Japan’s Fukushima Daiichi, which was destroyed after the March 11 earthquake and subsequently caused one of the worst nuclear disasters of all time, was long ranked as world’s most dangerous plant. The rankings were tracked by Fukushima’s operator Tokyo Electric Power, and in the U.S., the plant would have required more scrutiny from the Nuclear Regulatory Committee. "After the Fukushima accident, we need to reconsider the cost of nuclear power," Tatsujiro Suzuki, vice chairman of Japan's Atomic Energy Commission, told Reuters. As part of a bid to win back trust, the utility promised to repair a “safety culture” that it said failed in the disaster, and safety experts have been tapped to audit the nuclear power plant operators and regulators.
