The water has been used to cool three melted reactors since the nuclear disaster in March 2011. According to BBC, "most of the radioactive isotopes have been removed using a complex filtration process. But one isotope, tritium, cannot be removed so the water has been stored in huge tanks which will fill up by 2022."
Environment Minister Yoshiaki Harada supports the plan of dumping the water into the Pacific, where it would be diluted, posing a low risk to human and animal health. The Japanese Government, however, said that no decision was made yet.
Fishermen’s groups are opposed to the plan, as it affects their activities and reputation directly. The South Korea government also has its concerns due to the geographical proximity and the possible impacts the dumping may cause to the health and safety of people and ocean.

Eisbohrkern enthält intaktes Klimaarchiv der vergangenen 12.000 Jahre
Ein einzigartiges, intaktes Archiv vergangener klimatischer Bedingungen enthält ein Eisbohrkern, der vom Dôme du Goûter des Mont-Blanc-Massivs stammt. Einem internationalen Forschungsteam mit Wissenschaftlern der Universität Heidelberg ist es gelungen, den bereits 1999 geborgenen Kern umfassend zu datieren
