Chernobyl containment structure compromised, IAEA reports
The protective shield over Ukraine's Chernobyl nuclear reactor has lost its primary safety functions, including containment capability, following a drone strike earlier this year, the International Atomic Energy Agency (IAEA) confirmed.
Damage assessment reveals urgent repair needs
IAEA inspectors conducted a safety evaluation last week after the structure, built to prevent radioactive leaks for a century, sustained severe damage in the attack. The strike ignited a fire in the outer cladding of the steel shell, though load-bearing components and monitoring systems remained intact.
Ukraine accused Russia of targeting the site in February, a claim Moscow denied. The IAEA called repairs "essential" to halt further deterioration and ensure long-term nuclear safety.
Expert downplays immediate risk but warns of dust hazards
Environmental scientist Jim Smith, who has studied Chernobyl's aftermath, told the BBC the situation was "not something to panic about." The greatest concern, he said, was the potential release of radioactive dust, though he noted the risk was low due to existing containment measures.
The original concrete sarcophagus, built by the Soviet Union after the 1986 disaster, was designed to last 30 years. The newer protective shield was installed to prevent leaks for the next century, but its effectiveness has now been compromised.
Broader nuclear safety concerns in Ukraine
Since early December, the IAEA has been assessing Ukraine's energy infrastructure amid ongoing Russian airstrikes. Overnight attacks targeted Kremenchuk, a central industrial hub, while inspectors also examined electrical substations critical for nuclear plant operations.
"They are absolutely indispensable for providing the electricity all nuclear power plants need for reactor cooling and other safety systems," IAEA Director General Rafael Grossi said.

The substations also supply power to households and industries, underscoring their dual role in safety and civilian infrastructure.
Historical context of the Chernobyl disaster
The 1986 explosion at Chernobyl released radioactive material across Europe, prompting a public health emergency. The Soviet Union's initial sarcophagus was later reinforced with the protective shield to mitigate long-term risks.
