1Title:  Reactor compartment packages at the Hanford Site's trench 94 Add
 Summary:  Defueled reactor compartments from decommissioned submarines are housed in enclosures in trench 94 at the Department of Energy's Hanford Site. The defueled compartments are removed from submarines and packaged at the Puget Sound Naval Shipyard, then shipped by barge and trailer to Hanford.

2Title:  Packaged, defueled submarine reactor compartments at the Hanford Site Add
 Summary:  The defueled and packaged reactor compartments removed from decommissioned submarines are stored in trench 94 at the Department of Energy's Hanford Site. The compartments are currently stored in open dry storage and will eventually be buried in the trench. This storage is the final step in the Ship-Submarine Recycling Program (SRP), which handles the disposal of decommissioned nuclear vessels.

3Title:  IAEA/USA interregional training course on decontamination and decommissioning of research reactors and other Small Nuclear Facilities Add
 Summary:  This document, lecture notes created by Lawrence E. Boing of the Argonne National Laboratory, "presents an overview of the U.S. experiences in the decommissioning technical area" and provides information on the regulation of reactor decommissioning activities (1). Coverage includes commercial reactors, research reactors, naval reactors and prototypes, and other defense-related reactors. It includes a summary of the Ship-Submarine Recycling Program (SRP), which was created to "perform the scrapping and disposition of all U.S. Navy nuclear powered vessels" (15). As described, this is accomplished in two steps: vessel stripping, which includes defueling of the reactor plant(s) and which can be performed at several United States shipyards; and, removal of the reactor compartment and scrapping of the vessel. Finally, the report includes information on the decommissioning of the Shippingport reactor (the design and construction of which was overseen by Naval Reactors). The notes conclude with Boing emphasizing the importance of experience and information sharing in reactor decommissioning work.

4Title:  Nuclear submarines: Navy efforts to reduce inactivation costs Add
 Summary:  This 1992 General Accounting Office report analyzed the Navy's nuclear submarine deactivation program. One significant cost-reduction option, which has been put into practice, is the centralization of submarine deactivation and disposal work at the Puget Sound Naval Shipyard (PSNS). Major steps in the deactivation process include the defueling of each sub's nuclear reactor(s) and the removal of the reactor compartment for storage at the Hanford Site. As noted in the report, the "GAO's analysis shows that inactivations cost considerably less at [PSNS] that at other [nuclear-qualified] shipyards" (4). One factor in this savings is the fact that PSNS performed (and continues to perform) all reactor compartment removal and disposal work for the Navy; thus, the report suggests that all inactivation tasks be centralized at PSNS. Table 1.1 of the report lists the key events in the inactivation and disposal of a nuclear-powered submarine, including those unrelated to the propulsion system (such as missile compartment removal for ballistic missile submarines). One section of the report (pages 18-21) describes challenges in the storage of defueled reactor compartments at the Hanford Site.

5Title:  Draft environmental assessment on the disposal of naval reactors plants from USS Enterprise (CVN-65) Add
 Summary:  This document provides information on the preferred disposal plan for the eight defueled reactor plants in the USS Enterprise, the world's first nuclear-powered aircraft carrier. It lays out the timeline for Enterprise's deactivation; it "is expected to enter dry dock at Newport News Shipbuilding in Virginia for inactivation in 2013. Defueling will be conducted at Newport News Shipbuilding. Inactivation is expected to be complete in about 2017 or 2018" (1-1). At that point, Enterprise will be towed to the Puget Sound Naval Shipyard & Intermediate Maintenance Facility (PSNS & IMF) for removal of the already-defueled reactor compartments. The compartments will be packaged and shipped to the Department of Energy's Hanford Site. The actual shipment of the packages to Hanford is estimated to occur between 2023 and 2027. The assessment includes information on the estimated exposure required for the preparation and packaging of the compartments (about 300 rem of collective radiation exposure") (2-2). Page 2-6 includes a diagram that shows the locations of the eight reactor compartments on board the Enterprise, which are paired in four propulsion plants. The assessment describes the methodology for transporting the packages to Hanford and describes transport challenges and accident scenarios. The document also describes an interim "no-action alternative" to the preferred plan: placing the Enterprise in waterborne storage at the PSNS & IMF facility. This alternative has the disadvantage of "only delay[ing] ultimate permanent disposal" (2-17).
