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.

Environmental concerns have historically presented a major obstacle to expanding the use of nuclear energy worldwide. In the United States, more than ten states have implemented laws to restrict new construction of nuclear reactors until a spent nuclear fuel disposal plan is developed. At the same time, nuclear industries have been pioneering environmental and waste isolation technologies with long compliance periods, multi-barrier systems, and extensive regulations.
In this course, students will learn the foundational aspects of radioactive waste management, including storage, recycling, and disposal technologies and environmental impact assessment methodologies, as well as relevant regulations and history. This course provides a holistic perspective of the subject, considering the origins and impact of radioactive waste throughout the fuel cycle. Critical review of current technical solutions and policies is emphasized in the course.
