Reports & Testimonies

  • GAO’s recommendations database contains report recommendations that still need to be addressed.

    GAO’s recommendations help congressional and agency leaders prepare for appropriations and oversight activities, as well as help improve government operations. Recommendations remain open until they are designated as Closed-implemented or Closed-not implemented. You can explore open recommendations by searching or browsing.

    GAO's priority recommendations are those that we believe warrant priority attention. We sent letters to the heads of key departments and agencies, urging them to continue focusing on these issues. These recommendations are labeled as such. You can find priority recommendations by searching or browsing our open recommendations below, or through our mobile app.

    Recommendation: To ensure that DOE has a full understanding of the department's long-term TRU waste disposal requirements and the capability of WIPP to meet those requirements, the Secretary of Energy should develop a schedule for deciding whether the volumes of "potential waste" identified in the annual TRU waste inventory report can be disposed of at WIPP.

    Agency: Department of Energy
    Status: Open

    Comments: When we confirm what actions the agency has taken in response to this recommendation, we will provide updated information.
    Recommendation: To ensure that DOE has a full understanding of the department's long-term TRU waste disposal requirements and the capability of WIPP to meet those requirements, the Secretary of Energy should develop guidance that helps sites produce a more comprehensive estimate for the volumes of TRU waste that may be generated in the future from cleanup operations, including estimates of buried waste, waste that may be generated from decontamination and decommissioning of nuclear facilities, and waste that may be generated past WIPP's expected closure date of 2050.

    3 open recommendations
    Recommendation: To enhance DOE's ability to make risk-based decisions for the treatment of Hanford supplemental LAW, Congress should consider clarifying, in a manner that does not impair the regulatory authorities of EPA and the state of Washington, DOE's authority at Hanford to determine, in consultation with NRC, whether portions of the supplemental LAW can be managed as a waste type other than high-level waste.

    Agency: Congress
    Status: Open

    Comments: According to staff with the reports' addressees, Congress is considering whether to implement this Matter.
    Recommendation: To help ensure that DOE's treatment of Hanford's supplemental LAW is risk based and cost effective, the Secretary of Energy should develop updated information on the effectiveness of treating and disposing of all the different portions of Hanford's supplemental LAW with alternate methods or at alternate disposal sites, and based on this information, identify potential treatment and disposal pathways for different portions of Hanford's supplemental LAW, considering the risks posed by the LAW. In implementing this recommendation, DOE should take into account the results of the analysis required by Section 3134 of the National Defense Authorization Act for Fiscal Year 2017.

    Agency: Department of Energy
    Status: Open

    Comments: In July 2017, DOE told GAO that it has commissioned a team of National Laboratory experts that has begun working on an independent review of supplemental low-activity waste treatment options. DOE noted that this review will address the effectiveness of treating and disposing of Hanford's supplemental low-activity waste with alternate methods or at alternate disposal sites.
    Recommendation: To help ensure that DOE's treatment of Hanford's supplemental LAW is risk based and cost effective, the Secretary of Energy should have an independent entity develop updated information on the lifecycle costs of treating and disposing of Hanford's supplemental LAW with alternate methods or at alternate disposal sites. In implementing this recommendation, DOE should take into account the results of the analysis required by Section 3134 of the National Defense Authorization Act for Fiscal Year 2017.

    Recommendation: The Secretary of Energy should direct the Office of Nuclear Energy to reassess its decision to engage in discussions with potential host communities, screen sites, or conduct other site selection activities until key prerequisites to these efforts--such as revising health and safety regulations--have been addressed.

    Agency: Department of Energy
    Status: Open

    Comments: The National Defense Authorization Act for Fiscal Year 2017 prohibited DOE from spending money on a defense repository until the Secretary has developed an understanding of the costs and impacts to other priority programs within atomic energy defense activities. However, the President's fiscal year 2018 budget priorities include $120 million for DOE to resume licensing activities for the Yucca Mountain repository in Nevada. As of March 2017, a DOE official said they were waiting for authorization and direction on how to proceed.
    Recommendation: The Secretary of Energy should direct the Office of Nuclear Energy to conduct a comprehensive assessment, which adheres to the Office of Management and Budget guidance and best practices, of the benefits, costs, and schedules of the options it reviewed and provided to the President in 2015, and, in light of the new information and results of its assessment, revise--if needed--the report's conclusion that a strong basis exists to find that a defense HLW repository is required.

    Agency: Department of Energy
    Status: Open

    Comments: The Department of Energy (DOE) agreed with this recommendation in principle and the National Defense Authorization Act for Fiscal Year 2017 prohibited DOE from spending money on a defense repository until the Secretary has developed an understanding of the costs and impacts to other priority programs within atomic energy defense activities. However, the President's fiscal year 2018 budget priorities include $120 million for DOE to resume licensing activities for the Yucca Mountain repository in Nevada.

    Recommendation: To develop reliable cost estimates for the TRU waste removal project and for the TWF construction project at LANL, the Secretary of Energy should direct NNSA and the Office of Environmental Management to revise the cost estimate for the TRU waste removal project to ensure that it uses updated assumptions based on the current understanding of project conditions, such as the status of WIPP.

    Agency: Department of Energy
    Status: Open

    Comments: As of April 2017, Department of Energy (DOE) officials indicated that a revised life-cycle baseline cost estimate was prepared for all Office of Environmental Management mission work at Los Alamos National Laboratory, including transuranic waste removal work. DOE approved the revised cost estimate in July 2016. After we review documentation of the estimate, we will evaluate whether it is sufficient to close the recommendation.
    Recommendation: To develop reliable cost estimates for the TRU waste removal project and for the TWF construction project at LANL, the Secretary of Energy should direct NNSA to revise and update the TWF project's cost estimate by following all best practices for developing a reliable cost estimate that covers all life-cycle costs for better managing the project going forward.

    Agency: Department of Energy
    Status: Open

    Comments: The Department of Energy (DOE) agreed with the recommendation. As of March 2017, DOE indicated that Los Alamos National Laboratory prepared a cost estimate for the operations and maintenance of the Transuranic Waste Facility (TWF) facility in December 2015, which was reviewed and accepted by the responsible program offices. DOE indicated that the revised estimate reflected operational costs for a seven-year window and incorporated applicable best practices, including documentation of any significant deviations and uncertainties impacting the estimate, among other things. After we obtain documentation of the estimate, we will evaluate the action to determine whether it is sufficient to close the recommendation as implemented.
