Panic as Chernobyl’s $2 billion protective shield cracks open sparking fears of a deadly radiation leak

Daily Mail, By STACY LIBERATORE, US SCIENCE & TECHNOLOGY EDITOR, 18 December 2025 

The dome built over the remains of the Chernobyl disaster has been damaged, raising fears it may no longer be able to contain radioactive material.

Officially known as the New Safe Confinement (NSC), the at least $2 billion protective shield was constructed over Reactor 4, which caused the world’s worst nuclear disaster in 1986.

The United Nations‘ International Atomic Energy Agency (IAEA), a nuclear watchdog, revealed this month that the NSC was severely damaged in a Russian drone strike in February. 

The IAEA team conducted a safety assessment earlier this month, finding the dome had lost its primary safety functions, including confinement capability.

IAEA director general Rafael Mariano Grossi said: ‘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.’

The inspection brought some relief, confirming that the dome’s main structure and monitoring systems remain intact. 

But beneath the damaged shelter lies massive quantities of radioactive material from the 1986 disaster, making the site a ticking time bomb.

The IAEA has urged urgent repairs and upgrades to Chernobyl’s protective shelter, calling for better humidity control, advanced corrosion monitoring, and a high-tech automatic system to keep the radioactive reactor remains under control. 

The damaged dome is the latest of several such expert missions since September last year, when the substations became increasingly affected by the military conflict.

‘These substations are essential for nuclear safety and security. They are absolutely indispensable for providing the electricity all nuclear power plants need for reactor cooling and other safety systems,’ Grossi said

‘They are also needed to distribute the electricity that they produce to households and industry.’

In 2026, with support from the European Bank for Reconstruction and Development (EBRD), the Chornobyl site will undertake additional temporary repairs to support the re-establishment of the NSC’s confinement function, paving the way for full restoration once the conflict ends.

‘The IAEA – which has a team permanently at the site – will continue to do everything it can to support efforts to fully restore nuclear safety and security at the Chornobyl site,’ Grossi said in a statement……………………………………………………………………………………………… https://www.dailymail.co.uk/sciencetech/article-15393121/Chernobyl-protective-shield-radiation-leak.html
