The internal components of the fire-stroke cooling tower at the Zaporizhzhia Nuclear Power Plant (ZNPP) were seriously damaged, International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi said on Tuesday.
Grossi made the statement after a staff member of the nuclear power plant took pictures of the damage situation in the cooling tower from the water nozzle distribution level, about 10 meters high from ground.
The IAEA said on the same day that its team at the ZNPP reviewed the evidence provided to them, with Grossi saying that the evidence had strengthened the agency's conclusion that the fire in the cooling tower did not start from the bottom.
The IAEA team had also requested access to another cooling tower at the nuclear power plant to view its internal structure, but due to air raid sirens, they were escorted back to a safe location.
According to Russia's State Atomic Energy Corporation Rosatom, the cooling tower of the ZNPP was attacked by the Ukrainian forces, resulting in the tower catching fire on Sunday evening local time.
However, the Ukrainian side said on Sunday that Russia set fire to the nuclear power plant, and Russia should be held accountable for this.
Currently, the radiation levels at the nuclear power plant remain within normal limits.
The ZNPP is the largest nuclear power plant in Europe and includes six power units with a total capacity of six gigawatts.
