‘Very dangerous’ situation at Russian-held Zaporizhzhia nuclear plant, says IAEA chief

The head of the UN nuclear watchdog, Rafael Grossi, has described the situation at Ukraine’s Russian-occupied Zaporizhzhia nuclear plant in southeastern Ukraine as “very dangerous” and very unstable.

The nuclear facility has lost its external power supply six times since Russia’s invasion of Ukraine more than a year ago, forcing emergency diesel generators to kick in to cool its reactors.

Grossi, who heads the International Atomic Energy Agency (IAEA), said the water level in a nearby reservoir controlled by Russian forces was another potential danger. Water supplied by the reservoir is used to cool the reactors.

He told Reuters: 

If the reservoir level goes down beyond a certain level, then you don’t have water to cool down the reactors, and we have seen especially in January that the levels of the water were going down significantly. They recovered somehow in the past few weeks.

He added that there had been increasing military activity in the region without giving details.

Grossi, who yesterday met with President Volodymyr Zelenskiy at the Dnipro hydroelectric power station, northeast of the Zaporizhzhia plant, said his attempt to broker a deal to protect the plant was still alive, and that he was adjusting the proposals to seek a breakthrough.

He was speaking a day before he is expected to travel to the nuclear plant, the largest in Europe.

Grossi has been pushing for a safety zone to be created at the plant to prevent a possible nuclear disaster as Moscow and Kyiv have accused each other of shelling the site of the power station. Kyiv does not want a deal that will in effect recognise or allow a Russian military presence at the plant.

Grossi added:

I am confident that it might be possible to establish some form of protection, perhaps not emphasising so much the idea of a zone, but on the protection itself: what people should do, or shouldn’t do to protect (the plant) instead of having a territorial concept.
