| On March 28, 1979, a stuck valve at the Three Mile Island nuclear reactor in Pennsylvania relayed a cloud of radioactive gas in the air. One hundred thousand local residents fled their homes. The accident triggered a thorough reappraisal of nuclear safety, and resulted in a complete halt in the building of nuclear plants. Even plants that were close to completion, like the Shoreham Nuclear Plant on Long Island, had their completion terminated by an invigorated anti-nuclear movement. |
