![]() However, studies have found no evidence of adverse health and environmental consequences. The Three Mile Island accident alarmed the surrounding communities. Half of the TMI-2 reactor’s core melted down, resulting in the release of a small amount of radioactive gases and iodine into the environment. On March 28, 1979, one of the two reactors at the Three Mile Island (TMI) plant in Middletown, Pennsylvania experienced a partial meltdown. If the reactor core is fully contained, the major concern is whether there is any release of contaminated air or liquids into the environment. However, when the core of the reactor melts down it stops the reaction there is no possibility of an atomic explosion. A core meltdown is when the reactor’s core severely overheats and cannot be sufficiently cooled down. This fear is generally fueled by three high-profile nuclear accidents: Three Mile Island, Chernobyl, and Fukushima Daiichi.Įach of these accidents involved a partial or full core meltdown. ![]() ![]() One of the main reasons people are fearful of nuclear power is the possibility of accidents. While nuclear reactions produce huge amounts of energy and emit few greenhouse gases, nuclear power has been a source of controversy among governments, experts and the public. This steam is used to power a turbine to generate electricity. In the core of the nuclear reactor, the heat from fission or splitting of uranium atoms is used to produce steam. Following World War II, countries around the world began to develop nuclear reactors to meet civilian energy needs.
