Forty Years, Still Burning

At 01:23 on this day in 1986, a safety test went wrong in reactor number four at Chernobyl. The explosion tore the building apart and sent a plume of radioactive smoke into the atmosphere. Nuclear fuel burned for more than ten days. Thousands of tonnes of sand, clay, and lead were dropped by helicopter to contain the leak.[1]

The Soviet Union didn't tell anyone. Sweden detected the radiation spike two days later. The IAEA was notified on April 30. Gorbachev didn't acknowledge it publicly until May 14. Two full weeks of silence while radioactive material spread across Europe.

Estimates of the human toll range from 4,000 (a 2005 UN report) to nearly 100,000 (Greenpeace, 2006). About 600,000 "liquidators" were sent in to clean up, exposed to high levels of radiation. Many are still alive. Many are not.[2]

Today marks exactly 40 years. And the site is under threat again.

Russian forces occupied the plant on the first day of the 2022 invasion, coming through Belarus. Soldiers dug trenches in the Red Forest, named after the color the trees turned from radiation. They withdrew about a month later, but the damage was done.[3]

Then, in February 2025, a Russian drone punctured the New Safe Confinement, the massive outer shell installed in 2016 to replace the crumbling sarcophagus. According to Greenpeace, the shell cannot be repaired at the moment and can no longer function as intended. The structure designed to contain radiation for a century has a hole in it, and there is no fix available.[4]

This is what "never again" looks like in practice. The world's worst nuclear disaster, still not contained, still not safe, still making headlines for the same reason it did four decades ago: human failure compounding human failure.

We built a shell around the problem and called it solved. Then we poked a hole in it and called it war.

Chernobyl is not history. It is a slow-motion catastrophe that has simply changed shape.
