Employees who routinely check radiation levels at the Savannah River Site near Aiken found a wasp nest on July 3 on a post near tanks where liquid nuclear waste is stored.

True to the plot of a 1950s monster movie, an old nuclear weapons facility in South Carolina has birthed radioactive wasps, according to the U.S. Department of Energy. The discovery was made July 3 at the 310-square-mile Savannah River Site in Aiken, which produced plutonium and tritium for nuclear weapons during the Cold War.
