11Title:  Thermal shields centered over reactor vessel Add
 Summary:  The thermal shield positioned above the Shippingport reactor vessel. The core's thermal shields consisted of two stainless steel cylinders which rested inside the vessel. The shields reduced the core's radiation and, thus, the heat generated in the reactor's pressure vessel.

13Title:  Reactor vessel closure head Add
 Summary:  The closure head is lowered to the top of the reactor vessel in the Shippingport Atomic Power Station. The closure head had 46 penetrations; 32 for the control rod drive mechanisms, along with refueling and instrumentation ports. The closure head was bolted and welded to the lower section of the reaction vessel to create a pressure-tight and leak-tight seal.

14Title:  Main coolant pump removed from operation Add
 Summary:  A reactor coolant pump removed from operation in the Shippingport Atomic Power Station. The Shippingport reactor used four reactor coolant pumps, one for each primary loop. The single-stage, leak proof centrifugal pump supported the flow of coolant in the primary system; in addition to the coolant flow through the pump, lower temperature water circulated within the pump to remove heat and lubricate the motor bearings. The pump was powered by a 2,300 volt electric motor that supported full-speed and half-speed operations.

15Title:  Foster Wheeler straight tube steam generator Add
 Summary:  One of the two Foster Wheeler straight tube steam generators being placed in a boiler room in the Shippingport Atomic Power Station. Each generator contained 2,096 stainless steel tubes, with each tube having an outer diameter of one-half inch. The heads of the steam generator each had 18 inch pipe connections to the secondary system.

16Title:  Babcock & Wilcox U-shell design steam generator Add
 Summary:  One of the two Babcock & Wilcox Company U-shell steam generators being placed in a boiler room at the Shippingport Atomic Power Station. Each steam generator contained 921 stainless steel tubes, with an outside diameter of 3/4 inch. The U-shaped shells were 38 inches in diameter. It had two hemispherical heads with pipe connections through which primary coolant entered and exited the steam generator.

17Title:  Downcomers and risers piping, Shippingport secondary plant Add
 Summary:  Piping for downcomers and risers in the B loop of the Shippingport Atomic Power Station. These pipes connected the loop's Babcock & Wilcox U-shell steam generator with a steam drum, and through the steam drum with the plant's secondary system.

18Title:  Seed fuel assembly being removed from reactor vessel by an extraction crane Add
 Summary:  A highly-enriched Uranium fuel element is removed from the Shippingport reactor core in 1960. Alvin Radkowsky, the chief physicist for Naval Reactors, "suggested the possibility of using a 'seed' of highly-enriched uranium surrounded by a much larger 'blanket' of natural uranium" (244). This core design approach offered several advantages, including ease of refueling (by replacing the seed elements), and was employed in the Shippingport reactor cores during the plant's operations, including the Light-Water Breeder Reactor (LWBR) core that was used from 1977 to 1982.

19Title:  Project Prometheus Reactor Module final report Add
 Summary:  This report describes the work of the Naval Reactors program's contractor laboratories - the Knolls Atomic Power Laboratory and the Bettis Atomic Power Laboratory - in NASA's Project Prometheus. Naval Reactors worked as NASA's partner in the design of a civilian space reactor for a 15-20 year mission. The first identified mission was the Jupiter Icy Moons Orbiter (JIMO). Five reactor designs were evaluated by Naval Reactors, with the direct gas Brayton plant deemed the most promising design. NR investigated a number of issues, including plant design, instrumentation and control, and core and plant materials. In performing this research, Naval Reactors determined that the existing state of reactor technology did not support the creation of a plant that would enable mission goals to be met. The Prometheus project was ended in 2005.

20Title:  Request for Naval Reactors comment on Project Prometheus Add
 Summary:  A formal request, from the Naval Reactors Prime Contractor Team (NRPCT) to Naval Reactors requesting comment on the reactor safety requirements for NASA's Project Prometheus. Project Prometheus was created in 2003 to design reactors for long-duration space missions. The NRPCT, requesting the review, included engineers from Lockeed Martin, the Knolls Atomic Power Laboratory, and the Bettis Atomic Power Laboratory (the latter two being long-time contractors for Naval Reactors). The letter describes the team's primary goal: "Consistent with Naval Reactors program philosophy...no undue risk to the health and safety of workers, the public, or adverse effects to the environment should result from activities associated with the nuclear reactor of the Prometheus project."
