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.

An experiment of Alfvén wave excitation and heating of a field-reversed configuration (FRC) plasma is presented. A low frequency magnetic pulse is applied to the FRC plasma by an azimuthally symmetrical antenna. After the pulse applied, an obvious increase of the plasma energy and the propagation of the magnetic wave are simultaneously observed. The excited wave propagates along the steady magnetic field line with the radially distributed phase velocity. The phase velocity outside the separatrix agrees the dispersion relation of the shear Alfvén wave. On the other hand, it is close to the acoustic speed, inside the separatrix. It is also observed that there is a generation of a non-oscillating toroidal magnetic field, which is possible to cause the heating of the FRC plasma.
