The threat of global warming has brought nuclear power - currently available only through fission and long out of favor - back to the forefront as a way of generating energy because it creates no so-called greenhouse gases, a cause of global warming.
Nuclear fission - with heat as a byproduct - occurs when heavy atoms such as those of uranium or plutonium are split. But the process leaves behind highly radioactive waste, and the reactors can catastrophically melt down.
Harnessing fusion as an energy source has long been a dream of physicists because it would be safer, cleaner and cheaper - using naturally abundant hydrogen as an energy source.
The major source of energy right now, the burning of fossil fuels such as coal and oil, spews greenhouse gases into the Earth's atmosphere and trap the sun's heat. Oil supplies are expected to begin running short in about 50 years.
As a replacement, fusion would produce much more energy than fission, while leaving behind small amounts of relatively harmless waste and posing no danger of a nuclear meltdown.
"This is not good news for the fight against the greenhouse effect, because we're going to put $13 billion toward a project that has a term of 30-50 years, when we're not even sure it will be effective," Greens party lawmaker Noel Mamere said on France-Info radio.
But State Department spokesman Tom Casey said the United States was pleased the sides had agreed on a site. "Now the six partners will work together to resolve the other various technical and legal questions that exist so we can move forward on this critically important energy experiment," he said.
Participants will now negotiate the construction details and sign a final agreement, hopefully by year's end.
The project is expected to create 10,000 jobs and take about eight years to build.
But fulfilling the long-term vision of the International Thermonuclear Experimental Reactor, as it is called, could take decades.
Cadarache, in the southern region of Provence, was chosen during talks in Moscow after Japan, which had sought the project, reportedly backed down, agreeing instead to a bigger role in research and operations.
If all goes well with the experimental reactor, officials hope to set up a demonstration power plant in Cadarache around 2040. Officials project that as much as 20 percent of the world's energy could come from fusion by the century's end, said Raymond L. Orbach, the U.S. Department of Energy's office of science director.
President Jacques Chirac called the decision "a great success for
"The international community will now be able to take on an unprecedented scientific and technological challenge, which opens great hopes for providing humanity with an energy that has no impact on the environment and is practically inexhaustible," he said.
The EU argued that Cadarache, one of the biggest civil nuclear research centers in

"We made it clear from the very beginning that our technical preference was for the Japanese site, but that we would support what was finally (agreed) upon," he said.
"We are all dealing with the question of how to address a sustainable and also environmentally friendly energy source for the future, and fusion is extremely promising," EU Research Commissioner Janez Potocnik said.

The EU also will support a Japanese candidate for the post of the ITER director general and back the construction later of a demonstration reactor in
