It was the worst nuclear accident in U.S. history. On March 28, 1979, a nuclear reactor at the Three Mile Island power plant had a failure and almost suffered a cataclysmic meltdown. For three days, the nation was terrified, most notably those who lived near the plant sitting on a small island in the Susquehanna River in rural Pennsylvania. Over 100,000 people evacuated. Officials claim the radiation leakage was negligible, but residents blame the accident for a surge in illnesses, including cancer. Marvin Scott covered the accident 40 years ago, and returned last week to take another look for this morning's WPIX News Closeup which also featured environmental attorney Peter D. Wolf, CEO of Nuclear Energy Solutions, Inc. and Karl Rabago Executive Director, Pace Energy and Climate Center. Do you think we are prepared for another accident like Three Mile Island?
