The accident at Three Mile Island was caused due to failures in the non-nuclear secondary system, which caused large amounts of nuclear reactor coolant to escape. It was only partial because only one of the reactors had a failure on the entire Three Mile Island Generator. For short, the reactor was called TML - 2.
Considered the most significant accident in the US nuclear power plant history, this incident formed worries in the minds of the general public and environmental activists. This also forced new safety regulations to be made concerning nuclear plants.
President Carter signed into law a stricter federal safety standards, including, mandatory emergency evacuation plans and harsher penalties for violations of federal safety standards. He also required plants to hire inspectors and set up a strict training program for them. As the budget increased, so did the inspectors.

Activists, mainly environmentalists and people who had been affected by similar incidents, attacked the TMI and its carelessness. They filed a suit in 1981 against the TMI, winning $25 million. They used this to create the TMI Public Health Fund.
Today, this plant still operates, but with better safety regulations and stricter policies. The second reactor lays unused since the accident, but the first reactor is still functional.
