Fukushima Dai-ichi nuclear power plant chief Akira Ono leaves after speaking to the media inside Seismic Isolated Building, or command center, at the Fukushima Dai-ichi nuclear power plant in Okuma, Fukushima, northeastern Japan, Thursday, Nov. 7, 2013. The plant, run by Tokyo Electric Power Co., has recently had a series of mishaps, including leaks of radioactive water from storage tanks. The incidents, many of them caused by human error, have added to concerns about TEPCO's ability to safely close down the plant, which suffered multiple meltdowns after being hit by a March 2011 earthquake and tsunami.
