11Title:  USS Scorpion, Skipjack-class attack submarine Add
 Summary:  The USS Scorpion (SSN-589), a Skipjack-class submarine that was powered by an S5W reactor plant. The Scorpion was lost at sea on 5 June 1968; the cause of the submarine's loss was never definitively determined.

12Title:  The USS Skipjack, first submarine driven by S5W plant Add
 Summary:  The USS Skipjack, the first boat on which the S5W reactor was installed. The S5W core was designed by Westinghouse's Bettis Atomic Power Laboratory. Unlike the S2W plant installed in the Nautilus, the S5W was designed and built without the benefit of a land-based prototype. The most significant improvements in the S5W design, relative to earlier Bettis-designed reactors, involved "the reactor core, including the fuel assemblies and the control rods" (282). These components could be tested at the Bettis laboratory without a full-scale prototype being constructed. The S5W, the submarine fleet reactor, was used to power nearly 100 fast attack and ballistic missile boats.

13Title:  NR-1 control and instrument panels Add
 Summary:  Interior of NR-1, showing the submarine's instrument and control panels. NR-1 was powered by a small, low-power pressurized water reactor. The submarine was capable of speeds of 3.5 knots per hour when submerged, and had forward and aft wheels, enabling her to work on the ocean floor.

14Title:  S1W propulsion plant - view from the floor Add
 Summary:  View of the S1W prototype plant, looking aft to forward. The water tank on the right surrounded the reactor compartment. This design enabled Naval Reactors to assess the reflection of radiation from the core and primary system back into the hull. The cylindrical hull contained the engine rooms and a maneuvering room (the control room for the reactor and propulsion systems). The S1W plant achieved initial criticality on 30 March 1953. In June, the S1W plant successfully completed a 100 hour continuous run, illustrating that nuclear-powered submarines would revolutionize naval operations.

15Title:  The George Washington underway Add
 Summary:  The USS George Washington, the first Polaris missile submarine. The George Washington was the lead boat in her class and was powered by an S5W reactor plant. In November 1960, the she began submerged patrols, providing the United States with a secure ballistic missile capability.

16Title:  Aerial view of General Dynamics Electric Boat Add
 Summary:  An aerial photo of the General Dynamics Electric Boat yard in Groton, Connecticut. Electric Boat designed and built the first two nuclear submarines, the Nautilus and the Seawolf, and served as the lead yard for the early nuclear submarine classes, such as Skate and Skipjack. Electric Boat continues its pivotal role in submarine design and construction, including its lead yard responsibility for the USS Virginia (SSN-774) class of attack submarines.

17Title:  Main control console at Shippingport (looking north) Add
 Summary:  The main control console for the Shippingport Atomic Power Station. While the Naval Reactors organization, working with Westinghouse, led the design and development of the Shippingport reactor, some aspects of the plant - such as the large size of the control panels and the use of concrete for shielding - were quite different when compared with the submarine reactor plants that had been designed and built under NR's oversight.

18Title:  Main coolant pump, lower section, at the Shippingport Atomic Power Station Add
 Summary:  A reactor coolant pump at the Shippingport Atomic Power Station. The pump circulated water (which served as both coolant and moderator in the pressurized water reactor plant) through the core and the steam generator. One centrifugal pump was installed in each of the plant's four reactor coolant loops. Each pump had two operating speeds, to save electrical power when the plant was operated at below 50% reactor power.

19Title:  Lower section of plant pressurizer, Shippingport Atomic Power Station Add
 Summary:  The lower section of the pressurizer at the Shippingport Atomic Power Station. In a pressurized water reactor plant, the pressurizer is used to maintain satisfactory operating pressure. Primary pressure in increased through the operation of the removable heating elements visible on the right side of the pressurizer. Pressure is reduced through a spray nozzle at the top of the unit. The pressurizer is connected to the primary coolant system through the surge line (entering the bottom of the pressurizer) and the spray line (entering at the top). During normal power operations, steam is present above the pressurizer's water volume.
