Fukushima Nuclear Plant Disaster in Japan and a Problem in the Role of Meteorologists
Predavatelj bo prof. dr. Hiroshi L. Tanaka, Center for Computational Science, University of Tsukuba
The Fukushima Daiichi Nuclear Power Plant released radioactive materials following the Tohoku earthquake and tsunami on 11 March 2011. After the several hydrogen-air chemical explosions of the plant, a large amount of nuclear pollutant was released to the air. The pollutant was supposed to be monitored and predicted by the primary model called SPEEDI operated by the Ministry of Education. Japan Meteorological Agency (JMA) was not responsible for the nuclear
accident, so they cannot act by law to the nuclear pollutant tracking even though they could do it perfectly. Their role is to protect the nation from weather related natural disaster. Meteorologists and researchers in university can predict but cannot release the pollutant prediction because JMA is the responsible agency in prediction. A strict one voice regulation is applied when human life is in danger by serious weather events. After all, It was unfortunate that SPEEDI did
not operate appropriately, JMA could not assist it by law, and university researchers kept quiet by the one voice regulation. People had to get real-time information about the pollutant transport from foreign agencies mostly in Europe through the Internet. There is a big argument in Japan on the role of meteorologist to or not to provide transport prediction in nuclear emergency with large uncertainty.
