**World's Largest Fusion Project Is In Big Trouble, New Documents Reveal**

An anonymous reader quotes a report from Scientific American: It could be a new world record, although no one involved wants to talk about it. In the south of France, a collaboration among 35 countries has been birthing one of the largest and most ambitious scientific experiments ever conceived: the giant fusion power machine known as the International Thermonuclear Experimental Reactor (ITER). But the only record ITER seems certain to set doesn't involve "burning" plasma at temperatures 10 times higher than that of the sun's core, keeping this "artificial star" ablaze and generating net energy for seconds at a time or any of fusion energy's other spectacular and myriad prerequisites. Instead ITER is on the verge of a record-setting disaster as accumulated schedule slips and budget overruns threaten to make it the most delayed -- and most cost-inflated -- science project in history.

The ITER project formally began in 2006, when its international partners agreed to fund an estimated \[$6.3 billion\], 10-year plan that would have seen ITER come online in 2016. The most recent official cost estimate stands at more than \[$22 billion\], with ITER nominally turning on scarcely two years from now. Documents recently obtained via a lawsuit, however, imply that these figures are woefully outdated: ITER is not just facing several years' worth of additional delays but also a growing internal recognition that the project's remaining technical challenges are poised to send budgets spiraling even further out of control and successful operation ever further into the future.

The documents, drafted a year ago for a private meeting of the ITER Council, ITER's governing body, show that at the time, the project was bracing for a three-year delay -- a doubling of internal estimates prepared just six months earlier. And in the year since those documents were written, the already grim news out of ITER has unfortunately only gotten worse. Yet no one within the ITER Organization has been able to provide estimates of the additional delays, much less the extra expenses expected to result from them. Nor has anyone at the U.S. Department of Energy, which is in charge of the nation's contributions to ITER, been able to do so. When contacted for this story, DOE officials did not respond to any questions by the time of publication.
