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 Material Protection Accounting and Control Technologies program has completed a 2020 milestone to demonstrate Safeguards and Security by Design (SSBD) for a notional electrochemical reprocessing facility. The work has been outlined in a series of nine papers in a special issue of the Journal of Nuclear Materials Management. This panel session will describe key lessons learned from the SSBD process, the materials accountancy and physical protection approach, measurement technology development, and experimental testing. The approach and tools used in this work can be applied to other nuclear fuel cycle facilities in the future.
