Who Destroyed Three Mile Island?
summary
A control-room decision chain lets a small plumbing fault become a partial meltdown: a leaking pilot-operated relief valve floods the sump, operators see rising pressurizer level and turn off high pressure injection after 2½ minutes, then later close a block valve that seals in heat. About 30 tons of fuel melt, cleanup costs ~$1 billion and takes 14 years, containment prevents a public radiation release, and post‑accident inquiry rewrites procedures and training.
