 Summary:  This document provides a historical overview of the Shippingport Atomic Power Station, which achieved criticality on December 2, 1957. It describes Admiral Hyman Rickover's role in the plant's design and development. In approaching plant design, the report notes Rickover's "conservative design philosophy" and emphasis on reactor safety (7). The station's first reactor design was a pressurized water reactor (PWR), with Rickover, his Naval Reactors organization, and Westinghouse drawing upon the lessons in the design and development of the S1W (Nautilus prototype) plant, also a PWR. The basics of the PWR's seed-blanket core design are described in the document, as well as innovative aspects of the Shippingport plant that were widely adopted in the commercial nuclear power industry, including the use of "reactor containment, a structure which housed in a series of large, interconnected, vapor-tight vessels all parts of the plant containing the reactor and primary system" (3). Also, "the choice of uranium dioxide and zircaloy tubing was crucial in the history of civilian power reactors. The materials proved so successful that they were widely adopted in the civilian power industry" (10). The document also describes the Light Water Breeder Reactor (LWBR) core that was first used in operation in 1977: "Shippingport began operating on a thorium-uranium 233 core to demonstrate the feasibility of breeding in a water-cooled reactor; that is, producing more reactor fuel than was consumed" (3). The document concludes with a bibliographic essay that provides information on the Shippingport plant, including its construction, operation, and decommissioning.
