After the Great East Japan Earthquake on March 11, 2011, the Tokyo Electric Power Company Fukushima Daiichi Nuclear Power Plant accident occurred. The Fukushima prefectural government decided to launch the Fukushima Health Management Survey; Fukushima Medical University was entrusted to design and implement the survey. The survey process and development is described from the standpoint of its background and aim. An overview of the basic survey and 4 detailed surveys is briefly provided. Issues related to the survey are discussed from the perspective of supporting the Fukushima residents.

<p>A large amount of radionuclides has been released into the environment by the accident of Fukushima Daiichi Nuclear Power Plant (1F). About 10 years have passed since the accident, and the effects have significantly decreased. However, it should be noted that they still remain in spite of their tiny contributions. On the other hand, there is now an important demand that the radioactive materials should be monitored continuously due to the decommissioning work at 1F being carried. Thus, we evaluate the behavior of the radioactive materials in seawater around the port of 1F using both the monitoring result measured by TEPCO (Tokyo Electric Power Company Holdings) and the simulation results on seawater flow. In this presentation, we introduce the simulation methods and report the insights through the monitoring results. Finally, we reveal the mechanism of spreading the materials in the seawater around 1F port by evaluating with both the monitoring data and the simulation results.</p><p> </p>

On March 11, 2011, Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant (NPP) was hit by a tsunami caused by the Tohoku-Pacific Ocean Earthquake, resulting in nuclear accidents in Units #1 to #4. With the aim of improving the safety of NPPs worldwide, we summarize the lessons that have been learned following a thorough analysis of the event and make specific proposals for improving the safety of such facilities. The author has been involved in investigating the causes of the accidents and developing countermeasures for other NPPs in Japan as a member of the Committee for the Investigation of Nuclear Safety of the Atomic Energy Society of Japan [1], an advisory meeting member of NISA with regard to technical lessons learned from the Fukushima Daiichi NPP accidents, and a Safety Evaluation Member of NISA for the other NPPs in Japan [2].
