The world's largest magnetic confinement fusion device, the Joint European Torus (JET), goes back to work following a 22-month period where the device was out of action whilst being upgraded and commissioned. Thanks to this device the European scientists are about to embark on the first round of experiments of fusion power as a safe, clean, and virtually limitless energy source for future generations.

The Joint European Torus (JET), the world's largest magnetic confinement fusion device, goes back to work. European scientists are about to embark on the first round of experiments following a 22-month period where the device was out of action whilst being upgraded and commissioned.

The JET project forms part of the preparatory stages leading to preparation for International Thermonuclear Experimental Reactor (ITER) operation, funded in part by the European Commission as part of the Seventh Framework Programme (FP7). Additionally, the research is coordinated under the European Fusion Development Agreement (EFDA), signed by all 27 Member States as well as Switzerland.

JET which is kept at the Culham Centre for Fusion Energy in the United Kingdom, is the only machine capable of operating with the deuterium-tritium fuel mixture that will be used in ITER and commercial fusion power stations. For that reason, JET will be the first fusion machine to test materials that will be used as part of ITER, whose construction site is already in progress.

JET will improve the study of fusion power, which is the attempt to mirror the process of energy release when light atomic nuclei fuse together to form heavier atoms. JET's researchers are investigating the potential of fusion power as a safe, virtually limitless and clean energy because the fusion power process produces no greenhouse gases or long-lived radioactive waste according to them.
