“The last remaining back up 330 kilovolt (kV) power line at the Zaporizhzhya Nuclear Power Plant (ZNPP), damaged since 1 March, remains disconnected and under repair, again highlighting the fragility of nuclear safety and security at Europe’s largest nuclear power plant (NPP),” informed the IAEA Director General.
For three weeks, the ZNPP received electricity from only one main external power transmission line of 750 kV, any damage to which would lead to a complete loss of off-site power to the plant.
“Nuclear safety at the ZNPP remains in a precarious state. If this disconnection from the main power line and repair work is performed while the 330 kV line is not available it will cause a complete loss of power and will make the plant reliant on diesel generators – its last line of defense – for the seventh time,” said Director General Rafael Grossi.
