Hanford Waste Treatment Plant: DOE is Pursuing Pretreatment Alternatives, but Its Strategy is Unclear While Costs Continue to Rise, Report to Congressional Committees [open pdf - 4MB]
From the Document: "The Hanford Site in Washington State contains large quantities of nuclear waste. EM [Department of Energy's (DOE) Office of Environmental Management] has been building the Waste Treatment and Immobilization Plant--which consists of multiple facilities, including a key pretreatment facility--to treat a large portion of the nuclear waste at Hanford. Under way since 2000 and costing over $11 billion to date--$3.8 billion of that spent on the pretreatment facility--the plant has faced technical challenges, cost overruns, and schedule delays. In late 2012, work on the pretreatment facility stopped until technical challenges could be resolved. In 2018, the U.S. Army Corps of Engineers reported that at current annual funding levels, completing the pretreatment facility on time would not be possible. Senate Report 116-48 accompanying the National Defense Authorization Act for fiscal year 2020 included a provision for GAO [Government Accountability Office] to review this project. This report examines (1) the cost of pretreatment efforts from fiscal year 2013 through fiscal year 2018, (2) the status of the technical challenges facing the pretreatment facility, and (3) the steps EM is taking to start treating waste by 2023 as required, among other things. GAO toured the facility, analyzed EM documents and expenditure data, and interviewed EM officials."
