FILE - In this Dec. 3, 1999 file photo, engineer operators of Ukraine's Chernobyl nuclear power plant, the site of the 1986 world's worst nuclear accident, carry out their routine work inside the only operating third reactor. Twenty-five years ago, the Chernobyl Nuclear Power Plant exploded in Ukraine, spreading radioactive material across much of the Northern Hemisphere. (Efrem Lukatsky, File)

Entergy Corporation has filed a lawsuit to keep Vermont Yankee nuclear power plant open past 2012. The New Orleans-based company has federal approval to keep the plant running until 2032, but it so far has been unable to secure state approval. (Toby Talbot)

The turbines which will generate electricity at the Olkiluoto 3 nuclear power plant currently being built on Finland's west coast near Rauma, about 220 km (136 miles) northeast of Helsinki, are seen in this general view, in this file picture taken September 28, 2010. Before Fukushima, more than 300 nuclear reactors were planned or proposed worldwide, the vast majority of them in fast-growing developing economies. While parts of the developed world might now freeze or even reduce their reliance on nuclear, emerging markets such as China, India, the Middle East and Eastern Europe will continue their nuclear drive.

The Akademik Lomonosov, a floating nuclear power station, is launched at Baltiyskiy shipyard in St. Petersburg, in this handout picture taken March 25, 2011. Before Fukushima, more than 300 nuclear reactors were planned or proposed worldwide, the vast majority of them in fast-growing developing economies. While parts of the developed world might now freeze or even reduce their reliance on nuclear, emerging markets such as China, India, the Middle East and Eastern Europe will continue their nuclear drive. Russia is building the world's first offshore atomic plant, and boldly pressing ahead with its global marketing despite. increased safety fears and costs amid the fallout over Japan's ongoing nuclear emergency.
