The Atomic Energy Commission is Created
After the conclusion of World War II, the US sought to discover peaceful means of using nuclear energy and created the Atomic Energy Commission.
In 1974, Congress would put an end to the AEC and split up its duties between the Energy Research and Development Administration and the U.S. Nuclear Regulatory Commission. Source: The History of Nuclear Energy -
AEC Chooses Idaho for Reactor Testing
The AEC chooses a site in Idaho for its National Reactor Testing Station.
A reactor yields the first electricity from nuclear energy more than two and a half years later in Arco, Idaho.
The energy is enough to light four light bulbs.
Arco would later become the first town to be powered by a nuclear powerplant. Source: The History of Nuclear Energy -
