Added: 2026-05-22

[00:00:00]April 26th, still 1986.

[00:00:04]Night falls over the Chernobyl nuclear power plant, setting the stage for a looming disaster.

[00:00:10]At 1:00 a.m., chief engineer Anatoly Dyatlov oversees a low-power test, disabling safety systems in reactor S.

[00:00:20]Power surges unexpectedly. A massive steam explosion tears the reactor lid off, igniting an intense graphite fire.

[00:00:29]The burning graphite releases radioactive particles, forming a towering plume that spreads across the sky above Pripyat.

[00:00:37]An urgent alarm blares in Pripyat.

[00:00:40]Residents are told to stay indoors, delaying evacuation for hours.

[00:00:45]First responders, the liquidators, rush in with limited protection, confronting deadly radiation and a raging fire.

[00:00:53]Soviet officials conceal the severity, ordering silence while radiation levels climb unnoticed beyond the plant.

[00:01:01]On May 6th, Deputy Prime Minister Boris Shcherbina and chemist Valery Legasov hold a televised conference, admitting the catastrophe.

[00:01:11]Construction begins on a concrete sarcophagus, a massive steel shell to encase the damaged reactor and limit fallout.

[00:01:19]Today, Pripyat remains a ghost town, while the new safe confinement towers above, sealing the contaminated site.
