What Software Engineers Can Learn From the Chernobyl Disaster
summary
Shows how an RBMK reactor’s positive scram and lack of a containment building turn routine procedures into catastrophe: inserting control rods with graphite tips (the AZ-5 emergency button) briefly increases reactivity, core ruptures and two explosions occur, and graphite ignites. Helicopters drop ~5,000 tons of sand, lead and boron with little effect, 100,000 workers build a hastily leaking sarcophagus, a steel new safe confinement opens in 2017, and a 2024–25 drone strike causes ~ $100M of damage to its safety functions.
