Background and Information leading to the incident
The meltdown at Three Mile Island is a combination of both mechanical failure and human error. Mechanical failure was first observed at the non–nuclear part of the plant where failure in the main feed water pumps prevented the supply of water to the steam generators further cutting the heat in the core reactor. Increasing heat in the turbine generator lead to turbine shut down causing increased pressure in the nuclear portion of the plant. With the increasing pressure pilot control relief valve opened up which, further caused the cool water to drain causing overheating. To these series of complication a mixture of human error was added which lead to further complications. The operators decided
