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.

To complete basic configuration for the RF heating scenario in Central Cell of the Hanbit mirror device, a RF amplifier system with a power of 100 kW and frequency range of 1.4 – 4.0 MHz, and a high power RF matching network have been developed in KBSI. The output pulse width of the amplifier ranges from 10 msec to 100 msec and the duty cycle is 100 msec/300 sec. The developed amplifier will be used for plasma production and heating by utilizing the slot antenna and the double-half-turn antenna, respectively.
In this paper, we present the engineering design of the amplifier system and matching network, and experimental results such as power test of amplifier on dummy load, impedance matching test on the double-half-turn antenna in vacuum condition. Also, the first RF launching experiment result with the double-half-turn antenna on the target plasma which is produced by the slot antenna is presented.
