Description:
Decades of nuclear materials production at the Department of Energy's (DOE) Savannah River Site in South Carolina have left 37 million gallons of radioactive liquid waste in 49 underground storage tanks. In December 2008, DOE entered into a contract with Savannah River Remediation, LLC (SRR) to close, by 2017, 22 of the highest-risk tanks at a cost of $3.2 billion. GAO was asked to assess: (1) DOE's cost estimates and schedule for closing the tanks at the Savannah River Site, and (2) the primary challenges, if any, to closing the tanks and the steps DOE has taken to address them. GAO visited the Savannah River Site and reviewed tank closure documents, as well as conducted an analysis of the construction schedule of the Salt Waste Processing Facility (SWPF), which is a facility vital to successful tank closure because it will treat a large portion of the waste removed from the tanks. GAO is making five recommendations to DOE to, among other things, clarify how cost increases should be requested by a contractor, as well as reviewed and approved by DOE and to ensure the SWPF construction schedule conforms to best practices. Although DOE generally agreed with two of our recommendations, they disagreed on the necessity of additional clarity on how cost increases should be requested by a contractor and that the SWPF construction schedule did not conform to best practices. We continue to believe our recommendations are valid.
