The Chernobyl disaster occurred when technicians at nuclear reactor Unit 4 attempted a poorly designed experiment. They shut down the reactor’s power-regulating system and its emergency safety systems, and they removed control rods from its core while allowing the reactor to run at 7 percent power. These mistakes, compounded by others, led to an uncontrolled chain reaction that resulted in several massive explosions.
