It is one of the two nuclear disasters that caused maximum severity.
The accident happened at the time of safety testing to determine the ability of the steam turbine.
The explosion is so huge that it melted the reacted core.
Three-mile Island Incident
It was a partial meltdown of the Three Mile Island, reactor in Pennsylvania, United States. More information related to this incident has been presented below:
The accident happened due to the failure of the non-nuclear secondary system.
It was followed by the stuck-open pilot-operated relief valve in the primary system.
Due to this large amount of nuclear reactor coolant escaped
It was rated Level 5 on the seven-point International Nuclear Event Scale.
