1Title:  Infrastructure - Naval Nuclear Propulsion Program Add
 Summary:  This diagram describes the work of the Naval Nuclear Propulsion Program, a joint Department of Energy and Navy program. Naval Reactors is "responsible for design, development, operation, and disposal of Naval nuclear propulsion plants." The program's training includes Naval Nuclear Power School (theoretical training) and prototype training, which is currently conducted on board moored ships and at the Knolls Atomic Power Laboratory's Kesselring site. NR oversees the work performed by public and private shipyards and contractual relationships with hundreds of specialized vendors. It also works with two major laboratories, Bettis and Knolls. This chart underscores the complexity of NR and the fact that its available infrastructure is managed by a relatively small central organization.

2Title:  Reactor compartment package characteristics for several submarine and surface plants Add
 Summary:  This graphic shows reactor compartment package characteristics for some submarine and surface ship reactor plants. After decommmissioning, the reactor plant(s) in a submarine or ship are removed and packaged for storage at the Puget Sound Naval Shipyard. The compartments are then shipped to and stored at the Hanford Site in Washington state. The primary system components housed inside the reactor compartment include: the reactor pressure vessel, reactor shielding, main coolant pumps, pressurizer system, and steam generators.

3Title:  Simplified view of S8G naval nuclear propulsion plant Add
 Summary:  A simplified view of the S8G reactor used to power the Ohio-class Trident ballistic missile submarines. The S8G plant's two turbines provide 60,000 shp (thermal power, shaft horsepower), approaching twice the power produced by the S6G plant used to drive the Los Angeles-class attack submarines. Admiral Hyman Rickover, head of Naval Reactors when the Trident submarine was designed in the early 1970s, supported the 60,000 shp plant, which contributed to the submarine's large size (560 feet long, with a submerged displacement of 18,700 tons).

4Title:  S5G prototype during natural circulation reactor testing Add
 Summary:  The S5G (Narwhal prototype) plant at the Idaho National Laboratory. The S5G prototype and Narwhal plants used natural circulation in the primary loop to reduce plant noise, as an alternative to forced circulation of primary coolant using reactor coolant pumps. In this photo, the prototype plant is being floated in a tank in order to determine the effects of rolling and pitching on the reactor's operation. The S5G reator achieved initial criticality on 12 September 1965. S5G was used as a training and testing prototype by Naval Reactors until the mid-1990s

5Title:  Containment structure built for the S1G prototype plant Add
 Summary:  The containment building built for the sodium-cooled, intermediate range S1G reactor plant in West Milton, New York. In January 1952, the Atomic Energy Commission's Reactor Safeguards Committee approved the construction of the S1G reactor at West Milton, provided the reactor was enclosed in a containment sphere. The 225 foot sphere, composed of one inch steel plates, was designed to contain any radioactivity release. After the sodium-cooled approach was abandoned by Naval Reactors, the S1G plant was decommissioned. The sphere was later used to house the D1G pressurized water reactor/prototype plant.

6Title:  The USS Truxtun at sea Add
 Summary:  The USS Truxtun (CGN-35), the fourth surface nuclear vessel commissioned by the Navy, and the only ship of the Truxtun class. The Truxtun was the second guided missile frigate, after the Bainbridge, and was powered by two D2G reactors.

 Summary:  An aerial view of the Naval Reactors Facility at the Idaho National Laboratory. NRF was the site of the S1W, A1W, and S5G prototypes. The site's Expended Core Facility remains open to support the processing of spent fuel from United States naval reactors.

8Title:  Pressurized-water naval nuclear propulsion system Add
 Summary:  A simplified view of the major primary and secondary components in a naval nuclear propulsion plant. The fuel elements, containing Uranium-235 pellets, are enclosed in the reactor vessel. Pressurized water is used to moderate neutrons in the reactor core and serves as the heat transfer medium. Heated water moves to the steam generator, where the heat transfer takes place between the primary and secondary loops. The main coolant pump then returns the relatively cool water to the reactor core. The pressurizer enables primary loop pressure control through heaters (to increase pressure) and spray (to reduce pressure). The steam produced in the steam generator is used to drive turbines for propulsion and electrical power.

9Title:  The USS Long Beach at sea Add
 Summary:  The USS Long Beach (CGN-9) underway. The cruiser was powered by two C1W reactors and, at the time of its 1961 commissioning, was equipped with Talos and Terrier surface-to-air missiles. The advanced weapons systems contributed to the ship's cost overrun, from an estimated 85 million to 330 million dollars (though the costs for the C1W plants also rose, from an estimated 26 million dollars to 41 million dollars). Cost overruns for the Long Beach and Enterprise helped to slow adoption of nuclear power in the surface fleet; nearly a decade would elapse between the Enterprise's commissioning and that of the next nuclear powered carrier, the USS Nimitz.

10Title:  Exterior view of the A1W prototype, Idaho National Laboratory Add
 Summary:  An exterior view of the A1W prototype plant at the Idaho National Laboratory. A1W was the prototype for the Enterprise A2W shipboard reactor plants; the prototype contained two reactors and the steam plant equipment to power one shaft. Data from the A1W prototype were also used in the design of the C1W reactor plant, which powered the USS Long Beach.
