Startling Revelations about Three Mile Island Disaster Raise Doubts Over Nuke Safety

This story originally appeared on Facing South, online magazine of the Institute for Southern Studies.

It was April Fool's Day, 1979 -- 30 years ago this week -- when Randall Thompson first set foot inside the Three Mile Island nuclear power plant near Middletown, Pa. Just four days earlier, in the early morning hours of March 28, a relatively minor problem in the plant's Unit 2 reactor sparked a series of mishaps that led to the meltdown of almost half the uranium fuel and uncontrolled releases of radiation into the air and surrounding Susquehanna River.

It was the single worst disaster ever to befall the U.S. nuclear power industry, and Thompson was hired as a health physics technician to go inside the plant and find out how dangerous the situation was. He spent 28 days monitoring radiation releases.

Today, his story about what he witnessed at Three Mile Island is being brought to the public in detail for the first time -- and his version of what happened during that time, supported by a growing body of other scientific evidence, contradicts the official U.S. government story that the Three Mile Island accident posed no threat to the public.

"What happened at TMI was a whole lot worse than what has been reported," Randall Thompson told Facing South. "Hundreds of times worse."

Thompson and his wife, Joy, a nuclear health physicist who also worked at TMI in the disaster's aftermath, claim that what they witnessed there was a public health tragedy. The Thompsons also warn that the government's failure to acknowledge the full scope of the disaster is leading officials to underestimate the risks posed by a new generation of nuclear power plants.

While new reactor construction ground to a halt after the 1979 incident, state leaders and energy executives today are pushing for a nuclear energy revival that's centered in the South, where 12 of the 17 facilities seeking new reactors are located.

Fundamental to the industry's case for expansion is the claim that history proves nuclear power is clean and safe -- a claim on which the Thompsons and others, bolstered by startling new evidence, are casting doubt.

An unlikely critic

Randall Thompson could never be accused of being a knee-jerk anti-nuclear alarmist. A veteran of the U.S. Navy's nuclear submarine program, he is a self-described "nuclear geek" who after finishing military service jumped at the chance to work for commercial nuclear power companies.

He worked for a time at the Peach Bottom nuclear plant south of Three Mile Island in Pennsylvania's York County, but quit the industry six months before the TMI disaster over concerns that nuclear companies were cutting corners for higher profits, with potentially dangerous results. Instead, he began publishing a skateboarding magazine with his wife Joy.

But the moment the Thompsons heard about the TMI incident, they wanted to get inside the plant and see what was happening first-hand. That didn't prove difficult: Plant operator Metropolitan Edison's in-house health physics staff fled after the incident began, so responsibility for monitoring radioactive emissions went to a private contractor called Rad Services.

The company immediately hired Randall Thompson to serve as the health physics technician in charge of monitoring radioactive emissions, while Joy Thompson got a job monitoring radiation doses to TMI workers.

"I had other health physicists from around the country calling me saying, 'Don't let it melt without me!" Randall Thompson recalls. "It was exciting. Our attitude was, 'Sure I may get some cancer, but I can find out some cool stuff.'"

What the Thompsons say they found out during their time inside TMI suggests radiation releases from the plant were hundreds if not thousands of times higher than the government and industry have acknowledged -- high enough to cause the acute health effects documented in people living near the plant but that have been dismissed by the industry and the government as impossible given official radiation dose estimates.
