"Power Plant, which was the source of two of the top five highest conditional core damage frequency nuclear incidents in the United States since 1979, according to the U.S. Nuclear Regulatory Commission. Despite the concerns which arose among the public after the Three Mile Island incident, the accident highlights the success of the reactor's safety systems. The radioactivity released as a result of the accident was almost entirely confined within the reinforced concrete containment structure. These containment structures, found at all nuclear power plants, were designed to successfully trap radioactive material in the event of a melt down or accident."

Anti-nuclear movement activists expressed worries about regional health effects from the accident. However, epidemiological studies analyzing the rate of cancer in and around the area since the accident, determined there was a small statistically non-significant increase in the rate and thus no causal connection linking the accident with these cancers has been substantiated.
