<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>

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.

Of all things relevant to the Great East Japan Earthquake, what drew the highest degree of attention from not only Japan but elsewhere around the world was the Fukushima Daiichi (No.1) Nuclear Power Plant’s nuclear power accidents that bears comparison with Chernobyl’s. During the subsequent four months, though this nuclear plant has not gone critical again, the leakage of radioactive materials from within the plant’s compounds continues. The possibility of another major accident happening, e.g. hydrogen explosion, breaking of containment vessel, in which radioactive materials would once again be strewed over the peripheral districts is not totally eradicated, albeit not so high. Given such a situation, the JDR Editorial staff has decided to examine the developments since the outbreak of the Great East Japan Earthquake and furnish the readers with updated information about developments leading to the outbreak of the accidents at the Fukushima Daiichi Nuclear Power Plant and on debates that have since evolved in Japan. Thus, this presentation here could be termed a summarization of articles that have been carried in Japanese newspapers and magazines. It admittedly includes such information whose authenticity was not fully confirmed. The judgments and views expressed in this article represent the common ground shared by vernacular newspapers and magazines. As was the case with the previous issue of this journal, the judgments and views that represent the majority opinion in Japan are carried in this issue without modification. (K.J., July 11, 2011)
