This week on History's Greatest Idiots (featuring Patreon member Ben Markwart), we explore the Chernobyl nuclear disaster: the catastrophic 1986 explosion that killed dozens, displaced 350,000 people, cost 700 billion dollars, and helped collapse the Soviet Union. The Safety Test That Wasn't Very Safe On 26th April 1986 at 1:23 AM, Reactor 4 at the Chernobyl Nuclear Power Plant near Pripyat, Ukraine, exploded during a safety test. Engineers disabled the emergency core cooling system, ran the RBMK reactor at just 7% power (unstable below 20%), and withdrew most control rods. Within seconds, power surged to over 100 times normal output. Two explosions blew the 2,000 ton reactor lid off and ignited the graphite moderator, which burned for nine days, releasing massive radioactive contamination across Europe.The RBMK Reactor Design The Soviet RBMK reactor had catastrophic design flaws operators weren't informed about. It featured a positive void coefficient (coolant loss increased power), control rods with graphite tips that briefly increased reactivity when inserted, and no Western-style containment building. Deputy Chief Engineer Anatoly Diatlov, in charge during the accident, genuinely believed the reactor was safe. The Cover-up and Sweden's Discovery For 36 hours, Soviet officials said nothing whilst Pripyat's 50,000 residents went about their normal lives at radiation levels 600,000 times background levels. On 28th April, radiation alarms triggered at Sweden's Forsmark Nuclear Power Plant, over 1,000 kilometres away. Only after Swedish authorities announced a Soviet nuclear accident did the USSR reluctantly admit to Chernobyl. Gorbachev didn't issue a statement until 14th May, 18 days later, calling it a "misfortune" and attacking Western media as spreading "malicious lies." The Liquidators First responders weren't told they were confronting an exposed reactor core. Firefighters handled radioactive graphite with ordinary equipment. 28 died within four months from acute radiation syndrome. Firefighter Vasily Ignatenko, aged 25, received 1,300 rem and died on 13th May 1986. About 600,000 liquidators cleaned up the site. Called "bio-robots," they shovelled radioactive debris from the roof in 40-second shifts because robots were destroyed by radiation. At least 1,800 children developed thyroid cancer from radioactive iodine-131. How Chernobyl Collapsed the Soviet Union Gorbachev later stated Chernobyl was "perhaps the real cause of the collapse of the Soviet Union," more than perestroika, glasnost, Afghanistan, or the Berlin Wall. The disaster shattered public trust, contradicting glasnost's promise of openness. Combined with Afghanistan casualties (15,000 troops), economic stagnation (2.6% GDP growth), and military spending (16% of GNP), Chernobyl's 18 billion rouble cost broke the system. The Berlin Wall fell in November 1989. The USSR dissolved in December 1991, less than six years after Chernobyl. https://www.patreon.com/HistorysGreatestIdiots https://www.instagram.com/historysgreatestidiots https://buymeacoffee.com/historysgreatestidiots Artist: Sarah Chey https://www.fiverr.com/sarahchey
