The Terrifying Flaw Inside Chernobyl's Bigger Brother

On December 31, 1983, Soviet engineers activated the most powerful nuclear reactor on Earth: the Ignalina RBMK-1500. Squeezing massive output from a graphite-core design, it pushed physics to the edge of catastrophe. We analyze the hidden engineering flaws, the desperate retrofits after 1986, and the intense geopolitical standoff that forced a small nation to dismantle a global energy titan. Discover why this colossal machine remained a volatile puzzle even after the grid went dark.
