Facts, perspectives and hopes on the announcement of the nuclear discovery of central England. The article by Mauro Giansante
It is not true that nuclear power is only synonymous with harmful energy. The discovery of the Jet laboratory in Oxfordshire, central England, demonstrates that there can be real progress in fusion by generating low-carbon heat.
The news, writes the Guardian , is above all important because it comes after years of research and sets a new merger record after that of 1997. At that time, in fact, 21.7 megajoules were generated again in the Joint European Torus. What was recorded and announced on Wednesday, however, is more than double: 59 megajoules of heat. "An important milestone", with results that "have brought us a huge step towards conquering one of the greatest scientific and engineering challenges of all," said Professor Ian Chapman, Chief Executive Officer of the Energy Authority. nuclear power station of the United Kingdom. "It is clear that we need to make significant changes to address the effects of climate change and fusion offers so much potential," he added.
The experiments at JET focused on the feasibility of fusion with a fuel based on two isotopes of hydrogen, deuterium and tritium, which combined form helium gas. The latest findings suggest it is and provide crucial confirmation for Iter, a larger merger project under construction in southern France. Iter is expected to start burning deuterium-tritium fuel in 2035 and eventually generate more heat than is needed to keep its plasma at a high temperature. The plan, the Guardian writes, is that the next step will lead to a European demonstration power plant that produces more electricity than it uses and is connected to the grid.
“It's been a while since they produced a record like this and it's an important milestone on the way to proving that fusion is a viable and sustainable energy source for the future. Five seconds doesn't seem like a lot, but if you can burn it for five seconds, you could presumably keep it stable and keep it running for many minutes, hours, or days, which is what you'll need for a proper fusion power plant. It's proof of that concept they've achieved, ”said Mark Wenman of Imperial College.
"Now it is up to the engineers to translate this into carbon-free electricity and mitigate the problem of climate change," added Ian Fells of Newcastle University. JET is likely to be phased out after 2023 with ITER starting plasma experiments in 2025 or shortly thereafter because, writes the BBC , JET cannot actually function anymore. Its copper electromagnets get too hot. Internally cooled superconducting magnets will be used for ITER.
In short, that's not all. We await new records that will help counter global warming.
