=Three Mile Island Accident= The[| Three mile island] accident happened in 1979 March 28.[3]This [|nuclear power] plant was one of the worst nuclear disasters in history.[3]No one planed for it to happen It just happened.

How does a nuclear power plant work?
[|Enriched uranium] typically is formed into inch-long (2.5-centimeter-long) pellets, each with approximately the same diameter as a dime.[5] Next, the pellets are arranged into long rods, and the rods are collected together into bundles.[5] The bundles are submerged in water inside a pressure vessel.[5] The water acts as a coolant.[5] Left to its own devices, the [|uranium] would eventually overheat and melt.[5]



How did it happen?
There was a manufacturing problem in the cooling tower.[1]All sorts of lights were beeping so they turned off the emergency water.[1]But by doing that they didn't save the plant they just put the city of Harrisburg in jeopardy.[1]If they left the plant alone the plant would have saved itself.[1]By turning the water off most of the core in the cooling tower was melted.[3]After that there was a sign that there was radiation in the control room.[1] Then a man named Gary Miller turned the emergency water back on in the nuclear power plant.

Where and when did it happen?
[|Three mile islands] nuclear disaster happened on march 20 1979.[1][|Three mile island] is about 10 miles from [|Harrisburg].[1]Everybody in[| Harrisburg], [|Pennsylvania] was not aware that [|Three mile island]was heading trowed melt down.[1][|Harrisburg] is the capital of Pennsylvania.[4] [|Harrisburg] lies along the edge of the[| Susquehanna River].[4]Three mile island is near Middletown PA.[6]
