Shippingport Nuclear Power Plant - Reactor Internal

In 1956, S. Morgan Smith manufactured the Reactor Internals for the Shippingport Nuclear Power Station.  This facility was the first commercial central electric generating station in the United States to use Nuclear Energy.  The plant was dedicated on May 26, 1958 by President Dwight D. Eisenhower as part of the “Atoms for Peace” program. 

In 1959 Allis-Chalmers acquired the business and entered other energy markets, manufacturing both commercial and military nuclear power equipment.

In 1983 Precision Custom Components was formed as a privately held company and continues the traditions of workmanship and superior quality in the production of heavy precision metal fabrications.

Today PCC is recognized as a world class producer of energy related equipment for commercial and government markets.
