SNIP: Japan is to release treated radioactive water from the destroyed Fukushima nuclear plant into the sea, media reports say.

It follows years of debate over how to dispose of the liquid, which includes water used to cool the power station hit by a massive tsunami in 2011.

Environmental and fishing groups oppose the idea but many scientists say the risk it would pose is low.

The government says no final decision has been made.

The release of more than a million tonnes of water, which has been filtered to reduce radioactivity, would start in 2022 at the earliest, according to Japanese media outlets including national dailies the Nikkei and the Yomiuri Shimbun.

The water would be diluted inside the plant before release so it is 40 times less concentrated, the Yomiuri Shimbun said, with the whole process taking 30 years.

There has been growing urgency over what to do with the water as space to store the liquid – which includes groundwater and rain that seeps daily into the plant – is running out.

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.

Environmental groups have long expressed their opposition to releasing the water into the ocean. And fishing groups have argued against it, saying consumers will refuse to buy produce from the region.
