Japan will release more than a million tons of treated radioactive water from the stricken Fukushima nuclear plant into the sea in a decades-long operation, reports said on Friday, despite strong opposition from local fishermen.
The release of the water, which has been filtered to reduce radioactivity, is likely to start in 2022 at the earliest, said national dailies the Nikkei, the Yomiuri, and other local media.
The decision ends years of debate over how to dispose of the liquid that includes water used to cool the nuclear power station after it was hit by a massive tsunami in 2011.
A government panel said earlier this year that releasing the water into the sea or evaporating it were both “realistic options.”
“We can’t postpone a decision on the plan to deal with the ... processed water, to prevent delays in the decommission work of the Fukushima Daiichi nuclear power plant,” Chief Cabinet Secretary Katsunobu Kato said on Friday, without commenting directly on the details of the plan or its timing.
There are around 1.23 million tons of waste water stored in tanks at the facility, according to plant operator Tokyo Electric Power Co, which also declined to comment on the reports.
Environmental activists have expressed strong opposition to the proposals, and fishermen and farmers have voiced fear that consumers will shun seafood and produce from the region.
South Korea, which bans imports of seafood from the area, has also repeatedly voiced deep concern about the environmental impact.
A decision is becoming urgent as space to store the water — which also includes groundwater and rain that seeps daily into the plant — is running out.
Most of the radioactive isotopes have been removed by an extensive filtration process — but one remains, called tritium, which cannot be removed with existing technology.
The expert panel advised in January that discarding the water into the sea was a viable option because the method is also used at working nuclear reactors.
