Briefings

A new method successfully removes over 99% of radioactive technetium from liquid waste, addressing a priority contaminant at legacy nuclear sites like Sellafield and Hanford. The process targets the highly mobile chemical species of Technetium-99, which poses significant risks in environments where it moves readily through water and soil.

Key points

• Technetium-99 is a long-lived radioactive byproduct of nuclear fuel production and reprocessing.
• The method removes more than 99% of the contaminant from liquid waste.

Context

Technetium-99 forms a highly mobile chemical species that can move readily through water and soil, making it a priority contaminant at legacy nuclear sites including Sellafield in the U.K. and Hanford in the United States.

Limitations

Evidence is limited to the description of the contaminant's mobility and the removal efficiency; specific operational parameters, timeline data, or detailed results from the removal process are not provided.
