1Title:  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.

2Title:  Nuclear-powered ships: Accounting for shipyard costs and nuclear waste disposal plans Add
 Summary:  This 1992 GAO report describes accounting practices at shipyards that perform nuclear work, using the Puget Sound Naval Shipyard in Bremerton, Washington as the basis for the review. The report describes the higher costs for nuclear work, compared with non-nuclear work, at PSNS, attributing them to "the complex nature of nuclear work, which requires a greater level of services, and the higher cost of specially trained and skilled workers and specialized shipyard departments that support nuclear work, such as radiological control, nuclear engineering, nuclear planning, and nuclear quality assurance" (3). Appendix III includes information on the disposal of hazardous waste, including defueled reactor compartments from decommissioned nuclear-powered submarines.
