Zaporizhzhia ‘extremely fragile’ relying on single off-site power line, IAEA warns
Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

Macroscopic behavior of a high-beta and supersonic plasma flow is investigated in the HITOP device. It is found that a cylindrical plasma begins to rotate eccentrically around the center axis in a divergent magnetic mirror. The eccentric radius increases with the increase in the mirror ratio and the beta value of the plasma. The rotating frequency changes with the radial electric field in the plasma, which is controlled by end-plate biasing technique. The rotation direction and its velocity are consistent with E × B drift motion. This behavior seems to be a flute/ballooning mode driven by static and dynamic pressure gradient in a bad curvature region of the divergent field line.
