The International Atomic Energy Agency (IAEA) has reported that the protective casing designed to shield against radioactive emissions at Ukraine's Chernobyl disaster site is not functioning properly after being damaged by a drone strike in February.
According to the agency, this failure means the structure has lost its ability to contain the radioactive material remaining from the 1986 explosion.
The Chernobyl Nuclear Power Plant, while part of the Soviet Union in 1986, suffered one of the most severe explosions in history, resulting in the spread of radioactive contamination across Europe.
The plant's last operational reactor was shut down in 2000. To deal with the disaster, the Soviets constructed a concrete sarcophagus over the reactor, which had a lifespan of only 30 years.
The current protective structure, known as the New Safe Confinement (NSC), was built over a decade to control radioactive emissions during the removal of the old sarcophagus, the underlying destroyed building, and nuclear fuel.
The NSC, which is 110 meters high and 260 meters wide, was completed in 2019 at a cost of 1.5 billion Euros ($1.75 billion).
In a statement released on Friday, the IAEA said that following an inspection of the steel-clad structure last week, it was determined that it "is no longer fully capable of performing its original safety functions."
The IAEA further noted that the damage was caused by a drone strike in February. Ukraine alleges that Russia was responsible for the drone attack; the war between the two nations is now in its fourth year.
IAEA Director General Rafael Grossi stated, “The confinement structure has lost its capacity to block radioactive emissions.
However, the load-bearing structure or the monitoring systems have not suffered any permanent damage.” Grossi added that some repairs have been made to the damaged section, but a full renovation is needed to ensure long-term nuclear safety.
Since the war began, both Russia and Ukraine have accused each other of attacking the facility, thereby creating the risk of a catastrophic nuclear disaster.
The United Nations reported that on February 14, Ukrainian authorities informed them that a high-explosive drone had struck Reactor No. 4 of the Chernobyl Nuclear Power Plant.
This caused a fire and damaged the protective casing around the reactor that was destroyed in the 1986 explosion.
Ukraine claimed the drone was Russian, but Moscow denied the accusation, saying it did not attack the facility. The UN noted that in February, radiation levels were normal and stable, and there were no reports of radiation leaks.
Russia occupied the plant and surrounding area for over a month, starting in the first week of its full-scale invasion of Ukraine in February 2022, as its forces initially sought to advance toward the Ukrainian capital, Kyiv.
The IAEA inspected the damaged Chernobyl structure at the same time it was assessing damage to electrical substations across various parts of Ukraine due to the ongoing conflict.
