Highlights

In 2004, the Department of Energy (DOE) disposed of more than 378,000 cubic meters of low-level radioactive waste (LLRW)--contaminated building rubble, soil, and debris. In 2002, DOE directed its sites to use life-cycle cost analysis to manage LLRW. Life-cycle cost analysis examines the total cost of various options to manage LLRW over its life, including its packaging, treatment, transport, and disposal, to identify the lowest-cost alternative. GAO determined whether (1) DOE sites use life-cycle cost analysis to evaluate LLRW management alternatives and (2) DOE has a strategy for cost-effectively managing LLRW departmentwide, including state actions that may affect this strategy.

Recommendations for Executive Action

Agency Affected Recommendation Status
Department of Energy To promote cost-effective LLRW management, the Secretary of Energy should prepare comprehensive guidance on life-cycle cost analysis that, at a minimum, specifies (1) a systematic, consistent method of analyzing all cost elements or of comparing key alternatives within these cost elements to determine the lowest cost; (2) when and under what circumstances sites should prepare cost analyses; (3) relevant DOE orders, manuals, or other reference materials that should be consulted to provide consistent direction on how and when to perform the analysis; and (4) how final LLRW management decisions should be documented to demonstrate that life-cycle cost factors were adequately weighed against noncost factors, such as safety, health, or schedule.
Closed - Not Implemented
According DOE's September 2010 DARTS report, DOE prepared draft guidance that provides the analytical framework for continued evaluation of waste disposal planning. The report also notes that efforts to formalize this guidance were suspended due to a variety of actions underway within the department related to waste management. The report explains that actions underway to update DOE waste disposal requirements (Order 435.1), that these actions will satisfy the GAO recommendation, and these actions will take approximately 2 years to complete. Based on these planned actions, DOE closed the recommendation. Given all the actions underway that are intended to satisfy the GAO recommendation, it is unclear why DOE closed the recommendation. DOE's December 2010 DARTS report deletes reference to the planned actions and instead reference memos from June and August 2009 that are vague and unclear as to how they specifically respond to the GAO recommendation. DOE has had more than 5 years to respond to this recommendation and they have presented no evidence they have completed actions in response to this recommendation. Until DOE presents specific evidence that they have complied with this recommendation, this recommendation will be classified as "closed-not implemented."
Department of Energy To promote cost-effective LLRW management, the Secretary of Energy should incorporate the revised life-cycle cost guidance into new or existing site contracts or into the departmental orders cited in those contracts.
Closed - Not Implemented
This recommendation is linked to recommendation 1, which we have classified as "closed-not implemented."
Department of Energy To promote cost-effective LLRW management, the Secretary of Energy should direct DOE to oversee contractors to ensure that site contractor officials properly use life-cycle cost analyses in evaluating LLRW management alternatives.
Closed - Not Implemented
This recommendation is linked to recommendation 1, which we have classified as "closed-not implemented."
Department of Energy To promote cost-effective LLRW management, the Secretary of Energy should actively promote and monitor the development of a timely, national LLRW management strategy that is based on departmentwide data on LLRW needing disposal, and ensure that the implementation of the strategy is fully carried out.
Closed - Not Implemented
This recommendation is linked to recommendation 1, which we have classified as "closed-not implemented."
