Chuck Darwin<p>Is the dream of nuclear fusion dead? </p><p>Why the international experimental reactor is in ‘big trouble’ </p><p>It was a project that promised the sun. </p><p>Researchers would use the world’s most advanced technology to design a machine that could generate atomic fusion, <br>the process that drives the stars <br>– and so create a source of cheap, non-polluting power.</p><p>That was initially the aim of the ⭐️International Thermonuclear Experimental Reactor ⭐️ <br>( <a href="https://c.im/tags/Iter" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Iter</span></a> ) which 35 countries <br>– including European states, China, Russia and the US <br>– agreed to build at Saint-Paul-lez-Durance in southern France <br>at a starting cost of $6bn. </p><p>Work began in 2010, with a commitment that there would be energy-producing reactions by 2020.</p><p>Then cost overruns, Covid, corrosion of key parts, last-minute redesigns and confrontations with nuclear safety officials triggered delays that <br> mean <a href="https://c.im/tags/Iter" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Iter</span></a> is not going to be ready for another decade, <br>it has just been announced. </p><p>Worse, energy-producing fusion reactions will not be generated until 2039, while Iter’s budget <br>– which has already soared to $20bn<br>– will increase by a further $5bn.</p><p>Other estimates suggest the final price tag could rise well above this figure <br>and make Iter <br>“the most delayed and most cost-inflated science project in history”, <br>the journal Scientific American has warned. </p><p>For its part, the journal Science has stated simply that Iter is now in “big trouble”, <br>while Nature has noted that the project has been “plagued by a string of hold-ups, cost overruns and management issues”.</p><p>Dozens of private companies now threaten to create fusion reactors on a shorter timescale, warn scientists. </p><p>These include <a href="https://c.im/tags/Tokamak" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Tokamak</span></a> <a href="https://c.im/tags/Energy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Energy</span></a> in Oxford <br>and <a href="https://c.im/tags/Commonwealth" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Commonwealth</span></a> <a href="https://c.im/tags/Fusion" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Fusion</span></a> <a href="https://c.im/tags/Systems" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Systems</span></a> in the US.</p><p>“The trouble is that Iter has been going on for such a long time, and suffered so many delays, <br>that the rest of the world has moved on,” said fusion expert Robbie Scott of the UK Science and Technology Facilities Council. </p><p>“A host of new technologies have emerged since Iter was planned.
