Abstract

Since the Fukushima Daiichi nuclear power plant accident caused by the Tohoku Region Paciˆc Coast Earthquake on March 11, 2011, decontamination work has been conducted in the surrounding environment within the Fukushima prefecture. Removed contaminants including soil, grass and trees are to be stored safely at temporary storage facilities for up to three 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 diŠerent technical speciˆcations 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 identiˆed and summarized in this paper.

为清除污染物而设的临时贮存设施的设计、建造及监察

自2011年3月11日日本东北地区太平洋海岸地震导致福岛第一核电站事故以来，福岛县周边环境的净化工作一直在进行。除去的污染物，包括土壤、草和树木，将被安全储存在临时储存设施中长达三年，之后将被转移到计划中的临时储存设施。除污试点项目在限制疏散区和计划疏散区进行，以评估除污方法和示范工人的辐射防护措施。根据不同的地形条件和土地利用情况，设计建造了14个技术规格为diŠerent的临时储存设施。为了支持福岛县全面除污期间被清除污染物临时储存设施的设计、建造和监测，本文对除污试点项目期间获得的技术诀窍进行了确定和总结。
