A European experiment gets a new record of fusion energy and pave the way for this new energy source

By means of deuterium fusion fusion mixture, the scheduled for the ITER nuclear fusion project conceived to obtain a new source of energy, an international team of scientists has reached the fusion energy record: 59 megajulios who have maintained during Five seconds, as they have announced their responsible Wednesday. During this experiment, a fusion power (energy per second) was reached on average of about 11 megawatts. "If we can maintain the merger for five seconds, we can do it for five minutes and then for five hours as we expand our operations in future machines," explained Tony Donn, General Director of Eurofusion, the consortium financed by the European Union that is Behind this experiment.

With this new advance the previous fusion energy record has doubled, established in 1997 with 21.7 megajulios and a fusion power of four megawatts.

According to those responsible for the experiment, its results configure the theoretical predictions and Allanan the path of the ITER project as "are the clearest demonstration in 25 years of the potential of fusion energy to provide a safe and sustainable energy with low carbon dioxide emissions ".

The fusion energy is based on the process that feeds the stars. The merger is a nuclear reaction in which two light nuclei - such as the isotopes of deuterium hydrogen and tritium-are united to form another heavier, releasing huge amounts of energy. The objective is to generate electricity unlimitedly and environmentally safely using small amounts of fuel.

The international team, of which they are part of Spanish researchers, carried out the experiments at the Joint European Torus (Jet), in Oxford (United Kingdom). It is the highest melting installation by magnetic confinement that is currently operational, and the only one in which the same combination of deuterium and tritium needed in the melting reactors can be used. It is a test bench, because it is a developing energy, but it is built with materials similar to those that will be used in ITER.

The technique based on this magnetic confinement requires heating those nuclei at temperatures about 10 times greater than that of the center of the Sun (which is one 15 million degrees Celsius) and thermally isolate them from the atmosphere around by an intense magnetic field (about 100,000 Times the earth magnetic field).

The matter at these extreme temperatures becomes a highly ionized gas called plasma. A commercial fusion center as those expected to be launched in the future would use that energy produced by the fusion reactions to generate electricity.

The Director General of the ITER, Bernand Bigot, considers that the results "suppose a great confidence in which we are on the right track to demonstrate the feasibility of fusion energy." As he has explained through a statement, "A sustained pulse of deuterium-tritium fusion at this level of power, almost on an industrial scale, is a rupture confirmation for all those who participate in the global search for merger."

The EUROFUSION consortium integrates 4,800 experts, students and technical staff from 28 countries. Approximately 300 are assigned to Spanish centers. The Center for Energy, Environmental and Technological Research (CIEMAT), the National Supercomputing Center of Barcelona and University of Seville are some of the Spanish scientific agencies involved in the research of nuclear fusion, an energy source in which there are large expectations and the EU considers it a safe, efficient and low emission medium to deal with the world energy crisis.

"It is an excellent news, a real experimental validation that we are on the right path for the development of the merger as a source of energy and in addition to a tremendous satisfaction for CIEMAT for the important contribution of our researchers to this milestone," he said by His part Carlos Alejandre, General Director of CIEMAT and ancient Deputy Director of ITER.

The next step will be to carry out a new phase of experiments in the ITER and in the European Demo Central EU demo that is being designed to put electricity in the network.

The head of the Fusion Science Department in Eurofusion, Volker Naulin, considers that these results "support the prompt decision to build a European Demo power plant, since the merger is necessary for long-term decabonization, provision energetic".
