Radioactive Fukushima groundwater rises above barrier: Report
TOKYO (REUTERS) - Radioactive groundwater at the crippled Fukushima nuclear plant has risen to levels above a barrier being built to contain it, highlighting the risk of an increasing amount of contaminated water reaching the sea, Japanese media reported on Saturday.
The Asahi newspaper, citing data from a Friday meeting of a task force working on the Fukushima clean-up at Japan's nuclear regulator, estimated that the contaminated water could swell to the ground surface within three weeks.
The latest revelation underscores the hurdles facing Tokyo Electric Power (Tepco) more than two years after a massive earthquake and tsunami destroyed the Fukushima plant, triggering the world's worst nuclear disaster since Chernobyl.
One of Tepco's biggest challenges is trying to contain radioactive water that cools the reactors as it mixes with some 400 tonnes of fresh groundwater pouring into the plant daily.
