Technological Lessons from the Fukushima Dai-Ichi Accident

Abstract : In March 2011, northern Japan was subjected to a devastating earthquake and tsunami. One of the many secondary effects of these disasters was a loss of control of the Fukushima Dai-Ichi nuclear plant. This led to the dispersal of radioactive material into the environment, both immediately and over the following months. The focus of this research is on how various technologies were used to ascertain the extent of radioactive contamination, to prevent the spread of radioactivity that had already dispersed into the wider environment, to decontaminate areas or items, and to store radioactive material for extended periods, all while limiting human exposure to radiation. By capturing lessons regarding how technologies were used successfully, as well as identifying capability gaps that could have been alleviated through the better use of technologies or the development of novel technologies, this research is intended to help improve technological preparedness for any future radiological or nuclear incidents.
