Treated water from Fukushima plant to be released into the sea
TOKYO: Japan will release more than a million tonnes of treated water from the stricken Fukushima nuclear plant into the ocean, the government said yesterday, triggering a furious regional reaction and fierce opposition from local fishing communities.
The process is not likely to begin for several years and could take decades to complete, but China quickly slammed the decision as “extremely irresponsible” and South Korea summoned the Japanese ambassador.
Japan’s government argues the release is safe because the water is processed to remove almost all radioactive elements and will be diluted.
The International Atomic Energy Agency (IAEA) has endorsed the release, which it says is similar to the disposal of wastewater at nuclear plants elsewhere.
Prime Minister Yoshihide Suga told a ministerial meeting that disposing of the water was an “inevitable task” in the decadeslong process of decommissioning the nuclear plant.
He said the release would happen only “after ensuring the safety levels of the water” and alongside measures to “prevent reputational damage”.
Around 1.25 million tonnes of water have accumulated in tanks at the nuclear plant, which was crippled after going into meltdown following the 2011 tsunami.
It includes water used to cool the plant, as well as rain and groundwater that seeps in daily.
An extensive pumping and filtration system extracts tonnes of newly contaminated water each day and filters out most radioactive elements.
But local fishing communities fear releasing the water will undermine years of work to restore confidence in their seafood.
“They told us that they wouldn’t release the water into the sea without the support of fishermen,” Kanji Tachiya, who heads a local fisheries cooperative in Fukushima, told NHK ahead of the announcement.
“We can’t back this move to break that promise and release the water into the sea unilaterally.”
Plant operator Tepco will “take thorough measures to prevent bad rumours”, said its president Tomoaki Kobayakawa.
China’s foreign ministry slammed Japan’s decision, saying it had been taken “without regard for domestic and foreign doubts and opposition”.
“This approach is extremely irresponsible and will seriously damage international public health and safety,” it said.
South Korea’s foreign ministry also called it “a risk to the maritime environment” and later announced it had summoned Japan’s ambassador.
The US State Department, however, said Japan had been “transparent about its decision, and appears to have adopted an approach in accordance with globally accepted nuclear safety standards”.
Government spokesman Katsunobu Kato said Tuesday that the water would be diluted to contain tritium at levels far below either domestic or WHO standards, with the IAEA monitoring the process.
Experts say the element is only harmful to humans in large doses and with dilution the treated water poses no scientifically detectable risk.
“There is consensus among scientists that the impact on health is minuscule,” Michiaki Kai, an expert on radiation risk assessment at Japan’s Oita University of Nursing and Health Sciences, told AFP before the decision was announced.
