Nuclear accidents and risk
For a long time, a nuclear disaster was deemed unlikely. Nuclear energy was presented as carefully monitored. But when half of the core of a reactor melted in the Three Miles Island (TMI) nuclear power station in the United States in 1979, concern grew. Even though there were no casualties and the radiation was confined by the security system, the accident led to the suspension of the United States' civil nuclear program. For those against nuclear power, this was proof that accidents could indeed happen.
