Arco is a city in Central Idaho. In 1955 Arco became the first city on Earth to be solely lit by nuclear energy.

Understand

Nearby Idaho National Laboratory, formerly known as National Reactor Testing Station and under various other names, is an important place for nuclear science and engineering development. Notable milestones are its first usable amount of electricity produced from nuclear power and the power plant for the world’s first nuclear submarine. The laboratory was also a place of the US's first nuclear accident with fatalities in 1961. The Stationary Low-Power Reactor Number One (SL-1), a US Army experimental nuclear power reactor, underwent a steam explosion and meltdown, killing three operators.
