Chernobyl’s Protective Shield Is Failing: Experts Warn of a Looming Nuclear Safety Crisis

This revelation has triggered concern not only among nuclear scientists and engineers, but also among governments, environmental organizations, and international legal bodies tasked with safeguarding nuclear sites in times of peace and war. The situation has evolved rapidly over the last year, particularly following a drone attack on February 14, 2025, which appears to have critically damaged the protective structure’s exterior.
A Shelter Designed to Last a Century
To understand the current crisis, it’s essential to revisit the history and purpose of the New Safe Confinement.
Following the catastrophic explosion at Reactor No. 4 of the Chernobyl plant in April 1986, the Soviet Union constructed an emergency concrete sarcophagus intended to encase the radioactive remains of the reactor and limit the spread of radiation. This temporary structure, hastily built under hazardous conditions, was never expected to endure long-term environmental degradation.
Recognizing the need for a more resilient solution, an international consortium of governments and institutions funded and constructed the New Safe Confinement — a vast, arch-shaped steel structure designed to enclose the decaying sarcophagus completely. Completed in 2019 at a cost of more than $1.7–$2.2 billion, the NSC was hailed as a milestone in nuclear engineering. It was intended not only to contain radiation but also to facilitate the eventual disassembly and safe management of the reactor remains over decades.
The NSC was designed to withstand natural hazards including severe weather, and external wear for at least 100 years. But it was not built to withstand direct military attack — a vulnerability that would soon have profound consequences.
The February 2025 Drone Strike
On February 14, 2025, during the ongoing conflict between Ukraine and Russia, a drone — identified by Ukrainian authorities as Russian — struck the Chernobyl site, hitting the roof of the New Safe Confinement. The impact ignited a fire that burned for days in the insulation and outer shielding layers of the structure.
However, the drone’s explosive impact pierced the protective cladding, burned into insulation, and created structural openings in the NSC’s exterior shell. Some reports estimate the damaged area at approximately 15 square meters of breach, with further areas affected by subsequent firefighting efforts.
While the load-bearing frame of the NSC reportedly remained generally intact and the radiation monitoring systems continued to function, the damage to the outer shell compromised the containment barrier — the very feature designed to isolate the reactor’s hazardous materials from the environment.
This compromise now means that the structure cannot fully prevent water, wind, or other environmental factors from interacting with radioactive debris inside, a situation scientists say could eventually lead to increased leakage risks if not fully restored.
IAEA Assessment: “Primary Safety Functions Lost”
The International Atomic Energy Agency (IAEA), the United Nations’ nuclear watchdog, dispatched a team of experts for a comprehensive safety assessment of the NSC in late November 2025. Their findings — published in early December — confirmed what earlier reports had warned: the New Safe Confinement has lost its essential safety functions, including its core confinement ability.
IAEA Director General Rafael Mariano Grossi emphasized that limited temporary repairs had been undertaken, particularly to the roof, but stressed that comprehensive restoration is essential to prevent further degradation and to ensure the long-term nuclear safety of the site.
Notably, the assessment also found that no irreversible damage occurred to the structure’s load-bearing elements or monitoring systems, leaving room for repair rather than total replacement. However, experts warn that partial fixes will not be sufficient to restore full containment capability if the integrity of the outer barriers continues to deteriorate.
