A new report from the International Atomic Energy Agency finds Japan underestimated the danger of tsunamis and failed to adequately prepare backup systems at the Fukushima Daiichi nuclear power facility. The IAEA echoed a widely held criticism that collusion between the nuclear industry and regulators resulted in a lack of oversight and inadequate safety levels at the now-stricken plant. The report comes as Japanese Prime Minister Naoto Kan has survived a no-confidence vote in the Japanese parliament.
