History

Historical Context

The 1979 Three Mile Island accident led to significant changes in U.S. nuclear energy policy, resulting in stricter safety regulations and a halt in new reactor construction for decades. By 2020, only 104 reactors were operational. As the U.S. aims for 300 GW of nuclear power by 2050, the focus has shifted to Small Modular Reactors, addressing aging infrastructure and reducing fossil fuel reliance.
