Super Tuesday demonstrated the rancour rife in Republican ranks, as the four remaining major candidates slug it out to see how far to the right of President Barack Obama they can go. While attacking him daily for the high cost of gasoline, both sides are travelling down the same perilous road in their support of nuclear power. This is mind-boggling, on the first anniversary of the Fukushima nuclear disaster, with the chair of the U.S. Nuclear Regulatory Commission warning that lessons from Fukushima have not been implemented in this country. Nevertheless, Democrats and Republicans agree on one thing: They're going to force nuclear power on the public, despite the astronomically high risks, both financial and environmental.

New details are emerging that indicate the Fukushima nuclear disaster in Japan is far worse than previously known, with three of the four affected reactors experiencing full meltdowns. Meanwhile, in the U.S., massive flooding along the Missouri River has put Nebraska's two nuclear plants, both near Omaha, on alert. The Cooper Nuclear Station declared a low-level emergency and will have to close down if the river rises another 3 inches. The Fort Calhoun nuclear power plant has been shut down since April 9, in part due to flooding. At Prairie Island, Minn., extreme heat caused the nuclear plant's two emergency diesel generators to fail. Emergency-generator failure was one of the key problems that led to the meltdowns at Fukushima.
