Another toxic water leak was discovered at Fukushima nuclear power plant, according to Tokyo Electric Power (TEPCO) – the operator of the plant.
This time, the radioactive water leaked from a different storage tank to the one where a similar leak was found in August, TEPCO said. The operator does not know the exact amount of water that leaked from the 450-ton tank.
TEPCO said it had determined that contaminated water had accumulated within barriers around the tank, and may have flowed past the barriers, according to the international press.
The barriers were installed to block water from spreading when a leak occurs in the storage tanks at the plant.
Around 300 tons of radioactive water had leaked from a separate tank in August, a part of it believed to have reached the Pacific Ocean.
One month ago, Japan’s government said 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 in order to make a “frozen wall” that will stop the groundwater to spread into the soil.
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.
TEPCO has since struggled to deal with the huge amounts of toxic water used to cool reactors that went into meltdown after being struck two years ago.
