International Symposium on Remediation Of Radioactive Contamination in the Environment
Date: July20, 2017

The "International Symposium on Remediation of Radioactive Contamination in the Environment" was held at the Toho Minnano Bunka Center in Fukushima City on Thursday, July 20, 2017. It was sponsored by the Society for Remediation of Radioactive Contamination in Environment (SRRCE) and co-sponsored by Ministry of the Environment.

This symposium was staged in conjunction with the sixth research presentation conference of SRRCE. Invited speakers were Dr. Hans Codée, former director of the Netherlands Radioactive Waste Central Organization (COVRA), Dr. Mark Zheleznyak, Professor of Institute of Environmental Radioactivity of Fukushima University, Mr. Ryutaro Yatsu, president of Japan Environmental Storage and Safety Corporation (JESCO) and Mr. Daisuke Uesako of Japan’s Ministry of the Environment.

At the symposium, firstly Mr. Uesako reported on the outline and achievements of the decontamination project in Fukushima Prefecture, the outline and current status of the Interim Storage Facilities and related topics followed by Dr. Zheleznyak who gave an outline of the accident and pollution situation at the Chernobyl nuclear power plant, in comparison with that of the Fukushima nuclear power plant. In addition, he described a modelling study on the diffusion of radioactive substances by the hydrological system at Chernobyl, explaining the modelling study on diffusion of radioactive substances by the hydrological system in Fukushima prefecture which is currently being conducted.

For the next, Dr. Codée, former director of COVRA, presented the approach and outline of interim storage facilities for radioactive waste in the Netherlands. It is currently placed in containers under the concept of recycling and reusing the material after a decay period of radioactive nuclides. For contaminated soil in Fukushima, various options such as volume reduction can be considered. In addition to this, he talked about the idea of storing cesium 137 during a decay period of 30 (or 120) years, and then recycling/reusing the material for foundations of artificial islands, levees, aircraft runways, and solar facilities.

Finally, President Yatsu of JESCO introduced past progress and future developments for Interim Storage Facilities. He covered the situation of Interim Storage Facilities currently operated in Futaba Town and Okuma Town, and anticipated issues, etc. At the closing, he gave an outline of JESCO and its relationship with Interim Storage Facilities.

The 3rd IAEA-MOE Experts' Meeting
Date: April17-21, 2017

The 3rd IAEA-MOE Experts' Meeting on Environmental Remediation of Off-Site Areas after the Fukushima Daiichi Nuclear Power Station Accident was held in Tokyo and Fukushima from 17 -21 April 2017.
Since Ministry of the Environment(MOE) completed the whole area decontamination in Special Decontamination Area(SDA) as the end of March 2017, based on the Decontamination Implementation Plan, the meeting covered four topics as below;

  • The outcomes of the environmental remediation works carried out at the off-site areas affected by the accident at TEPCO’s Fukushima Daiichi Nuclear Power Station
  • The lessons learned on remediation based on data collected in Date City;
  • The evaluation of the effects of the whole area decontamination
  • The way of sharing the results from the applied technologies for decontamination and waste volume reduction with the international community.

As the summary shows, IAEA team gave some proposal of suggestions to MOE for further consideration in progressing the environmental remediation and related works.
IAEA team also concluded that significant progress has been made with the remediation in the offsite areas affected by the accident, and that steady progress on the ISF construction and soil/waste transportation to this facility has been made.
Site visits to review the activities on soil-recycling conducted in Minami-Soma City and the incineration of combustible waste in a dedicated facility in Date City took place during the last day of the week.
