The facility construction of the Okuma Analysis and Research Center is being promoted on the basis of the first phase facilities and the second stage facilities in accordance with the road map prescribed by the government in order to promote the decommissioning of the Fukushima Daiichi Nuclear Power Station is there. As the first phase facility, we designed "Radioactive Material Analyses and Research Facility Laboratory-1" which analyses mainly low-medium radiation doses radioactive waste (rabble, logging tree (incineration ash), dismantled waste etc), "Administrative Building" which is an office building, Site decontamination, Exterior and Utility equipment, etc. In addition to radiation protection and prevention of pollution at the time of construction, it is designed to reduce radiation exposure from outdoor pollution sources of residents after the facility starts to operate, shielding for the reliability of the analysis results, suppression and prevention of outside air inflow, etc.
