除染方法の評価や作業者の放射線防護対策を検討するために、避難指示区域において除染モデル実証事業が実施された。本報告は、このうち除染作業により除去された土壌等の除去物の仮置場の設計・建設および維持・管理など、当該実証事業で得られた技術的ノウハウを取りまとめたものである。

Removed contaminants including soil, grass and trees are to be stored safely at temporary storage facilities for several years, after which they will be transferred to a planned interim storage facility. The decontamination pilot project was carried out in both the restricted and planned evacuation areas in order to assess decontamination methods and demonstrate measures for radiation protection of workers. Fourteen temporary storage facilities of different technical specifications were designed and constructed under various topographic conditions and land use. In order to support the design, construction and monitoring of temporary storage facilities for removed contaminants during the full-scale decontamination within the prefecture of Fukushima, technical know-how obtained during the decontamination pilot project has been identified and summarized in this paper.
