TOKYO: The operator of Japan's crippled Fukushima nuclear power plant has found that a coolant solution, used to create an ice wall halting the seepage of groundwater into reactor buildings, has leaked from two storage tanks.Still, it underscores the unpredictable challenges in the clean-up of the site, nearly 11 year after an earthquake and tsunami ravaged Japan's northeastern coast, causing the world's worst nuclear disaster since Chernobyl, Ukraine, in 1986.
On Sunday, Tepco spokesperson Tsuyoshi Shiraishi said about four tonnes of a calcium chloride solution used to maintain the ice wall had leaked in what was the eighth such leakage.The last leak in December 2019 saw 16 tonnes spilled, likely due to metal fatigue resulting from vibrations caused by construction vehicles, Shiraishi said.
Separately, a group of six men and women is set to file on Jan 27 a lawsuit against Tepco claiming they developed thyroid cancer due to exposure to radiation from the Fukushima disaster, the Mainichi newspaper reported.
