Dwindling water levels in the cooling pond at the Zaporizhzhia nuclear power station in Ukraine remains a potential source of concern, International Atomic Energy Agency director-general Rafael Grossi said on 2 August.

According to Grossi, the water level in the cooling pond is continuing to decrease and despite all six reactors at Zaporizhzhia remaining in a state of cold-shutdown, availability of this water is important for nuclear safety of the facility.
