Chernol protective shield stopped working, can’t confine radiation after February drone strike: IAEA | World News

The International Atomic Energy Agency (IAEA) has said that the protective shield around the Chernol nuclear disaster site in Ukraine has stopped working after being damaged in drone strikes in February.The UN Nuclear Watchdog said the radiation shield has “lost its primary safety functions, including the confinement capability.”

According to the IAEA, which conducted an inspection of the steel confinement structure last week, it found that the drone impact had degraded the structure.

The New Safe Confinement (NSC) at Chernol was built in 2019 to replace the reactor destroyed in the plant’s 1986 meltdown, which resulted in the worst nuclear disaster the world has seen so far.

But it became the scene of the world’s worst nuclear disaster in April 1986 when one of the reactors malfunctioned, releasing huge amounts of radioactive material across Europe.

Around 30 people were killed in the disaster, and the entire region has been abandoned ever since due to radioactivity.

The Soviet Union had built a concrete “sarcophagus” over the meltdown reactor to contain the spread. It was replaced with the Europe-funded protective shield in 2019, which is now damaged.

The structure, which took around nine years to complete, was designed to last 100 years.Story continues below this ad

Following the collapse of the Soviet Union in 1991 and the formation of Ukraine, the Chernol plant and the exclusion zone came under the newly formed country.

The safety of Chernol was a major concern in the initial days of the invasion of Ukraine, as the nuclear plant and the surrounding exclusion zone were captured Russia. Following the failed attempts to capture Kyiv, Russian troops withdrew from the area, including Chernol, in April 2022.

Chernol was in the spotlight again in February this year when the containment structure was hit drones. Ukrainian President Volodymyr Zelenskyy had blamed Russia for the drone attack.

The Nuclear watchdog has recommended a major renovation of the huge steel structure.

“Limited temporary repairs have been carried out on the roof, but timely and comprehensive restoration remains essential to prevent further degradation and ensure long-term nuclear safety,” IAEA Director General Rafael Mariano Grossi said.

Grossi, however, added that there had been no permanent damage to the NSC’s load-bearing structures or monitoring systems.
