All Japan news’s government said on Monday that it will invest around $470 million (Y47 million) from reserve funds to stem radioactive water leaks at Fukushima, including freezing the ground underneath the stricken nuclear plant.
According to the politicians’ plan, a special refrigerant will be pumped trough pipes located underground, while the radioactive water will be decontaminated, Chief Cabinet Secretary Yoshihide Suga said. The scientists who will pump the refrigerant want to make a “frozen wall” that will stop the groundwater to spread into the soil.
“We estimate some Y47 billion will be needed for the project,” Suga said, according to the international press.
The contaminated water has reached the Pacific, as the underground water has been mixing with contaminated water that has already leaked into the soil. This groundwater has then made its way into the ocean, taking its mildly radioactive load with it.
The government will also finance a project to upgrade nuclear decontamination systems at Fukushima.
A long series of recent breakdowns have revealed grave vulnerabilities at the Fukushima Daiichi power plant that was hit by a violent earthquake and tsunami in 2011.
Fukushima operator Tokyo Electric Power (TEPCO) has since struggled to deal with the huge amounts of water used to cool reactors that went into meltdown after being struck two years ago.
