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.

A polar vortex descended into the central United States in February 2021. The unusually cold temperatures forced many power plants offline and sharply curtailed natural gas production, leading to multi-day blackouts in Texas and shorter blackouts across the Great Plains. All generator types were affected to some degree, including nuclear power plants. This panel will focus on the performance of energy systems and markets during the February 2021 cold weather event.
