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.

There is a strong history of efforts to reduce country’s stockpiles of nuclear weapons and the technology advancements of how to verify that these agreements were upheld. In this session we will explore the history of nuclear arms control agreements: the environment at the time, terms of the agreement, the verifications systems set-up, and their impact. Following a historical discussion, we will hear from experts in the field to talk about new technologies to monitor agreements.
