Three Mile Island

How it Happened

The melt down happened when the water cooling stopped working, causing an over heating in the second reactor. The human and systematic problems caused the reactor to start melting.

It happened on march 28 1979 in Harrisburg Pennsylvanian. specifically Dauphin county, the incident was rated 5 on the 7 point international nuclear event scale.

Fuel rods melted and control rods melted and all of the water in the cooling system turned to steam. By early morning the core had heated to over 4000 degrees and that was just 1000 degrees from a melt down. During the melt down the core melted, causing radiation to drift all across the area. Affecting people plants and livestock.

After the first couple of days pregnant women and preschoolers were evacuated within a 10 mile area of the melt down. Cows stared to die and their calves could not walk, and people stared to see birth defects in piglets.

The way people tried to solve this problem was evacuation. Radiation is something that can not be taken away it will go away but after a long period of time. There for the only way to avoid it is to evacuate the effected area.

The way we can avoid accidents like this in the future is having nuclear power plants on uninhabited areas or islands where their is not a population of people or wild life that can be affected. This could prevent disasters like this in the future.
