"Towards Promotion of Steady Environmental Regeneration and Decommissioning of Reactors"
It will soon be eight years since the accident occurred at TEPCO's Fukushima Daiichi Nuclear Power Plant. State-run decontamination work on the ground surface in Fukushima was completed by the end of FY 2016, and the restoration of the temporary storage areas is required for the time being.Decontamination integrated with infrastructure development in the "Specific Reconstruction and Reclamation Base Area" within Fukushima's difficult-to-return zone has been implemented by the government and its affiliated organizations including the Ministry of Environment, local municipalities, and operatorssince December 2017.Since the land acquisition for the interim storage facility has progressed, construction of receiving/sorting facilities and soil storage facilities that began in November 2016 is steadily under way.In addition to the safe and early operation of receiving/sorting facilities and soil storage facilities, the construction of facilities necessary for transportation of the soil and demonstration projects for volume reduction and reuse of soil, etc., which will reduce the final disposal, are required, and those movements from now on are to be watched.
While it might take 40 years to complete the decommissioning of the Fukushima Daiichi Nuclear Power Plant, the influx of contaminated water into the reactor building is prevented by the groundwater bypass sub drains and the frozen soil barrier walls.As regards the decommissioning of the reactors, removals of debris and retrievals of nuclear fuels in the spent fuel pools are to be conducted, followed by removals of nuclear fuel debris.Utilization of robot technology that Japan has as its strength is indispensable for this decommissioning operation. In order to accelerate the work, international collaborative research centers for decommissioning have also been set up, in which domestic and foreign experts analyze the behavior of radioactive materials and investigate nuclear fuel debris.
While full-scale transportation of removed soils and full-scale construction & operation of interim storage facilities have progressed as mentioned above owing to the measures against environmental radioactivity and waste disposal, advanced nuclear technology must be maintained and succeeded so that TEPCO Fukushima Daiichi Nuclear Power Station and other aging nuclear power plants can smoothly and safely be decommissioned. Therefore, development of relevant technologies and cultivation of human resources are required.
The Environmental News will hold RADIEX 2018 (Environmental Radioactivity Measures & Radioactive Waste Disposal International Exhibition) under the theme, "Towards Promotion of Steady Environmental Regeneration and Decommissioning of Reactors", in order to respond to these movements.
We do wish you to understand the objectives and participate in this exhibition.
