Nuclear Waste: Waste Isolation Pilot Plant Recovery Demonstrates Cost and Schedule Requirements Needed for DOE Cleanup Operations
GAO-16-608: Published: Aug 4, 2016. Publicly Released: Aug 4, 2016.
The Department of Energy (DOE) did not meet its initial cost and schedule estimates for restarting nuclear waste disposal operations at the Waste Isolation Pilot Plant (WIPP), resulting in a cost increase of about $64 million and a delay of nearly 9 months. DOE incurred this cost increase and delay partly because it did not follow all best practices in developing the cost and schedule estimates. I...
Hanford Waste Treatment: DOE Needs to Evaluate Alternatives to Recently Proposed Projects and Address Technical and Management Challenges
GAO-15-354: Published: May 7, 2015. Publicly Released: May 7, 2015.
The Department of Energy's (DOE) two proposed facilities may help achieve Hanford's waste treatment mission by expediting treatment of some waste and addressing some technical challenges within the Waste Treatment and Immobilization Plant's (WTP) Pretreatment facility. However, DOE selected the facilities based on past proposals and excluded other potential alternatives from consideration. One fac...
Polar Weather Satellites: NOAA Needs To Prepare for Near-term Data Gaps [Reissued on January 16, 2015]
GAO-15-47: Published: Dec 16, 2014. Publicly Released: Jan 15, 2015.
The Joint Polar Satellite System (JPSS) program has recently completed significant development activities and remains within its cost and schedule baselines; however, recent cost growth on key components is likely unsustainable and risks remain that could increase the potential for near-term satellite data gaps. For example, technical issues experienced while developing a key instrument have led t...
Geostationary Weather Satellites: Launch Date Nears, but Remaining Schedule Risks Need to be Addressed
GAO-15-60: Published: Dec 16, 2014. Publicly Released: Jan 15, 2015.
The National Oceanic and Atmospheric Administration (NOAA)'s Geostationary Operational Environmental Satellite-R (GOES-R) program has made major progress in developing its first satellite, including completing testing of satellite instruments. However, the program continues to face challenges in the areas of schedule, cost, and functionality. Specifically, the program has continued to experience d...
Plutonium Disposition Program: DOE Needs to Analyze the Root Causes of Cost Increases and Develop Better Cost Estimates
GAO-14-231: Published: Feb 13, 2014. Publicly Released: Feb 13, 2014.
The Department of Energy's (DOE) National Nuclear Security Administration (NNSA) identified various drivers for the close to $3 billion increase in the estimated cost of the Plutonium Disposition program's two construction projects—the Mixed Oxide (MOX) Fuel Fabrication Facility and the Waste Solidification Building (WSB). These drivers included DOE's approval of the MOX facility's cost and sche...
Geostationary Weather Satellites: Progress Made, but Weaknesses in Scheduling, Contingency Planning, and Communicating with Users Need to Be Addressed
GAO-13-597: Published: Sep 9, 2013. Publicly Released: Sep 19, 2013.
The National Oceanic and Atmospheric Administration (NOAA) has completed the design of its Geostationary Operational Environmental Satellite-R (GOES-R) series and made progress in building flight and ground components. While the program reports that it is on track to stay within its $10.9 billion life cycle cost estimate, it has not reported key information on reserve funds to senior management. A...
Polar Weather Satellites: NOAA Identified Ways to Mitigate Data Gaps, but Contingency Plans and Schedules Require Further Attention
GAO-13-676: Published: Sep 11, 2013. Publicly Released: Sep 19, 2013.
The National Oceanic and Atmospheric Administration (NOAA) has made noteworthy progress on the Joint Polar Satellite System (JPSS) program by delivering data from its first satellite--the Suomi National Polar-orbiting Partnership (S-NPP)--to weather forecasters, completing significant instrument development for the next satellite (called JPSS-1), and reducing the program's life cycle cost estimate...
Department of Energy: Concerns with Major Construction Projects at the Office of Environmental Management and NNSA
GAO-13-484T: Published: Mar 20, 2013. Publicly Released: Mar 20, 2013.
In response to GAO reports over the past few years on management weaknesses in major projects (i.e., those costing $750 million or more), the Department of Energy (DOE) has undertaken a number of reforms since March 2009, including those overseen by the Office of Environmental Management (EM) and the National Nuclear Security Administration (NNSA). For example, DOE has updated program and project...
Hanford Waste Treatment Plant: DOE Needs to Take Action to Resolve Technical and Management Challenges
GAO-13-38: Published: Dec 19, 2012. Publicly Released: Jan 18, 2013.
The Department of Energy (DOE) faces significant technical challenges in successfully constructing and operating the Waste Treatment and Immobilization Plant (WTP) project that is to treat millions of gallons of highly radioactive liquid waste resulting from the production of nuclear weapons. DOE and Bechtel National, Inc. identified hundreds of technical challenges that vary in significance and p...
Nuclear Waste: Action Needed to Improve Accountability and Management of DOE's Major Cleanup Projects
GAO-08-1081: Published: Sep 26, 2008. Publicly Released: Sep 26, 2008.
The Department of Energy (DOE) spends billions of dollars annually to clean up nuclear wastes at sites that produced nuclear weapons. Cleanup projects decontaminate and demolish buildings, remove and dispose of contaminated soil, treat contaminated groundwater, and stabilize and dispose of solid and liquid radioactive wastes. Ten of these projects meet or nearly meet DOE's definition of major: cos...
