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.

The Fuel Cycle and Waste Management Division has hosted several "Closing the Nuclear Fuel Cycle" sessions as part of the ANS Grand Challenges Initiative that started in 2016. These sessions have focused on the use of large-scale commercial recycling (reprocessing + fuel fabrication) facilities (e.g., 1000 MTU/yr) that are considered very capital intensive and hence difficult to finance. A potentially more economical solution is to construct small modular reprocessing facilities that could be co-located with fuel fabrication facilities. Such facilities could also be constructed using additive manufacturing to further decrease costs. This panel session examines the feasibility, incentives, and potential drawbacks of using small modular recycling facilities to close the fuel cycle.
