Japan re-entered the nuclear business today for the first time since the Fukushima Dai-ichi meltdown more than a year ago, reports Reuters. Kansai Electric Power Co fired up the No. 3 reactor at its Ohi plant, and will add its No. 4 reactor later this month. The move comes as Japan stares down a summer energy crisis, yet is intensely unpopular among the nearly 70% of Japanese who want the government to eradicate nuclear power altogether. Protesters clogged both the Ohi plant and the streets of downtown Tokyo in response.
