Fukushima Daiichi

At the time of the accident at Fukushima Daiichi nuclear power plant in 2011, I was living in Iwaki City with my two children and my husband. With our home damaged by the tsunami and the deteriorating status following the situation at the nuclear power plant, we spent 2 years as evacuees before returning to Iwaki City. Subsequently, I decided to work as a radiation counsellor in the Suetsugi district of Iwaki City. I would like to describe my experience of taking measurements and helping to communicate with the residents while respecting the lives of local people.

Fukushima Daiichi

This study explores the root causes of the Fukushima Daiichi disaster and discusses how the complexity and tight coupling in large-scale systems should be reduced under emergencies such as station blackout (SBO) to prevent future disasters. First, on the basis of a summary of the published literature on the Fukushima Daiichi disaster, we found that the direct causes (i.e., malfunctions and problems) included overlooking the loss of coolant and the nuclear reactor’s failure to cool down. Second, we verified that two characteristics proposed in “normal accident” theory—high complexity and tight coupling—underlay each of the direct causes. These two characteristics were found to have made emergency management more challenging. We discuss how such disasters in large-scale systems with high complexity and tight coupling could be prevented through an organizational and managerial approach that can remove asymmetry of authority and information and foster a climate of openly discussing critical safety issues in nuclear power plants.
