Dr Bernard Bigot, Director General of ITER, said:
“A sustained pulse of deuterium-tritium fusion at this power level – nearly industrial scale – delivers a resounding confirmation to all of those involved in the global fusion quest. For the ITER Project, the JET results are a strong confidence builder that we are on the right track as we move forward toward demonstrating full fusion power.”
Tony Donné, EUROfusion Programme Manager (CEO), said:
“This achievement is the result of years-long preparation by the EUROfusion team of researchers across Europe. The record, and more importantly the things we’ve learned about fusion under these conditions and how it fully confirms our predictions, show that we are on the right path to a future world of fusion energy. If we can maintain fusion for five seconds, we can do it for five minutes and then five hours as we scale up our operations in future machines.
“This is a big moment for every one of us and the entire fusion community. Crucially, the operational experience we’ve gained under realistic conditions gives us great confidence for the next stage of experiments at ITER and Europe’s demonstration power plant EU DEMO, which is being designed to put electricity on the grid.”
Ian Chapman, UKAEA’s CEO, added:
“These landmark results have taken us a huge step closer to conquering one of the biggest scientific and engineering challenges of them all. It is reward for over 20 years of research and experiments with our partners from across Europe.
“It’s clear we must make significant changes to address the effects of climate change, and fusion offers so much potential. We’re building the knowledge and developing the new technology required to deliver a low-carbon, sustainable source of baseload energy that helps protect the planet for future generations. Our world needs fusion energy.”
Volker Naulin, Head of the Fusion Science Department at EUROfusion, said:
“As EUROfusion we designed this experimental campaign at JET to optimally prepare for the start of ITER by investigating the energetic processes that will come into play there and to prepare the next generation of fusion researchers. The experiments confirmed our predictions, motivating us in doing our best to ensure a timely success of ITER operation. The results are support for an early decision for a European DEMO power plant, as fusion is needed for long term decarbonisation of our energy supply.”
