Late Fukushima manager flagged risks of Japan's big nuclear plants

TOKYO (Reuters) - The late manager of Japan's destroyed Fukushima plant questioned the safety of large nuclear facilities, documents showed on Thursday, potentially affecting the debate over the restart of the world's biggest nuclear power station.

Masao Yoshida, who led the emergency response at Tokyo Electric Power Co's Fukushima Daiichi plant after the March 2011 nuclear disaster, told investigators five months later that facilities with six or seven reactors were difficult to operate and had inherent safety risks, according to transcripts released by the government.
