Remembering the Three Mile Island meltdown 45 years later

The eyes of the world were on an obscure island in the Susquehanna River 45 years ago Thursday as the worst nuclear accident in American history was unfolding at Three Mile Island.

The reactors no longer produce energy and the place is mostly quiet, but nearly a half century later there is still fallout.

At the time the meltdown was partial, but the panic was much more than that.

“All of a sudden all of these parents start to rush to the front of the school, and they look so scared and frightened and frantic,” said Maria Frisby, who lived near Three Mile Island and was in class at Middletown High School.

“I had a strong metallic taste in my mouth. I never tasted anything like that before,” she recounted.

Now 45 years later there’s a new exhibit remembering the disaster.

“This has been our most popular exhibit yet,” said Taylor Mason, an archivist for the Pennsylvania House.

The exhibit includes a timeline, documents from a special investigating committee, t-shirts, vintage photos, and video from the incident.

“I learned the biggest thing was how passionate people were about it and how nervous they were,” said Mason. “This never happened before, really. So it was a really big time in Pennsylvania’s history.”

Maria Frisby says there are still people who are feeling the effects of TMI, insisting neighbors, friends, and classmates were exposed to radiation that day and are still suffering.

“They’re dying,” she said. “It’s just too many. It’s a big, big cancer cluster.”

The medical studies are mixed; the science is spotty at best.

“The reason we don’t have the data is that the industry wasn’t prepared,” said Eric Epstein with TMI Alert. “The company, whether they did it intentionally or unintentionally, are simply not prepared to gauge the amount of radiation that was released.”

Epstein has run the nuclear watchdog TMI Alert for 42 years and says while the reactors are closed there’s still much to keep an eye on.

“It would be foolish to think that you look at the plants and there’s no danger. That’s absolutely not the case. TMI two is still highly radioactive, and TMI one has tons of spent fuel onsite on an island in a river. You know, not a great formula for security.”

Three Mile Island starts decommissioning Unit 2

Things are quiet on the island right now with a lengthy decommissioning underway. We’re still decades away from completion at Three Mile Island.
