Just looking at those words probably makes you squirm - especially if you can remember the Cold War. It is the force that powers large ships of war. It's the force behind the most destructive bombs ever devised by human minds. Heck, it's the stuff that's responsible for the Blob, giant mutant insects and Godzilla.

|The Three Mile Island reactor in 1979|
It started with a bad control board design that failed to indicate the proper position of a Pilot Operated Relief Valve, which allowed the reactor's coolant to leak out without the operators noticing. By the time a change of shift happened a few hours later, the reactor's core was exposed above the coolant, and the fuel rods began to melt. It was an event known as a loss of coolant accident.

Now, understand that while the reactor's fuel was melting, it was also encased inside of a reactor vessel and a containment building, providing a significant amount of protection against a release of radioactive material (These important safety devices were missing in the Chernobyl reactor, making that accident much more serious). Plus, due to the type of fuel used in a nuclear plant, there is no chance of a nuclear explosion like an atomic bomb. It just can't happen.

Angry at the utility, the Commonwealth of Pennsylvania turned to the Nuclear Regulatory Commission for guidance. While this did add subject matter experts to the incident, very little coordination between the agencies compounded the confusion.

It wasn't until President Jimmy Carter, a former Navy nuclear technician who understood ionizing radiation and the level of threat, showed up on scene to tour the facility - and observe the operations in the control room - that the public began to breath a little more easily.
While the event fortunately didn't lead to a catastrophic loss of life, it did open the eyes of emergency managers to the importance of bringing public information officers into a disaster early on. In fact many of the tenants of the National Incident Management System were established in the months and years after this accident.
As far as the lessons public information lessons learned, you can read the after action report online... an interesting case study.
