TMI-2

TMI-2 refers to the Three Mile Island Unit 2 nuclear reactor in Pennsylvania that experienced a partial meltdown in 1979—the most serious accident in U.S. commercial nuclear power plant history. A combination of equipment failure and human error led to a loss of coolant, causing the reactor core to overheat and damage the fuel. This release of radioactive gases was mostly contained, but it raised awareness about nuclear safety and led to significant industry and regulatory changes. The incident highlighted the importance of proper safety protocols and improved engineering design in nuclear power operations.
