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.

In August 2020 a derecho hit Duane Arnold head on causing a loss of offsite power lasting about 24 hours. Winds speeds exceeded 80 mph for over 20 minutes with peak speeds exceeding 100 mph. A complication was debris fouling of service water pump suction strainers requiring bypassing one of the strainers. This session will describe what happened to the plant, how the plant successfully dealt with the event including site preparations, response and what could have been improved. In addition, the session will explore the risk insights gained on both Duane Arnold and other plants.
