An experimental nuclear fusion reactor that generates energy by discharging plasma Wendelstein 7-XIt was redesigned, and thought experiments showed that optimizing the implemented system was “not a bug”.

Wendelstein 7-X is Germany Greifswald A fusion pilot reactor is installed. For nuclear fusion reactors, that is, nuclear reactors that use nuclear fusion reactions, the temperature is very high-generation technology, and Wendelstein 7-X is an experimental reactor that allows experiments with this method of magnetic confinement.

The magnetic field confinement method is a method in which the coil is wound circularly to flow an electric current and the plasma is confined to the generated magnetic field. Spiral type “if” Tokamak type It is divided into two types. The spiral type is easier to operate than the tokamak type when stationary, but it has the problem that it is difficult to construct because of the large plasma loss. Wendelstein 7-X is a spiral-shaped pilot reactor with the main goal of “reducing plasma loss”.

Craig Bidler of the Max Planck Institute for Plasma Physics, who led the study, wondered whether Wendelstein 7-X might have been improved in capturing plasma but actually had the desired effect, and the investigation has begun.

The previous experiment A thought experiment was carried out on the basis of the generated plasma discharge data in and under the assumption that “if Wendelstein 7-X is not improved”, the plasma loss will exceed the heating power. Against this background, Mr. Biedler concluded that “the plasma loss could be reduced with an optimal Wendelstein 7-X”.

“The aim of fusion research is to develop environmentally and climate-friendly power plants,” said Weidler with the aim of raising the inclusion quality of Wendelstein 7-X plasma to the level of competing tokamak systems.
