Japan will dispose of the second batch of processed radioactive water on Thursday (5/10).
The release came after Russia said on Wednesday (4/10) that Japan had not provided complete information regarding the water release, despite repeated requests from Moscow and Beijing.
Japan began dumping treated water from its nuclear power plants into the ocean in late August, prompting strong criticism from China. In response, China imposed a complete ban on imports of aquatic products from Japan.
Japan says the water is safe because it has been pre-treated to remove the most radioactive elements, except tritium, a radionuclide that is difficult to separate from water. The water is then diluted to levels that meet international criteria before being discharged. Japan says that Russia and China’s criticism is not supported by scientific evidence.
A devastating earthquake and tsunami in 2011 triggered a nuclear crisis in Fukushima, making it the world’s worst nuclear disaster since Chernobyl, which took place 25 years earlier and occurred in what was then Soviet Ukraine. (rd/rs)
