Fukushima's most important lesson is this: Probability theory (that disaster is unlikely) failed us. If you have made assumptions, you are not prepared. Nuclear power plants should have multiple, reliable ways to cool reactors. Any nuclear plant that doesn't heed this lesson is inviting disaster.
Japan's government declared that the damaged reactors from the Fukushima disaster were 'stable.' Not everyone is convinced.
Experience in northern Japan illustrates that even incremental investment in nuclear power threatens human civilization. The Fukushima disaster should once and for all drive global society away from nuclear power, and toward renewable energy.
Polls show the public turning against nuclear energy after Japan's Fukushima disaster. But low coverage of protests and powerful business and political interests have complicated efforts to promote change.
More than six months after a quake triggered a devastating tsunami and nuclear crisis in Japan, there is still much left to do – and a fear that no one’s listening.
