Mai Suzuki from Greenpeace Japan, removes sediment samples from the ROV grabber (Remote Operated Vehicle), at Lake Biwa. Greenpeace has been surveying lake Biwa to conduct baseline sampling. The lake is located as close as 30 km from the Takahama nuclear plant owned by Kansai Electric. In the event of a severe accident Lake Biwa would be at risk of major radioactive contamination. The lake provides the drinking water for 14,5 million people in Shiga Prefecture, the city of Kyoto and the wider Kansai region. The citizens of Shiga recently won a historic legal action that forced the immediate shutdown of Takahama reactor #3, Kansai electric is determined to overturn the legal action on appeal and restart both Takahama 3 and 4 reactor.
