At nine o'clock in the morning on 16 September 1979, deep inside a coal mine in the Donbas, the Soviet Union set off a nuclear explosion on purpose. This was not a weapon test and not an accident. It was an industrial procedure - a small nuclear charge lowered between two coal seams and detonated to solve a problem that had been killing miners for years. The Soviets called such operations peaceful nuclear explosions, part of a program with the bureaucratic name Nuclear Explosions for the National Economy. This one was code-named Klivazh, and for decades almost no one outside a small circle knew it had happened at all.

The Yunkom coal mine, near the town of Bunhe in the Yenakiieve area, sat in a zone of intense underground tectonic stress, and that stress made the mine treacherous. The coal seams were prone to sudden, violent outbursts - the rock and coal would abruptly squeeze out gas under en...

The device was modest by nuclear standards, releasing energy equivalent to roughly 200 to 300 tons of TNT - a fraction of a bomb's yield, but detonated in solid rock far underground. The explosion carved out a cavity some five to six meters across, surrounded by a crush zone of s...

A sealed underground blast site depends on staying dry, and that is where the story turns anxious. Ukrainian ecologists had long warned that if the Yunkom mine were ever allowed to flood, water could reach the contaminated cavity and carry radioactive material into the groundwate...

Klivazh sits at the intersection of ambition and consequence. It was a product of an era that believed almost any problem, even the ancient danger of gas in a coal seam, could be solved by sufficient technological force - and for two decades of careful monitoring, that belief see...
