Atomic electricity generatorIn 1954, ground breaking took place at Shippingport, Pennsylvania, for the first U.S. full-scale atomic electricity generating station devoted exclusively to peaceful uses. Televised from Denver, Colorado, President Eisenhower remotely signalled a radio-controlled bulldozer. On 2 Dec 1957, the reactor reached critical power. It produced its full rated net capacity of 60 megawatts about 3 weeks later on 23 Dec. This would be sufficient to supply a city of 250,000 homes. The plant consisted of a single pressurized water-type reactor which heated steam to drive an electrical turbine-generator. The plant was formally dedicated by the same president on 25 May 1958, by remote control from Washington, D.C. It operated until 1982.* |
