40 Years On: War-Damaged Safeguards at Chernobyl

The Drone Strike and Its Immediate Consequences
On 14 February 2025 a Russian Geran-2 drone struck the north-west face of the New Safe Confinement (NSC) at the Chernobyl Nuclear Power Plant. The impact punched a 15 m² hole through both outer and inner walls at roughly 85 m above ground, ignited a rubber sealing membrane, and set off a fire that burned for three weeks. Workers cut 332 additional holes to reach hotspots with water hoses. The strike disabled the NSC’s confinement function, its humidity-control system, and compromised the structure’s ability to contain any future radioactive release from the underlying sarcophagus.
From 1986 to the New Safe Confinement
The original accident on 26 April 1986 released the world’s largest accidental radioactive plume, killing 28 people from acute radiation syndrome and prompting the evacuation of 49 000 Pripyat residents and roughly 116 000 people from the surrounding area. In 2019–2020 the NSC—a $2.1-$2.5 billion steel arch funded by 45 countries—was erected to enclose the hastily built 1986 sarcophagus and to buy time for its safe dismantling.
Timeline of Key Events
- 26 Apr 1986 – Reactor 4 explosion.
- 2019-2020 – Completion of the NSC.
- 24 Feb 2022 – Russian forces occupy the plant during the invasion of Ukraine.
- 14 Feb 2025 – Drone strike damages NSC.
- 26 Apr 2026 – 40th anniversary of the disaster.
Data & Statistics
- Exclusion zone: ? 2 200 km² in Ukraine, ? 2 600 km² in Belarus; uninhabitable for ? 24 000 years (IAEA).
- Daily cleanup workforce: ? 600 people; total engineering staff: ? 2 200.
- Liquidators in 1986–1990: ? 600 000.
- NSC design lifespan: 100 years; repair cost estimate: up to €500 million.
- Damage: 15 m² breach, 332 auxiliary holes, three-week fire.
Why It Matters: Nuclear Safety in a Conflict Zone
If the sarcophagus beneath the NSC collapses, more than 100 tonnes of nuclear fuel could be released, endangering workers and neighboring populations. The war-induced damage also forces the plant’s director-general to pause dismantling work, potentially extending the timeline by a decade. International confidence in nuclear-safety protocols is therefore linked to the ability to restore the NSC’s core functions amid ongoing hostilities.
Official Statements & Responses
- Plant director-general Serhii Tarakanov warned that a sarcophagus collapse would “release over a hundred tonnes of nuclear fuel into the air.”
- Deputy technical director Oleksandr Skomarokhov described the strike as “critical” and noted the immediate loss of confinement capability.
- The International Atomic Energy Agency (IAEA) expressed “deep concern” that the damage could shorten the NSC’s 100-year lifespan.
- Greenpeace Ukraine, citing engineer Eric Schmieman, called the breach a “destruction of the main functions of the new safe confinement” and highlighted a €500 million repair gap.
- Ukrainian officials have requested accelerated funding, while Russian authorities deny targeting the facility.
Criticism & Opposition
Ukrainian officials argue that the state’s cash-strapped budget cannot meet the €500 million repair estimate, risking prolonged exposure. Greenpeace and independent experts stress that without timely repairs the sarcophagus could fail, releasing radioactive material. Russian denial of responsibility is contested by Ukrainian investigators who attribute the strike to a deliberate attack.
Conflicting Reports & Gaps
- Soviet official death toll (31) contrasts with UN estimates of 4 000 and Greenpeace estimates approaching 100 000 long-term fatalities.
- IAEA monitoring reported no immediate rise in external radiation after the drone strike, whereas Greenpeace warns of potential future releases.
- Estimates of daily cleanup personnel vary between 600 workers (National Geographic) and 2 200 engineers (Los Angeles Times).
Verbatim Quotes
- “If the sarcophagus collapses, over a hundred tonnes of nuclear fuel would be released into the air,” — Serhii Tarakanov, plant director-general.
- “We witnessed shelling before, but I knew they would only wake me if something critical had happened,” — Oleksandr Skomarokhov, deputy technical director.
- “The Russian drone strike destroyed the main functions of the new safe confinement,” — Eric Schmieman, engineer, Greenpeace Ukraine.
- “We had no hope we would make it out alive — it was really that scary,” — Liudmyla Kozak, plant worker.
- “I have seen a lot in my life, but I couldn’t imagine that war would come here,” — Natalia, long-serving plant employee.
What’s Next
Ukraine seeks international financing to repair the NSC within four years, aiming to restore its 100-year design life. Simultaneously, security measures are being heightened to prevent further strikes, and the IAEA continues radiation monitoring. The outcome will determine whether Chernobyl remains a contained legacy or re-emerges as a nuclear-safety flashpoint.
