Abstract

« Le 11 mars 2011, le district Nord-Est du Japon a été frappé par un tremblement de terre massif suivi d’un tsunami majeur et d’une série d’accidents à la centrale nucléaire de Fukushima avec fuites d’éléments radioactifs ». Tel est le message que le professeur Kanazawa, président du Science Council of Japan (SCJ) adressa quelques jours après la catastrophe aux présidents des académies des sciences étrangère …

Abstract

Following the Fukushima nuclear accident, a large volume of monitoring data has been collected about the soil, air, dust, and seawater, along with data about an immense number of foods supplied to the market. Little is known, however, about the effect of radioactive fallout on agriculture, information about which is vital. Although more than 80% of the damaged area is related to agriculture, in situ information specifically for agriculture is scarce. This book provides data about the actual movement and accumulation of radioactivity in the ecological system—for example, whether debris deposited on mountains can be a cause of secondary contamination, under what conditions plants accumulate radioactive cesium in their edible parts, and how radioactivity is transferred from hay to milk. Because agriculture is so closely related to nature, many specialists with different areas of expertise must be involved in answering these questions. In the case of rice, researchers in rice cultivation as well as in soil, hydrology, and radioactivity measurement are working together to reveal the paths or accumulation of radioactivity in the field. For this purpose, the Graduate School of Agricultural and Life Sciences of The University of Tokyo has diverse facilities available throughout Japan, including farmlands, forests, and meadowlands. Many academic staff members have formed groups to conduct on-site research, with more than 40 volunteers participating. This book presents the data collected from the only project being systematically carried out across Japan after the Fukushima accident.

Abstract

“On March 11, 2011, the North-East of Japan was struck by a huge earthquake followed by a major tsunami and a series of accidents that took place at the nuclear power site at Fukushima, with emissions of radioactive elements”. This was the message addressed by Prof. Kanazawa, President of the Science Council of Japan (SCJ), only a few days after the catastrophe, to his colleagues Presidents of the Science Academies, adding that he nourished the hope the “the academies would continue in the future to help with the necessary rehabilitation work”. The idea arose immediately to set up an ad hoc academic Working Party, with the assigned mission to analyse the events that had taken place in Japan, to make a status report regarding seismic and nuclear risks both in metropolitan France and in overseas territories and to draw conclusions and make recommendations as deemed appropriate to the situation. The academic Working Party comprised three separate sub-groups, each dealing with one of the three aspects – seismic, nuclear and medical – of the drama as it unfolded. For each of these components, objects of the three parts of this report, the analysis of observed events in Fukushima was supplemented by a reflection o the strengths and weaknesses of these areas in France, in order to formulate the necessary recommendations and to answer scientific and societal question public arises. Although uncertainties remain and that new information still come each month to enrich the record, the enclosed reports seemed complete enough to be published in the state, after the anniversary of this tragedy that will long continue to challenge us.

Abstract

This book covers essential aspects of transmutation technologies, highlighting especially the advances in Japan. The accident at the Fukushima Daiichi Nuclear Power Plant (NPP) has caused us to focus attention on a large amount of spent nuclear fuels stored in NPPs. In addition, public anxiety regarding the treatment and disposal of high-level radioactive wastes that require long-term control is growing. The Japanese policy on the back-end of the nuclear fuel cycle is still unpredictable in the aftermath of the accident. Therefore, research and development for enhancing the safety of various processes involved in nuclear energy production are being actively pursued worldwide. In particular, nuclear transmutation technology has been drawing significant attention after the accident. This publication is timely with the following highlights: 1) Development of accelerator-driven systems (ADSs), which is a brand-new reactor concept for transmutation of highly radioactive wastes; 2) Nuclear reactor systems from the point of view of the nuclear fuel cycle. How to reduce nuclear wastes or how to treat them including the debris from TEPCO’s Fukushima nuclear power stations is discussed; and 3) Environmental radioactivity, radioactive waste treatment and geological disposal policy. State-of-the-art technologies for overall back-end issues of the nuclear fuel cycle as well as the technologies of transmutation are presented here. The chapter authors are actively involved in the development of ADSs and transmutation-related technologies. The future of the back-end issues in Japan is very uncertain after the accident at the Fukushima Daiichi NPP and this book provides an opportunity for readers to consider the future direction of those issues.
