A NEW CONCEPT FOR FUSION REACTOR DEVICE

Zhang Chunyuan

Open publisher page 0 citations

Abstract

A new advanced concept for fusion reactor device is suggested. Combining the merits of linear and toroidal configurations as well as the fast and slow process concepts, we consider a fusion reactor consisting of two axisymme-tric tandem mirror-like sections and two heliac stellarator U-bends.Start-up, transition and operating phases are studied. The D-D reactor parameters and stabilities are discussed. The RF and energetic components are only needed for start-up; their production would constitute only a temporary energy drain on the overall reactor economics of such a system. Besides, the plugs are needed only at the start-up phase. This also greatly relax the technical requirerrtents of engineering.
