The JET project : Progress toward a tokamak thermonuclear reactorFunded under: FP2-FUSION 10C
The first ever production of controlled thermonuclear energy, using a mixture of deuterium and tritium plasma, was achieved with the JET tokamak experiment on the 9th November 1991. A fusion power of 1.7 MW was obtained in a pulse 2 s long. JET plasmas have already approached equivalent conditions to those needed in a thermonuclear reactor, although only transiently, due to the high influx of impurities from the vessel walls. This problem, the main threat to the development of a fusion reactor, will be addressed in the next phase of JET development (1992-96) using a new pumped divertor magnetic configuration. In turn, the expected experimental results will provide a major contribution to the engineering design of the Next Step device, ITER, a prototype thermonuclear reactor aimed at producing fusion power in excess of 1000 MW. In this report the objectives of the JET project are outlined together with details of its operation and achievements. The first JET thermonuclear experiment is also described and possible future developments are discussed.
