Japan’s Fukushima nuclear crisis was a preventable disaster resulting from “collusion” among the government, regulators and the plant operator, an expert panel said, wrapping up an inquiry into the worst nuclear accident in 25 years.

A protest took place at the gate of a Japanese nuclear power plant as it was restarted — the first such facility to go back online since the country shut down all of its reactors for safety checks following the Fukushima nuclear disaster.

Japan moved closer today to restarting nuclear reactors for the first time since last year's earthquake and tsunami led to a nationwide shutdown after a mayor gave his support to a plan to bring two of them back online.
