World’s Largest Fusion Project Is in Big Trouble, New Documents Reveal

The International Thermonuclear Experimental Reactor (ITER) is already billions of dollars over budget and decades behind schedule. Not even its leaders can say how much more money and time it will take to complete

“……………………………….. 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.

………………. Since the 1950s fusion machines have grown bigger and more powerful, but none has ever gotten anywhere near what would be needed to put this panacea energy source on the electric grid. ITER is the biggest, most powerful fusion device ever devised, and its designers have intended it to be the machine that will finally show that fusion power plants can really be built.

The ITER project formally began in 2006, when its international partners agreed to fund an estimated €5 billion (then $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 €20 billion ($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Documents recently obtained via a lawsuit, however, imply that these figures are woefully outdated: ITER is not just facing several years’ worth of additional delays but also a growing internal recognition that the project’s remaining technical challenges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.

The problems leading to these latest projected delays were several years in the making. The ITER Organization was extremely slow to let on that anything was wrong, however. As late as early July 2022, ITER’s website announced that the machine was expected to turn on as scheduled in December 2025. Afterward that date bore an asterisk clarifying that it would be revised. Now the date has disappeared from the website altogether.

ITER leaders seldom let slip that anything was awry either…………………………………………………………….

In response to this stonewalling, earlier this year I initiated a lawsuit under the U.S. Freedom of Information Act seeking to reveal the extent of ITER’s expected schedule and cost troubles. So far, the lawsuit has been partially successful. It has extracted partially redacted documents revealing that in November 2021 ITER’s internal estimates showed the project already facing about 17 months of delays. By the time of the June 2022 ITER Council meeting, the number had doubled to roughly 35 months of delays—enough to easily add billions of dollars to ITER’s already bloated budget. But this timeline didn’t reflect other events bound to introduce even more delays……………………………………………….

With each passing decade, this record-breaking monument to big international science looks less and less like a cathedral—and more like a mausoleum.  https://www.scientificamerican.com/article/worlds-largest-fusion-project-is-in-big-trouble-new-documents-reveal/
