Forty Years On: Chernobyl’s Legacy, Drone Damage, and Future Risks

On 26 April 1986 Reactor 4 at the Chernobyl Nuclear Power Plant near Pripyat, Ukraine, exploded during a safety-test, releasing radionuclide clouds. Soviet Union concealed the event; IAEA cited design flaws and procedural violations. Soviet reports listed 30 deaths; estimates range 4 000-100 000 excess cancer fatalities. 49 000 Pripyat residents and 350 000 people from exclusion zone were evacuated.

In February 2025 a Russian Shahed drone pierced New Safe Confinement (NSC), a €2 billion arch built in 2016-17 to replace the original sarcophagus. The breach threatens containment of four tonnes of debris inside Reactor 4 and is estimated to need €500 million repairs to prevent corrosion and radiation release.

Deputy director Denys Khomenko stressed disciplined work and exposure times for staff repairing the NSC. IAEA reports no new releases. European Bank for Reconstruction and Development president Odile Renaud-Basso warned corrosion could undermine safety and urged funding. Ukrainian security forces guard site amid conflict.

Greenpeace Ukraine’s Shaun Burnie argues that promoting nuclear power while safety risks remain distracts from health. Soviet documents show Mikhail Gorbachev’s directive to describe the plant as under renovation, evidencing misinformation. Health impact estimates diverge: Soviet figures cite 30 deaths; independent analyses suggest up to 100 000 excess cancer cases, reflecting limited record access.

Official Soviet records list 30 immediate deaths, while independent studies estimate up to 100 000 excess cancer fatalities. Health assessments vary, with limited access to KGB archives hindering precise counts.

• “Emotions get in the way of logic, so you need to work calmly,” — Denys Khomenko, deputy director for technical operations, Chernobyl plant

The Straits Times

• “The risk is corrosion and that the structure will be undermined, and then this creates a risk in terms of nuclear safety,” — Odile Renaud-Basso, president, European Bank for Reconstruction and Development

The Straits Times

• “When we inform the public, we should say that the power plant was being renovated at the time, so it doesn’t reflect badly on our reactor equipment.” — Mikhail Gorbachev, Soviet leader

The Conversation

• “In contrast to the hype and misinformation, the probability of another severe accident remains. Unlike those in the Kremlin and the White House, who together promote nuclear power, these risks remain too great to ignore – while nuclear power remains massively uncompetitive financially.” — Shaun Burnie, Greenpeace Ukraine

The Guardian

Ukraine aims to seal NSC breach in the coming years, pending the €500 million repair fund. European Bank for Reconstruction and Development is mobilising financing, while European Commission president Ursula von der Leyen has reiterated nuclear energy’s importance, adding pressure for timely repairs. Ongoing radiation monitoring will guide future management of the exclusion zone.
