On this day in 1957, an American nuclear plant first began producing electricity for commercial use:
Washington, Dec. 18–The country’s first large-scale civilian atomic power plant started generating electricity for commercial use today.
This milestone of the atomic age was reached early this morning when the atomic power plant at Shippingport, Pa., began producing electricity for consumers in the Pittsburgh area.
At 12:39 A. M., the Atomic Energy Commission announced, the atomic-powered generator of the Shippingport plant was tied in with the electrical system of the Duquesne Light Company.
Gradually the fission heat from the large atomic reactor was increased. By 3 A. M. the plant was producing more than the 8,000 kilowatts it consumes and was sending electricity through the Duquesne Light transmission lines.
