The Three Mile Island accident was a partial nuclear meltdown of the Unit 2 reactor (TMI-2) of the Three Mile Island Nuclear Generating Station on the Susquehanna River in Londonderry Township, near Harrisburg, the capital city of Pennsylvania, United States. The reactor accident began at 4:00 a.m. on March 28, 1979, and released radioactive ...
The effects of the 1979 Three Mile Island nuclear accident are widely agreed to be very low by scientists in the relevant fields. The American Nuclear Society concluded that average local radiation exposure was equivalent to a chest X-ray and maximum local exposure equivalent to less than a year's background radiation.

Three Mile Island accident. During the Three Mile Island accident, a slow partial meltdown of the reactor core occurred. About 41,900 pounds (19,000 kg) of material melted and relocated in about 2 minutes, approximately 224 minutes after the reactor scram.
The 1979 Three Mile Island accident was a pivotal event that led to questions about U.S. nuclear safety. Earlier events had a similar effect, including a 1975 fire at Browns Ferry, the 1976 testimonials of three concerned GE nuclear engineers, the GE Three.
