Fukushima operator 'knew of need to protect against tsunami but did not act'

Fukushima operator 'knew of need to protect against tsunami but did not act' | 18 June 2015 | The operator of Japan's ruined Fukushima Daiichi nuclear power plant was aware of the need to improve the facility’s defences against tsunami more than two years before the March 2011 disaster but failed to take action, according to an internal company document. The revelation casts doubt on claims by Tokyo Electric Power (Tepco) that it had done everything possible to protect the plant, which suffered a triple meltdown after being struck by a towering tsunami. The utility disclosed the document this week during a lawsuit brought by more than 40 Tepco shareholders who are demanding damages totalling 5.5 trillion yen from company executives.
