Drone Strike on the New Safe Confinement
Ukrainian officials say a Russian drone struck the outer shell of Chernobyl’s New Safe Confinement (NSC) in February 2025, damaging a structure that cost $2.1 billion and was completed in 2019 to encase Reactor 4. Moscow denies targeting the plant, alleging Kyiv staged the incident.
From 1986 Disaster to the $2.1 Billion Enclosure
On 26 April 1986 Reactor 4 exploded, releasing the world’s largest accidental radioactive plume and creating an exclusion zone roughly the size of Rhode Island. Decades of cleanup culminated in the NSC, an arch-shaped enclosure finished in 2019 to contain the damaged reactor and prevent further releases.
Key Figures and Numbers
- NSC construction cost: $2.1 billion.
- April 2026 strikes linked to the anniversary killed at least 16 people, including nine in Dnipro.
- IAEA-estimated repair budget for the NSC shell: at least €500 million.
Official Statements & Responses
Ukrainian officials say a Russian drone struck the outer shell of the NSC in February 2025, raising nuclear safety concerns. Moscow denied targeting the plant, alleging Kyiv staged the attack. IAEA Director General Rafael Grossi, speaking in Kyiv, said the damage required prompt repair of the outer protective shell. President Volodymyr Zelenskyy warned that “nuclear terrorism” must not be tolerated. The European Bank for Reconstruction and Development said repairs would require at least 500 million euros.
Criticism & Opposition
Ukrainian officials have condemned the attacks as nuclear terrorism, warning that they risk repeating the 1986 disaster. The IAEA has warned that further damage could compromise the safety functions of the original sarcophagus beneath the NSC.
Conflicting Reports & Gaps
Ukrainian sources attribute the damage to a Russian drone, while Russian officials claim the incident was staged. Independent verification of the strike’s specifics and of casualty figures from the broader April 2026 attacks remains unavailable, leaving a factual gap.
