Chornobyl Catastrophe Shelter No Longer Blocks Radiation, Needs Significant Repair – IAEA
A containment structure encasing the Chornobyl nuclear reactor within Ukraine has lost its main function of blocking radiation, as announced by the IAEA. This failure follows a drone attack earlier this year that caused significant damage in the structure.
Damage from Drone Strike Degrades Safety Structure
An attack by an unmanned aerial vehicle in February severely damaged the multibillion-euro “New Safe Confinement” arch. This enormous protective structure, built at a cost of €1.5bn with work finishing in 2019, was intended to contain radiation for decades. A recent IAEA inspection last week found that the drone impact had weakened the integrity of the steel arch.
The [protective structure] had lost its primary safety functions, including the confinement capability, stated IAEA head Rafael Grossi. He added that the mission confirmed no permanent damage to its load-bearing structures or sensor systems.
Background Context of the Chernobyl Shelter
The original 1986 disaster at the Chernobyl plant – at a time when Ukraine was a republic within the Soviet Union – spewed radiation across Europe. In a hurried containment effort, Soviet authorities constructed a concrete “sarcophagus” over the damaged reactor, but it had a 30-year lifespan. The new confinement was erected to enable the eventual dismantling of the original structure, the damaged reactor building, and the molten fuel itself.
Present Status and Required Steps
While some repairs have been carried out, agency officials emphasized that a full-scale repair effort is absolutely necessary. This is required to stop additional deterioration and to ensure long-term nuclear safety. Ukrainian authorities previously reported that a drone carrying a high-explosive warhead hit the plant, causing a fire and damaging the outer shielding.
- Radiation Readings: Reports indicated background radiation remained within safe limits following the attack with no indication of radiation leaks.
- Conflict Background: Moscow's troops occupied the Chornobyl site for over a month during the initial stages of the 2022 invasion.
- Broader Inspection: The IAEA carried out this inspection concurrently with a country-wide assessment of war damage to Ukraine's electricity infrastructure.
The situation highlight the ongoing vulnerabilities at one of the the planet's most infamous atomic accident locations amid ongoing hostilities.
