What was the significant result at Three Mile Island?Three Mile Island is the website of a nuclear reactor in south main Pennsylvania. In March 1979, a series of mechanical and human errors at the plant triggered the worst business nuclear accident in U.S. history, leading to a partial crisis that released harmful radioactive gasses into the atmosphere.
What did we learn from the Three Mile Island mishap?The TMI accident autopsy shows that the fundamental style of large pressurized water reactors inside strong containment structures was basically sound and sufficiently safe. The equipment was adequately good that, except for human failures, the significant accident at Three Mile Island would have been a small event.
