GAO: Grouting Hanford tank waste could cost more than $1.1B

Grouting Hanford’s low-level radioactive liquid tank waste could cost between $480 million and $1.1 billion, according to a report by the Government Accountability Office, which has repeatedly found that grouting (immobilizing waste in a concrete-like mixture) can accelerate cleanup at the Hanford Site and save billions of dollars when compared to mixing the waste with molten glass through the vitrification process.

Monday, June 12, 2023|1:00–2:45PM EDT|Marriott 7/8
Session Chair:
John Mattingly, Ph.D. (NCSU)
The National Academies of Sciences, Engineering, and Medicine conducted a study on advanced nuclear reactor fuel cycles, waste generation, and associated proliferation risks mandated by the US Congress. They published a report in early 2023 evaluating the merits and risks, entitled "Merits and Viability of Different Nuclear Fuel Cycles and Technology Options and the Waste Aspects of Advanced Nuclear Reactors." The American Nuclear Society reviewed the report and issued a letter in March 2023, agreeing with some but not all of the report's findings. This executive session panel will discuss the report’s main points and the Society's response and engage in an interactive discussion about areas of agreement and disagreement.
