of non-radioactive crops, or non-destructive (whole) monitoring technology for gamma radiation. The outcomes are offered to residents living in the areas damaged by Great East Japan Earthquake for their recovering from the disaster.

The second topic is “comprehensive radiation assessment of disaster affected animals”. Biological effects by long-term exposure of low dose/ low dose-rate radiation have been drawing scientific and social attention since the accident of Fukushima Daiichi Nuclear Power Station occurred. The presentation will introduce the activities in which biological samples were collected from livestock and Japanese macaques living within the ex-evacuation zone of the accident and biological effects were analyzed.

The third topic is “disaster response robots and remote technologies”. Remote operation in confined spaces with many obstacles is a tough mission for the disaster response robots. The talk introduces a snake-like long flexible robot applied for the Fukushima Daiichi Accident and its recent advanced technologies.

The fourth topic is “activities of Center for Fundamental Research on Nuclear Decommissioning”, where our approaches of fundamental research and human resource development to contribute to decommissioning of Fukushima Daiichi NPS will be introduced.
