The Most Dangerous Object Humanity Has Ever Created by Accident

In December 1986, beneath the ruined Reactor 4 at Chernobyl, investigators found a black, glassy mass that had melted through the building and could kill in minutes. They named it the Elephant's Foot. On April 26, 1986, the explosion at the Chernobyl Nuclear Power Plant destroyed Reactor 4 and drove its molten core down into the levels below. As it cooled, the fuel fused with sand, steel, and concrete into corium, a substance formed only a handful of times in history. In 1996, Artur Korneyev took the only known photographs of the mass, by then among the most dangerous objects ever made by accident. This film traces how the core flowed down to form the Elephant's Foot, and why, decades on, it can be contained but never removed. A steel arch now seals the site for a century, yet the mass beneath has not gone quiet, and what instruments measure inside raises a hard question: is the danger ending, or far from over?
