Drone attacks hit Zaporizhzhia nuclear plant, including a reactor building, IAEA says
Current state
On 7 April 2024 drones struck the Russian-controlled Zaporizhzhia Nuclear Power Plant, the first direct targeting of the plant since November 2022 according to the IAEA. The IAEA's director general reported at least three direct hits against the main reactor containment structures, and on 9 April another drone detonated on the roof of the plant's training centre outside the site perimeter. Russia and Ukraine blamed each other.

The IAEA said damage at unit 6 did not compromise nuclear safety but was a serious incident with potential to undermine the integrity of the reactor's containment system, and one casualty was reported. Russia's state nuclear agency said three people were wounded. The plant's six reactors had been shut down for months.
IAEA experts at the plant verified the impact of several drone attacks on 7 April, and on 9 April they heard a loud explosion at the time the plant said a drone detonated on the training centre roof. The IAEA team was denied access to several locations for security reasons. The director general later told the IAEA Board the strike did not compromise nuclear safety in a serious way.

| Claim and source passage | Original source | Assessment |
|---|---|---|
| The IAEA confirmed physical impact of drone attacks at the plant, including at one of its six reactors. “In a separate statement, the IAEA confirmed physical impact of drone attacks at the plant, including at one of its six reactors.” [2] | International Atomic Energy Agency (IAEA) (relayed) | supports: Confirmation by an international body whose team was on site; the basis for the confirmed drone status. |
| The IAEA director general confirmed at least three direct hits against the main reactor containment structures. “confirmed at least three direct hits against the ZNPP main reactor containment structures took place” [2] | IAEA Director General (relayed) | supports: Statement posted on X and reported by AP. |
| The IAEA said damage at unit 6 had not compromised nuclear safety but was a serious incident that could undermine containment integrity. “Damage at unit 6 has not compromised nuclear safety, but this is a serious incident with potential to undermine integrity of the reactor's containment system” [2] | International Atomic Energy Agency (IAEA) (relayed) | supports: Describes the limits of the damage as well as the risk. |
| On 9 April the IAEA team heard an explosion at the time the plant said a drone detonated on the training centre roof. “a loud explosion at 11:05am local time today, the same time that the ZNPP later said an incoming drone had detonated on the roof of the facility's training centre” [1] | International Atomic Energy Agency (IAEA) | supports: The IAEA corroborates the explosion and its timing, but could not access the building to assess the impact. |
| The IAEA director general did not name who was behind the attacks. “Whoever is behind them, they are playing with fire. Attacking a nuclear power plant is extremely irresponsible and dangerous, and it must stop” [1] | IAEA Director General | context: Explicitly leaves the attacker unnamed. |
| Plant officials said the site was attacked by Ukrainian military drones, including a strike on the dome of the sixth power unit. “Officials at the plant said the site was attacked Sunday by Ukrainian military drones, including a strike on the dome of the plant's sixth power unit.” [2] | Officials at the Russian-controlled plant (relayed) | supports: Statement by the occupying side; the IAEA has not confirmed who launched the drones. |
| Ukraine's UN ambassador called the strike a false flag operation by Russia. “called the drone strike a “well-planned false flag operation” by Russia” [3] | Ukraine's ambassador to the United Nations (relayed) | contradicts: Counter-accusation by a party to the conflict, unverified. |
