IAEA Director General Rafael Mariano Grossi said: “Of the six temporary ceasefires that we have negotiated since late last year to help protect nuclear safety … this was the most challenging to implement. It required several months of delicate negotiations, followed by mine clearance and repairs on high pylons across the Dnipro River. The IAEA monitored these activities on the ground to confirm they were carried out as agreed.
“Both sides worked constructively with us to enable the repairs to proceed. Despite the many military and technical challenges, this demonstrates that concrete progress remains possible, even during a large-scale war. We will continue our efforts to reduce the ever-present danger of a nuclear accident.”
The IAEA team based at the Zaporizhzhia plant monitored the repair work on the plant side of the frontline, with a separate IAEA team monitoring the repair work on the other side of the Dnipro River.
However the 750 kV Dniprovska external power line is not back in operation yet, because of damage sustained in May at an electrical substation 100 kilometres northwest of the plant, Grossi said.
“Repeated damage to the electrical infrastructure on which nuclear power plants depend continues to create serious nuclear safety and security risks. I once again call for maximum military restraint around all nuclear facilities and the power infrastructure they require,” he said.
Since the main Dniprovska line was disconnected in March, the six-unit nuclear power plant, which has been under Russian military control since early March 2022, has been relying on its sole remaining 330 kV Ferosplavna-1 backup power line.
During the war there have been a number of occasions when all external power has been lost to the plant. Last week the back-up power line was reconnected after the 19th such loss of power. As with the previous occasions, the plant had to rely on power from its emergency diesel generators for the power required by the plant, including for various safety functions.
