An equipment failure and operator errors led to partial core meltdown at the plant's Unit 2 reactor around 4 a.m. on March 28, 1979.
Those gathered outside the plant offered their prayers for tsunami-devastated Japan, especially people forced from their homes by the crisis at the Fukushima Dai-ichi nuclear complex.
Three Mile Island spokesman Ralph DeSantis says the Unit 2 disaster has taught plant operators many valuable lessons.
